    Appendix
1:Description
on composing and technical performance of contractual equipments

     

    1. Spec.
& model

     

    Guoce
Nordic GCN1000-59 system is grid connection Wind Turbine Generator System. Its
rating power is 1.0MW, consists of horizontal axis, double blades, drum-type
tower with upwind. Its service life of design is 20 years.

     

    2. Technology
description

     

    Design
aims of GCN1000-59 is translating wind energy into electric energy adopting wind
turbines of structure much lighter and simple than the traditional design. In
this way it can compete with other wind turbines and energy source.

     

    Material
quantity used for wind generator should be direct proportion with the load born
by the wind generator, thus the material utilization quantity must be the least.
Fatigue loading during the normal operation is mainly limited by design of
blade, wheel hub and yawing system.

     

    Main
function of yawing system is to make the blower fan towards the correct wind
direction. Simultaneously, provide flexible damp connection for nacelle and
turbine tower. Flexible and good damp design eliminates vibration accumulation
caused by any load in the structure. At the same time, characteristics of the
selected generator enables the possibility of reducing vibration generated by
driving torsional moment; otherwise, the driving torsional moment will generate
strong vibration under the impact of turbulent flow and shear wind.

     

    When the
Wind Turbine Generator System stops in the maximum wind speed, blower fan design
must consider the ultimate load, ultimate load keeps a direct proportion with
the exposed area in the wind. Two blades design under this environment has the
least exposed area in the wind. According to the calculation of static state
load, the load of blower fan under other situation is the same as the above: for
example, over run in case of electric grid failure, fast change of wind
direction and etc.

     

    The Wind
Turbine Generator System belongs to slender design. Blade, turbine tower and
other parts are easy to generate vibration. In order to maintain low load,
calculating carefully the characteristic frequency of all parts and aforesaid
attenuation yawing system and generator vibration are very necessary. For the
purpose of better dynamic characteristic of wind generator, the complicated
service condition of the entire wind generator will need a large amount of
computer calculation and simulation.

     

    The fixed
pitch speed loss type power regulation and control under high wind speed is an
important character to realize simple design. Other important simple design will
be realized through the integration of yawing system (this system
doesn’t need very expensive yawing brake device commonly used in other large
wind generator)
and principal axis gear-box.

    

    
      
        
           

        

        
           

          
            

          

        

        
           

        

      

    

     

    Chassis
design provides a compact structure for blower fan, round section steel chassis
connects with the gear casing with flange.

     

    All the
above-mentioned characters enable total weight of blower fan with double blades
oscillation axis design 30% less than other wind generator with the same
power.

     

    Det
Norske Veritas has authenticated the design.

     

    Blades

     

    Blades
are made of fiber glass reinforced resin. Bolt to the wheel hub through steel
strap crimp connection to the blade root. Paint the external plastic resin layer
of blade into grey and polish, and reduce air resistance.

     

    Blade tip
can be rotated through internal device, and stop the blower fan operation if
necessary. Prevent the deflexion of blade tip through hydraulic pressure column
of wheel axle under normal operation. The blade tip rotation can become spoiler
through releasing the pressure of hydraulic cylinder if necessary.

     

    Blade
lightning protection is designed according to standards of IEC 61400-24 Ed
1.

     

    Hub

     

    Design of
wheel hub is compact with lighter weight, and distance from principal axis of
gear-box to the center of wheel hub is short. Wheel hub is made of nodular cast
iron. The so-called rocker design reduces the fatigue load of the entire wind
generator.

     

    Hydraulic
pressure component in the wheel hub can control the blade tip, which can be
overhauled through the manhole on the wheel axle. Power is supplied through slip
ring. Elliptical hole on the blade flange can adjust the blade angle of attack.
When maintenance is required, wheel hub can be locked.

     

    Gear-box

     

    Planet
gear-box will increase low rotating speed of impeller to high rotating speed
suitable for the generator operation. Gear-box includes also principal bearing,
which makes the wind generator very compact. Gear-box flange is connected to the
chassis composed with pipes. Adopt splash lubrication and realize heat emission
by connecting radiator of generator with liquid heat emission circulation.
Temperature sensor indicates oil temperature and closes the wind generator when
oil temperature is too high. Sensor measures oil tank temperature and fast
bearing temperature. Two system of heating devices installed on the oil tank
area in order to preheat lubricant in cold weather.

     

    High-speed
shaft and machinery brake

     

    Counter
shaft is connected with brake disc and two flexible brake sheets. Two brake
sheets adopt brake pad without asbestos. When hydraulic pressure device is
releasing
(passive system) , brake sheet
closes through spring. Control system will monitor the abrasion and malfunction
of brake sheet.

    

    
      
        
           

        

        
           

          
            

          

        

        
           

        

      

    

     

    Chassis
and support cylinder

     

    Steel
welding round column chassis is very compact, and easy to be manufactured. Gear
casing flange is connected to the front side of chassis, generator is connected
to the back side of chassis, and lower part of chassis connects with yawing
bearing through elastic material. Elastic material is used for absorption of
vibration, so as to prevent the vibration of gear casing and generator being
transmitted to the turbine tower, otherwise it may generate noise. Maintenance
personnel can realize maintenance through manhole on the yawing bearing and
chassis.

     

    Nacelle

     

    Nacelle
provides an indoors maintenance space with a standing height for the maintenance
person. The nacelle is bolted with upper part and lower part made of fibre glass
reinforced polyester. The bottom of the nacelle should cover with non-slip mat;
wall and ceiling in the nacelle have covered with materials that can absorb
sound.

     

    Prominence
of chassis top can transfer equipment through door at the end of nacelle or the
turbine tower. It can also be used to decrease the blade on the ground. Port at
the end can use survival equipment for life rescue under emergency situation,
such as, internal fire. There is a heat exchanger on the external top of nacelle
for emitting surplus heat of gear casing and generator. The lightning rod and
wind speed anemoscope are installed on the external top of nacelle. These
equipments on the top can be maintained through the door of nacelle
top.

     

    Nacelle
has set personnel safety rope tying point, including safety rope tying points to
entering the nacelle and top.

     

    Sealing
of the nacelle is good, which can prevent the entry of blowing dust with
reliable rain proof and moisture resistance.

     

    Yawing
system

     

    Chassis
is connected with nacelle through yawing bearing, and realize blower fan towards
wind direction. Three planet gear-box will operate on the inside gear of yawing
bearing driven by hydraulic motor.

     

    Under all
operation conditions – yawing or not yawing - yawing system realizes small
breadth and damped weaving movement of the entire wind power nacelle. Only when
maintenance is required, yawing system will be locked and no movement is
allowed.

     

    The
yawing system has automatic unmooring function, the setting condition of yawing
counter can guarantee automatic unmooring and reset after the cable reel,
simultaneously, the system has set cable reel protection device, once the
automatic unmooring function is failure, while cable reel to certain extent, the
cable reel protection device will send accident signal of emergency
stop.

    

    
      
        
           

        

        
           

          
            

          

        

        
           

        

      

    

     

    Electric
system

     

    The
electric system includes slip adjustable single speed asynchronous generator,
inside variable resistor connects rotor coil. Slip range 1-5%, generator adopt
liquid cooling method.

     

    Power can
be transmitted to the tower bottom through flexible cable enwinding to two
directions.

     

    Turbine
tower

     

    Column
cone shaped turbine tower is welded with steel sheets. Maintenance personnel
enter from the door on the ground. Vertical ladder is set in the tower, which is
equipped with drop safe guardrail. Clean the surface of turbine tower by
sand-sweeping and paint for corrosion protection, and color should be the same
with blade.

     

    According
to the different situation on the spot, equip turbine tower with different
height, so as to adapt to the situation on the island, bank and
sea.

     

    Control
system

     

    Control
system is based on a microprocessor. Control system controls the operation of
entire wind generator, as well as the wind generator stillness or idling in
breeze, connect with generator under normal rotating speed, adjust orientation
and wind direction of wind generator, and unmooring (by rotating the
nacelle) if
necessary, control all functions, turn off the blower fan in case of emergency
or wind power too strong. Connect the blower fan control system through
telephone line by using a set of PC with modem.

     

    If the
brake moment of generator disappears, if electric component failure or electric
grid fluctuation, the blower fan will accelerate to high rotating speed. The
control system can safely handle these situation and brake through complicated
steps. The control system will send out common stop instruction if any parameter
failure, such as electric grid voltage (electric grid
failure),
rotating speed, power, temperature, vibration and etc. Emergency stop will be
implemented in case of control system failure through “Watch-dog” function.
Control system machinery brake can be realized through cutting off the power of
hydraulic pressure solenoid valve by releasing blade top hydraulic cylinder
pressure. Blade tip acts through centrifugal force, while brake sheet acts
through mechanical spring. When electric grid fails, brake will start due to
power off. Any action of machinery brake or blade tip spoiler will make the wind
generator to reduce to safe low rotating speed.

     

    The final
safety measure is that there is a safety valve in the hydraulic pressure
component of wheel hub, it will release oil in the oil cylinder to control blade
tip if hydraulic pressure is too high, at this time, and the blower fan stays in
over speed status. And then spoiler function will reduce the blower fan rotating
speed.

    

    
      
        
           

        

        
           

          
            

          

        

        
           

        

      

    

     

    Hydraulic
system

     

    Hydraulic
system mainly consists of hydraulic pump station, oil circuit, control component
and actuating mechanism to be as the power of brake device. Brake device is
installed on the fast axis, brake disc material should comply with the
requirements of low temperature, and dynamic balancing test should be made
before ex-factory. The unit has equipped with two independent brake system, so
as to guarantee that any condition of the wind generator unit (including load
off of electric grid failure) and wind wheel
rotating speed stops at maximum rotating speed. Blade tip spoiler operates based
on aerodynamic force principle, which will be used directly on the ferries
wheel.

    Monitoring

     

    The
operation of wind generator is realized through the panel installed at the
nacelle and tower bottom and LCD display. These controls include starting,
switch-off, switching to manual mode and confirmation of error message. These
functions may also be fulfilled through remote telephone line. Monitoring system
also provides basic parameter statistics for generator’s run including
generating capacity, wind power and failure history etc.

              After
      the completion of debugging, single wind generator shall begin within 5
      days the reliability operation for 360 hours. If reliability operation is
      not made after 5 days, the buyer will consider that this equipment is not
      qualified.

            

    

     

    

    
      
        
           

        

        
           

          
            

          

        

        
           

        

      

    

    

    
      	
               
      

            	
              l

            	
              The
      standard of reliability operation is that single wind generator runs
      consecutively, stably, safely and unfailingly for 360 hours. Wind
      generator’s automatic and customized remote restoration and manual
      restoration needing no repairing or replacement for any part are allowed
      during this period. Any shutdown through the above mentioned restoration
      can later be re-run will not be considered as failure, but the accumulated
      shutdown time through restoration correction may not exceed 6% of the time
      for reliability operation.

              During
      reliability operation period, the accumulative power-generating time of
      wind generator shall not be less than 180 hours. If the time is not
      sufficient, the reliability operation will extend to 180 hours for
      accumulated power-generating time, but the extended time does not exceed
      240 hours at most.

            

    

    
      	
               
      

            	
              l

            	
              During
      reliability operation period, any failure of the seller’s equipment shall
      not appear (i.e. after shutdown, wind generator can not be re-run through
      restoration without repairing or replacement of components.) once failure
      appears, the reliability running time will be
  re-recorded.

            

    

    
      	
               
      

            	
              l

            	
              After
      each set passes consecutive 360-hour unfailing consecutive stable running,
      the buyer, the seller and the final user will sign pre-acceptance
      certificate of this set to prove that this set has passed the inspection
      of reliability operation.

              If
      reliability of any set does not reach all the indexes and requirements
      specified in the contract, the seller shall repair or replace immediately
      and this set will be re-tested for reliability operation. When the unit
      re-reaches the indexes and requirements for reliability operation
      pre-acceptance, the buyer signs “passed” certificate on the pre-acceptance
      certificate.

Calculation and inspection method for power curve of wind generator

     

    During
the quality guarantee period, the seller’s guarantee value on power curve is
more than or equal to 95% of the calculated amount of power generation on the
basis of guaranteeing the power curve.

     

    If the
buyer has questions about the power curve of any set, it has the right to raise
the question in the quality guarantee period and to measure the power curve by
employing an internationally famous test organization (such as Garrad Hassan, PB
Power or MEASNET member) according to the IEC 61400-12 standard on its own
expenses. This test shall not affect the proceeding of quality guarantee period.
If the result of the test shows that the set does not reach the guaranteed value
on power curve:

     

    
      	
               
      

            	
              l

            	
              The
      seller shall compensate the buyer the fees for conducting the power curve
      test.

            

    

    
      	
               
      

            	
              l

            	
              The
      seller shall pay penalty for not reaching the guaranteed power curve value
      to the buyer in accordance with article 10.12 of the
    contract.

            

    

    

    
      
        
           

        

        
           

          
            

          

        

        
           

        

      

    

     

    Formula
for validating guaranteed power curve value:

     

    Validating
generating capacity (S)
(unit: KW/H)

     

    Actual
guaranteed value (W) =
—————————————  ×100%

     

    Guaranteed
generating capacity (S)
(unit: KW/H)

     

    Validating
generating capacity (S)
= wind frequency (WF) for calculating generating capacity × power curve value
validated by a third party

     

    Guaranteed
generating capacity (B)
= wind frequency (WF) for calculating generating capacity × power curve value
validated by the seller.

     

    Calculation
of power amount shall be conduced with EXCEL or ALWIN. Wind frequency used for
calculating power amount use vibound distribution or on-site actual wind
frequency (wind measuring data require no less than one year) approved by both
parties. This calculation shall be made by an independent authentification
organization.

     

    II.
Inspection of availability

     

    During
quality guarantee period, the seller’s guarantee value for availability is more
than or equal to 97%.

     

    1.
Calculation of availability

     

    The
formula for calculating availability is as follows:

     

     × 100%,

     

    Among
which

     

    A        availability
[%]

     

    P         statistical
time part after modification The time part is the Gregorian calendar year, i.e.
8760 hours for general year and 8784 hours for leap year.

    Appendix
1:Description
on composing and technical performance of contract equipment

     

    1. Spec.
& model

     

    Guoce
Nordic GCN1000/56.6 system is asynchronous grid connection wind turbine
generator. Its rating power is o.986 MW, consists of horizontal axis, double
blades, tubular tower with upwind. Its service life of design is 20
years.

     

    2.
Technical description

     

    The
GCN100/56.6 system is designed to transfer wind energy into electric energy by
using a lighter and simpler wind generator than a traditional one.

     

    The scope
of operating temperature of GCN100/56.6 system is between -40oC and 40oC, and so is that
of its survival temperature; it is suitable for operating in place where the
altitude is below 100m, and the design service life for all the system and its
key components is not less than 20 years.

     

    In order
to ensure its smooth operation at the temperature of -40oC, the system
shall be designed to fully meet the requirements for low-temperature operation
in terms of mechanical, hydraulic pressure, cooling and electrical
conditions.

     

    All the
key components and structural members shall use cold resistant materials, for
example, use QT400-18AL for wheel hub, and Q345E for nacelle classis, support
cylinder and turbine tower and so on. The operating working temperature of
hydraulic system and hydraulic oil is also -40oC. The cooling
system shall be added with water-and-glycol mixed solution with the mixture
ratio of 45%/55% (to be adjusted), to ensure that it doesn’t freeze at -40oC. Lubricating
system of main gear case is equipped with oil heater which may automatically
start when the temperature is below -5oC.

     

    In
addition, all the electrical cabinets are equipped with active heating system to
prevent the over-low temperature in the cabinet. Meantime, touch screen or
liquid crystal screen shall use model of cold resistant to ensure system’s
normal operation under low temperature. The main cable shall be dedicated
cold-resistant torsional cable which may carry out torsion operation at 40oC.

     

    Under the
extreme weather conditions, the GCN1000/56.6 system can withstand extreme wind
with the speed of 55.8m/s (limiting value of 10s). Under normal operation, the
GCN1000/56.6 system, thanks to its unique flexible design, may alleviate load
fluctuations caused by factors such as wind variation (e.g. unstable air flow
produced by wake flow in turbulent flow and wind field) and wind shear and so
on, so as to substantially lengthen the system’s structural
life-time.

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    Particular
flexible yawing system is to make the blower fan towards the correct wind
direction combining
with active yawing and passive yawing operation. Simultaneously, provide
flexible damp connection for wind turbine nacelle chassis and turbine tower.
Flexible and good damp design eliminates vibration accumulation caused by any
load in the structure.

     

    When the
Wind Turbine Generator System stops in the maximum wind speed, blower fan design
must consider the ultimate load, ultimate load keeps a direct proportion with
the exposed area in the wind. Two blades design under this environment has the
least exposed area in the wind which relatives to the three blades wind turbine.
According to the calculation of static state load, the load of blower fan under
other situation is the same as the above: for example, over run in case of
electric grid failure, fast change of wind direction and etc.

     

    The
GCN1000/56.6 set belongs to slender design with the slender flexible tower.
Blade, blades, turbine tower and other parts are easy to generate vibration. In
order to maintain low load, calculating carefully the characteristic frequency
of all parts and aforesaid attenuation yawing system and generator vibration are
very necessary. For the purpose of better dynamic characteristic of wind
generator, the complicated service condition of the entire wind generator will
need a large amount of computer calculation and simulation.

     

    The fixed
pitch speed loss type power regulation and control under high wind speed is an
important character to realize simple design. Other important simple design will
be realized through the integration of yawing system (this system doesn’t need
the yawing brake device commonly) and principal axis gear-box.

     

    Chassis
design provides a compact structure for blower fan, round section steel chassis
connects with the gear casing with flange.

     

    All the
above-mentioned characters enable total weight of blower fan with double blades
oscillation axis design 25% less than other wind generator with the same
power.

     

    Det
Norske Veritas has authenticated the design.

     

    Blades

     

    Blades
are made of fibre glass reinforced resin. Bolt to the wheel hub through steel
strap crimp connection to the blade root. Paint the external plastic resin layer
of blade into grey and polish, and reduce air resistance.

     

    Blade tip
can be rotated through internal device, and stop the blower fan operation if
necessary. Prevent the deflexion of blade tip through hydraulic pressure column
of wheel axle under normal operation. The blade tip rotation can become spoiler
through releasing the pressure of hydraulic cylinder if
necessary.

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    Wheel
hub

     

    Design of
wheel hub is compact with lighter weight, and distance from principal axis of
gear-box to the center of wheel hub is short. Wheel hub is made of nodular cast
iron. The so-called rocker design reduces the fatigue load of the entire wind
generator.

     

    Hydraulic
pressure component in the wheel hub can control the blade tip, which can be
overhauled through the manhole on the wheel axle. Power is supplied through slip
ring. Elliptical hole on the blade flange can adjust the blade angle of attack.
When maintenance is required, wheel hub can be locked.

     

    Gear-box

     

    Planet
gear-box will increase low rotating speed of impeller to high rotating speed
suitable for the generator operation. Gear-box includes also principal bearing,
which makes the wind generator very compact. Gear-box flange is connected to the
chassis composed with pipes. Adopt splash lubrication and realize heat emission
by connecting radiator of generator with liquid heat emission circulation.
Temperature sensor indicates oil temperature and closes the wind generator when
oil temperature is too high. Sensor measures oil tank temperature and fast
bearing temperature. Two system of heating devices installed on the oil tank
area in order to preheat lubricant in cold weather.

     

    High-speed
shaft and machinery brake

     

    Counter
shaft is connected with brake disc and two flexible brake sheets. Two brake
sheets adopt brake pad without asbestos. When hydraulic pressure device is
releasing(passive
system),
brake sheet closes through spring. Control system will monitor the abrasion and
malfunction of brake sheet.

     

    Chassis
and support cylinder

     

    Steel
welding round column chassis is very compact, and easy to be manufactured. Gear
casing flange is connected to the front side of chassis, generator is connected
to the back side of chassis, and lower part of chassis connects with yawing
bearing through elastic material. Elastic material is used for absorption of
vibration, so as to prevent the vibration of gear casing and generator being
transmitted to the turbine tower, otherwise it may generate noise. Maintenance
personnel can realize maintenance through manhole on the yawing bearing and
chassis.

     

    Nacelle

     

    Nacelle
provides an indoors maintenance space with a standing height for the maintenance
person. The nacelle is bolted with upper part and lower part made of fibre glass
reinforced polyester.

     

    There is
a heat exchanger on the external top of nacelle for emitting surplus heat of
gear casing and generator. The lightning rod and wind speed anemoscope are
installed on the external top of nacelle. These equipments on the top can be
maintained through the door of nacelle top (If maintain out of nacelle, the
protective measures should be done).

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    Nacelle
has set personnel safety rope tying point, including safety rope tying points to
entering the nacelle and top.

     

    Sealing
of the nacelle is good, which can prevent the entry of blowing dust with
reliable rain proof and moisture resistance.

     

    Yawing
system

     

    Chassis
is connected with nacelle through yawing bearing, and realize blower fan towards
wind direction. Three planet gear-box will operate on the inside gear of yawing
bearing driven by hydraulic motor.

     

    Under all
operation conditions – yawing or not yawing - yawing system realizes small
breadth and damped weaving movement of the entire wind power nacelle. Only when
maintenance is required, yawing system will be locked and no movement is
allowed.

     

    The
yawing system has automatic unmooring function, the setting condition of yawing
counter can guarantee automatic unmooring and reset after the cable reel,
simultaneously, the system has set cable reel protection device, once the
automatic unmooring function is failure, while cable reel to certain extent, the
cable reel protection device will send accident signal of emergency
stop.

    Power can
be transmitted to the tower bottom through flexible cable enwinding to two
directions.

     

    Turbine
tower

     

    Column
cone shaped turbine tower is welded with steel sheets. Maintenance personnel
enter from the door on the ground. Vertical ladder is set in the tower, which is
equipped with drop safe guardrail. Clean the surface of turbine tower by
sand-sweeping and paint for corrosion protection, and color should be the same
with blade.

     

    According
to the different situation on the spot, equip turbine tower with different
height, so as to adapt to the situation on the island, bank and
sea.

     

    Control
system

     

    Control
system is embedded system based on a microprocessor. Control system controls the
operation of entire wind generator, as well as the wind generator stillness or
idling in breeze, connect with generator under normal rotating speed, adjust
orientation and wind direction of wind generator, and unmooring(by rotating the
nacelle)if
necessary, control all functions, turn off the blower fan in case of emergency
or wind power too strong. Information transmission of the blower fan control
system will be done through fibre-optical (The mode of control system needs to
be determined).

     

    If the
brake moment of generator disappears, if electric component failure or electric
grid fluctuation, the blower fan will accelerate to high rotating speed. The
control system can safely handle these situation and brake through complicated
steps. The control system will send out common stop instruction if any parameter
failure, such as electric grid voltage(electric grid
failure),
rotating speed, power, temperature, vibration and etc. Emergency stop will be
implemented in case of control system failure through “Watch-dog” function.
Control system machinery brake can be realized through cutting off the power of
hydraulic pressure solenoid valve by releasing blade top hydraulic cylinder
pressure. Blade tip acts through centrifugal force, while brake sheet acts
through mechanical spring. When electric grid fails, brake will start due to
power off. Any action of machinery brake or blade tip spoiler will make the wind
generator to reduce to safe low rotating speed.

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    The final
safety measure is that there is a safety valve in the hydraulic pressure
component of wheel hub, it will release oil in the oil cylinder to control blade
tip if hydraulic pressure is too high, at this time, and the blower fan stays in
over speed status. And then spoiler function will reduce the blower fan rotating
speed.

     

    The wind
generator shall be equipped with the function of voltage penetration to
guarantee it can’t be cut off from the electric grid when voltage of electric
grid fluctuates, also the braking system of wind generator shall be taken
complete measures for preventing oil leakage and fire.

     

    The
control system shall possess perfect network function to meet communication
protocol of dispatching system, thus realizing the bidirectional data
transmission of dispatching system.

     

    Hydraulic
system

     

    Hydraulic
system mainly consists of hydraulic pump station, oil circuit, control component
and actuating mechanism to be as the power of brake device. Brake device is
installed on the fast axis, brake disc material should comply with the
requirements of low temperature, and dynamic balancing test should be made
before ex-factory. The unit has equipped with two independent brake system, so
as to guarantee that any condition of the wind generator unit(including load off
of electric grid failure)and wind wheel
rotating speed stops at maximum rotating speed. Blade tip spoiler operates based
on aerodynamic force principle, which will be used directly on the ferries
wheel.

    In case
of any other stopped states, the wind generator shall be able to be started
manually. If there are some failures of central monitoring system and control
system, the wind generator shall be only started in a manual manner when it was
stopped.

     

    The
central monitoring system shall possess anti-electromagnetic ability of
corresponding grading so that the arrangement of components of all control and
protection system could avoid the electromagnetic interference from inner
electric system.

     

    The
central system provides the communication function with the monitoring system of
substation and open communication protocol, so as to realize the data exchange
with the monitoring system of substation.

     

    The
electric network shall be equipped with remote monitoring system to monitor the
running state of wind generator and provide full functions of form making and
printing for parameters including wind speed, power, yawing angle, generated
energy, etc, and be able to receive dispatching data from BMS system of electric
network.

     

    The
remote monitoring system shall be able to meet the requirements of remote
monitoring, and the data format and communication protocol shall be compatible
with other monitoring systems

Overall
principle of on-site inspection

    

    On-site
inspection refers to the wind generator equipment inspection upon arriving the
buyer’s shipping port and installation site.

    
      	
               
      

            	
              l

            	
              After
      the equipment is transported to the shipping port of the buyer, both the
      seller and the buyer shall inspection whether the external packing is
      damaged. The seller is responsible for repairing in case of
      damage.

            

    

    
      	
               
      

            	
              l

            	
              The
      seller’s equipment packing must meet the requirement for domestic land
      transportation to the arranged site. The seller shall assume the fees if
      it does not meet the transport conditions. After the equipment is
      transported to the installation site of the buyer, both parties jointly
      inspection whether the external packing is damaged. The seller shall
      assume the penalty if the damage is not caused by
    transport.

            

    

    
      	
               
      

            	
              l

            	
              After
      the equipments arrive at the site and inspectioned through custom and
      commercial department, both parties inspection components of wind
      generator and sign the recording table of delivery
    situation.

            

    

    
      	
               
      

            	
              l

            	
              If
      situations such as wrong types or shortage of equipments are found, all
      the liabilities are born by the
seller.

            

    

    
      	
               
      

            	
              l

            	
              After
      completing equipment hoisting, the seller’s employees are responsible for
      installation and adjustment of wind generators. The seller shall perform
      the adjustment with the participation of the buyer’s employees. After
      adjustment is completed, the seller shall sign on the adjustment report
      and submit it to the buyer, and inform the buyer of the completion and
      that the 250-hour reliability operation may be
  conducted.

      generator’s automatic and customized remote restoration and manual
      restoration needing no repairing or replacement for any part are allowed

      can later be re-run will not be considered as failure, but the accumulated
      shutdown time through restoration correction may not exceed 10% of the
      time for reliability operation.

      the operating period for reliability, the accumulated generation time
      shall be no less than 180 hours. If not, the operation for reliability
      will be carried on until it reaches the minimum 180 hours. During the
      period, in case of the occurrence of rated wind speed, the system shall
      reach the rated output power; if no such occurrence, the time for trial
      operation will be extended. The extended time, neither for assessment on
      accumulated generation time nor assessment on rated working condition,
      shall be not longer than 250 hours. During the extended period, the
      operation for reliability will be considered as passed as long as the
      accumulated generation time or the rated output power is satisfied.
      Moreover, the system, if failing to satisfy the accumulated time or the
      rated wind speed due to wind conditions but operating without any
      breakdowns during the entire period, will be considered as
      qualified.

              During
      reliability operation period, any failure of the seller’s equipment shall
      not appear (i.e. after shutdown, wind generator can not be re-run through
      restoration without repairing or replacement of components.) once failure
      appears, the reliability running time will be
  re-recorded.

    2.
Calculation and inspection method for power curve of wind generator

     

    During
the quality guarantee period, the seller’s guarantee value on power curve is
more than or equal to 95% of the calculated amount of power generation on the
basis of guaranteeing the power curve.

    
      
         

      

      
        
        

        
          

        

      

      
         

      

    

     

    If the
buyer has questions about the power curve of any set, it has the right to raise
the question in the quality guarantee period and to measure the power curve by
employing an internationally famous test organization (such as Garrad Hassan, PB
Power or MEASNET member) according to the IEC 61400-12 standard on its own
expenses. This test shall not affect the proceeding of quality guarantee period.
If the result of the test shows that the set does not reach the guaranteed value
on power curve:

     

    
      	
               
      

            	
              l

            	
              The
      seller shall compensate the buyer the fees for conducting the power curve
      test.

            

    

    
      	
               
      

            	
              l

            	
              The
      seller shall pay penalty for not reaching the guaranteed power curve value
      to the buyer in accordance with article 11.7 of the
    contract.

            

    

    
      
         

      

      
        
        

        
          

        

      

      
         

      

    

     

    Formula
for validating guaranteed power curve value:

     

          Validating
generating capacity (S)
(unit: KW/H)

     

    Actual
guaranteed value (W) =
—————————————  ×100%

     

                      Guaranteed
generating capacity (S)
(unit: KW/H)

     

    Validating
generating capacity (S)
= wind frequency (WF) for calculating generating capacity × power curve value
validated by a third party

     

    Guaranteed
generating capacity (B)
= wind frequency (WF) for calculating generating capacity × power curve value
validated by the seller.

     

    Calculation
of power amount shall be conduced with EXCEL or ALWIN. Wind frequency used for
calculating power amount use vibound distribution or on-site actual wind
frequency (wind measuring data require no less than one year) approved by both
parties. This calculation shall be made by an independent authentification
organization.

     

    II.
Inspection of availability

     

    During
quality guarantee period, the seller’s guarantee value for availability is more
than or equal to 95%.

     

    1.
Calculation of availability

     

    The
formula for calculating availability is as follows:
