instructions or follow the instructions given by site service technicians of
seller while carrying out construction, installation or commissioning and such
actions lead to equipment damage, the buyer will assume responsibility for
replacement and repair. However, seller has the obligation to provide needed
replacement parts. For parts urgently requested by the buyer, seller should
arrange the fastest delivery at its own cost.
 
11.3.3 To accommodate design, installation, commissioning, operation and
maintenance, seller will provide installation supervision, training to staffs of
the buyer and 24-month quality warranty as requested in the “service” part of
the contract.

to contract, it is deemed as responsibility of seller. In this case, the buyer
has rights to make claim against seller. In case of doubt by seller, clause
9.2.7 will apply. Otherwise, seller will provide immediate and free of chare

service to the buyer and take all the possible actions needed to maintain
performance of such equipment.
 
11.8  For serious defects with contract equipment during warranty period due to
fault on side of seller, that is, six main components (vane, gear box,
generator, deviation system, electrical control system and tower) cannot
continue the operation due to such defects, then the warranty period for such
components will be 24 months starting from the date of corrections are

A. When delivery or payment is delayed for 1-4 weeks, for each week, the penalty
is 0.25% of the delayed amount.
 
B. When delivery or payment is delayed for 5-8 weeks, for each week, the penalty
is 0.4% of the delayed amount.
 
C. When delivery or payment is delayed for over 8 weeks, for each week, the
penalty is 1% of the delayed amount.

used in the calculation. However, total of the penalty from the delayed delivery
of equipment under the contract will not exceed the total amount of contract
equipment by 5%. Price reduction or indemnity does not relieve seller of his
reliabilities during warranty period. Seller paying penalty does not relieve
seller of the obligation to continue the delivery of contract equipment. For
equipments which are delayed for over 6 months and have significant impact on
installation and trial operation, the penalty to be paid by seller to the buyer
can exceed the total amount of equipment by 5%. At the same time, the buyer has
rights to terminate the contract in partial or in full.

delivery as scheduled in the specification of the contract, both parties will
verify the key technical materials, design and planned materials which affect
construction progress. For each week delay, penalty is 0.2% of contract amount.
Delayed delivery is counted as specified in clause 6.10.

very important for seller. Such delivery must be specified in the timing plan as
in annex 10.
 
11.13 If additional costs occur to seller due to delay to civil, mechanical or
electrical works, the seller will make claim request to the buyer. Such
compensation will be calculated based on physical costs, including inventory,
but not including profit. However, if above delays are longer than 30 days,
seller cannot make claim request. In case of excess of 30 days, compensation
payout will be counted from the 30th day.

Appendix 1：Description on composing and technical performance of contractual
equipments
 
1. Spec. & model
 
Guoce Nordic DW1.0/56 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 DW 1.0/56 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 desi.
 
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.
 
Blade lightning protection is designed according to standards of IEC 61400-24 Ed
1.
 
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. 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.

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:

 
 

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

 

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

 
·
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
