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

l
Complete the installation and debugging report.

 
6.
Reliability operation

 
l
After the completion of adjustment, single wind generator shall begin within 5
days the reliability operation for 250 hours.

 
l
The standard of reliability operation is that single wind generator runs
consecutively, stably, safely and unfailingly for 250 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 10% of the time for reliability operation.

 
l
Moreover, breakdowns incurred by the followings shall not be considered as
failures of fan motor:

 
l
Electric network failure (parameter of electric network is excluded in the
technical specification)

 
l
Meteorological conditions, including wind regime and ambient temperature, are
beyond the operating range specified in the technical specification.

 
l
During 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.

 
l
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,

 

--------------------------------------------------------------------------------

 

 
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 250-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.

 
l
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.

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%.
