Appendix 1 Contract Equipment and Technical Characteristics

1. Model

The wind turbine generator system (WTGS) supplied by the seller is upwind
horizontal-axis two-blade fixed-pitch gird-connected wind turbine generators
modeled GCN1000/59 with the rated power of 1000kW.

2. Technical Description

The operating temperature range of GCN1000/59 WTGS is -30℃~40℃ and the survival
temperature of -40℃~50℃. It can adapt to the running environment below the
altitude 1500m. The design life of the WTGS and key components is more than 20
years. The nacelle anemometer is provided with the functions of anti-freezing,
lightning protection and withstanding wind and sandstorm.

To ensure normal running of the WTGS below -30℃, the WTGS design gives
sufficient considerations to running at low temperature in aspects of
mechanical, hydraulic, cooling and electrical. Low-temperature-resistant
materials are selected for important components and structural parts. For
example, hub selects QT400-18AL, and nacelle bedplate, supporting structure and
tower select Q345E. The working temperature of hydraulic system and hydraulic
oil is also -40℃. The mixture of water and glycol with the proportion of 45%/55%
is filled into the cooling system to prevent icing at -40℃. The lubricating oil
system of the main gearbox is equipped with oil heater which will automatically
start at a temperature lower than -5℃.

In addition, all electrical cabinets are armed with active heating device to
prevent cabinet inside from too low temperature. Meanwhile, for ensuring normal
operation at low temperature, the touch screen or LCD screen selects
low-temperature-resistant type. The main cable is the special
low-temperature-resistant cable against torsional resistance so as to allow
torsion at -40℃.

In extreme weather conditions, GCN1000/59 WTGS may withstand the extreme wind
speed of 55m/s (3s mean). During normal running, the unique flexible design of
GCN1000/59 WTGS moderates the effects of load fluctuations caused by variations
of wind (such as: turbulence and unstable air flow produced by wake at wind
site) and wind shear etc, and thus significantly improving the structural life
of the WTGS.

Det Norske Veritas has already certified the WTGS design of the seller.

2.1 Blades

Blades of GCN1000/59 adopt the aerodynamic configuration specific for optimum
design of two-blade WTGS. The blades are made of fiber glass reinforced
unsaturated polyester resin. High strength bolts are embedded at the root of
blades. Blade surface is matte finished to avoid matte surface.

 
 
50

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

 
  
For enhancing the efficiency of WTGS in low and medium wind speed section
(7-10m/s), a vortex generator is mounted near the root of blade to reduce the
aerodynamic loss. Meanwhile, to keep the blade stable during stall due to high
wind speed, a specially designed stall strip is installed in a proper position
at the leading edge of blade.

To stop the WTGS immediately in the event of emergency, a spoiler is mounted at
the tip of blade. It can spread by the centrifugal force within 2 seconds to
rapidly stop the wind turbine. At normal running, it is retracted by the
hydraulic system on hub; in case of emergency, pressure of hydraulic cylinder is
released to set free the tip of blade and stop the wind turbine.

2.2 Hub

The hub is of compact structure and lightweight. The hinged swing design
effectively reduces the fatigued load of the whole wind turbine generator. The
hub body divides into hub and hub attachments made of Q345E ductile cast iron.
Elastic elements made by special rubber are installed at proper positions of hub
for shake prevention and shock absorption.

In order to attain the best performance of the WTGS at the selected wind site,
the setting angle of blade is adjusted through the kidney-shaped hole at end
face of hub so that the force output of the WTGS is the best under certain
conditions (altitude, annual average wind speed etc).

Manhole and maintenance platform are set on hub. Because the distance from hub
manhole to nacelle cover opening is short, it is easy for operators to go into
hub for maintenance. However, with concern for safety, hub is locked during
operation out of nacelle to guard the safety of operators in the nacelle.

2.3 Gearbox

The gearbox is designed as a speed increasing box to converting the low speed
rotation of blade to high speed rotation suitable for generating electricity.
The gearbox construction applies the integrated main shaft design containing
main shaft and main bearing inside. Being contained inside the gearbox, the
lubricating conditions of the main bearing is greatly improved with stronger
ability to withstand severe weather.

The gearbox is fixed by the flange connection at end face and with splash
lubrication inside. In addition to lubrication, the lubricating oil also brings
heat to gearbox outside and then through the heat exchanger on the lubrication
station to the cooling liquid.

The gearbox is equipped with lubricating oil and high-speed bearing temperature
sensors, which are able to indicate oil temperature and shut down wind turbine
generator if the oil temperature is too high. The sensors are to measure oil box
temperature and high-speed bearing temperature. Two sets of heating devices for
preheating the lubricating oil in cold days are mounted at the oil box.

2.4 High-speed Shaft & Mechanical Brake

A brake disc and two floating brake calipers are mounted on the high speed
shaft. Two brake calipers use asbestos-free brake pad. When the hydraulic device
(passive system) is released, the brake pad is closed by spring. The wear and
failure of brake pad is monitored and controlled by the control system. The
brake system shall take measures against oil leak and fire.
  
 
51

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

 
2.5 Bedplate and Support Structure

Support structure and bedplate are welded by Q345E steel plates, which can
guarantee the mechanical properties needed by design at -40℃.

Support structure is an important structural component in the drive chain to
connect gearbox and generator. The gearbox is flange connected to the front end
of support structure and the generator is connected to the back end. The lower
end of support structure connects the bedplate through elastic materials that
are used for shock absorption and prevent the vibration transmitted from gearbox
and generator to bedplate and tower. Or else, noise will be produced.

Manhole is opened at the bottom of support structure for maintenance personnel
to maintain the support structure. Ladder and manhole leading to nacelle are
designed on the bedplate where maintenance personnel can maintain the yawing
drive system (yawing gear and yawing gearbox etc).

2.6 Nacelle

Nacelle is made of fiber glass reinforced polyester resin and connected in upper
and lower halves. A large enough space is reserved for the maintenance personnel
so as to provide convenience for maintenance.

A heat exchanger is mounted at the top of nacelle to bring heat of cooling
system to atmosphere through high speed air flow at nacelle top. Two sets of
anemometer and dogvane with automatic heating function are installed at the
external top of nacelle. These equipments can be maintained through the nacelle
door (safety protection measures provided for repair outside the nacelle).

A tying point of safety rope is set up in the nacelle (including tying point of
safety rope for entering nacelle and going to top) so that maintenance personnel
can conveniently work outside the nacelle.

The nacelle is well sealed to prevent sand and dusts, with reliable rain and
moisture proof.

2.7 Yawing System

The yawing system is driven by a hydraulic motor and engaged with yawing gear by
internal engagement to realize upwind operation. There are three sets of yawing
drive systems (including hydraulic motor and reduction box).

The yawing system isn’t configured with yawing brake, so under both operating
conditions, either yawing or unyawing, the yawing system will drive the nacelle
for small sway with damping. Only when there is need for maintenance, the yawing
system will be completely locked and unmoved. The purpose of this design is to
reduce the fatigue load at tower top as possible.

The yawing system has the automatic unwrapping function. The condition setting
of the yaw counter allows automatic unwrapping and resetting after cable
wrapping and the system is set with a cable wrapping protection system. Once the
automatic unwrapping function fails and it wraps to some extent, the wrapping
protection device sends out accident signal to emergently stop the system.

Electricity is transmitted to tower bottom through low-temperature-torsioned
flexible cable.

2.9 Tower

Tower is welded by steel plates. Maintenance personnel enter from the door on
the ground. Vertical ladder is mounted inside the tower with safe and reliable
handrail and boosting device. The tower surface is sand blasting cleaned and
paints the anticorrosion coating with the same color as the blades.

Different heights of towers are configured according to site conditions so as to
adapt to island, waters bank and offshore situations.

2.10 Control System

The control system is an embedded system based on microprocessor, which controls
the operation of the WTGS, standstill or idling of wind turbine generator at
gentle wind, conversion to generator at normal rotation speed, adjustment of
generator towards wind direction, unwrapping (by rotating nacelle), all
functions and shutdown of wind turbine in case of emergencies or strong wind.
The communication with the wind turbine control system can be transmitted
through optical fiber (the mode of the control system needs being determined).
  
 
53

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

 
If the brake torque of the generator disappears, such as failure of electrical
components or fluctuations of power grid, the wind turbine will quickly
accelerates to high rotation speed. The control system can safely handle these
situations and brake by complicated steps. It gives the instructions of
emergency stop when failure occurs to certain level of parameters, such as power
grid voltage (failure), rotation speed, power, temperature, vibration etc.
“Watchdog” function is applied for emergency stop at the time of control system
failure. The control system releases the hydraulic cylinder pressure at blade
top by cutting off the electricity supply of the hydraulic electromagnetic
valve. The tip spoiler acts by centrifugal force, and the mechanical brake
caliper acts by the mechanical spring. When the power grid fails, the brake
starts due to loss of power. Any action of mechanical brake or tip spoiler is
able to reduce the wind turbine generator to a safely low rotation speed.

The final safety measure is to provide a safety valve in the hydraulic
components of hub. If the hydraulic pressure is too high, oil in the oil
cylinder at blade tip and now the wind turbine is over-speed. And then wind
turbine rotation speed decreases by the tip spoiler.

The wind turbine shall be provided with the LVRT (low voltage ride-through)
function which prevents wind turbine from being switched off while the power
grid voltage is fluctuating. The brake system of the wind turbine shall have
complete oil leak and fire prevention measures.

The control system shall have a perfect network function, be able to meet the
communication protocol of the dispatching system, and attain bidirectional data
transmission with the dispatching system.

2.11 Hydraulic System

The hydraulic system mainly comprises hydraulic pump station, oil circuit,
control components and actuator, as the power for the brake system. The brake
device is mounted on the high speed shaft. The materials of brake disc conform
to low temperature conditions and is conducted with the dynamic balance test
before ex-factory. Two sets of independent brake systems are provided for the
WTGS to stop the wind turbine generator under any conditions (including load
rejection of power grid) and when the rotor reaches the largest rotation speed.
The tip spoiler operates under aerodynamic principles and directly acts on the
blades.

6.
Reliability Operation

After commissioning, 240 hours’ reliability operation is conducted when the
operating conditions are met.

The standard of reliability operation is that single wind generator runs
consecutively, stably, safely and unfailingly for 240 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.

In addition, the shutdown caused by the following causes will not be deemed as
wind turbine generator failures:

 
·
Power grid failure (power grid parameter out of the scope of technical
specification)

 
·
Weather conditions (including wind conditions and ambient temperature) exceed
the running scope of technical specification

During the reliability operation period, the accumulative power generation time
of the WTGS shall not be less than 240 hours. If the hour limit is not met, the
reliability operation will continue to reach the accumulative power generation
time 240 hours. If rated wind speed occurs in the reliability operation period,
the generator system shall achieve the rated output; if not, the trial run will
extend 120 hours. Either the accumulative power generation time evaluation or
the rated operating conditions evaluation, the lasting time shall not exceed 240
hours. During the extended running time, if either of accumulative power
generation time and rated output is met, the reliability operation will be
deemed as conformable. If the accumulative power generation time can’t be
achieved due to wind conditions, or rated wind speed doesn’t appear, if the
generator system runs normally without failure during the reliability operation
period, it will be deemed conformable.
 
 
74

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

 
 
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.

After each set passes consecutive 240-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.

2. Calculation and Evaluation Methods of Wind Turbine Power Curve & Availability

Evaluation of equipment availability within the quality warranty period

In the quality warranty period, the seller provides high quality services and
maintenance. The equipment availability evaluation indicator is: in the quality
warranty period as from the date of producing the pre-acceptance certificate.

The availability of any single generator in the wind farm shall be ≥95%.

In case the indicator is not met, reevaluate after at most 3 months’ extension
until meeting the evaluation indicator. The seller shall be responsible for the
cost during the extension period. If it is still non-conformable, the seller
will be deemed as breach of contract and shall compensate related losses of the
buyer.

Evaluation of power curve
 
The sellers provides the standard power curve and the guaranteed power curve
under air density of wind site and promises that the power curves are true and
correct. It is the seller’s responsibility to ensure that the power curves
accord with the technical agreement and contract. The guaranteed power curve
under air density of wind site provided by the seller shall not have an error
larger than ±5% with the actually measured power curve at site. If the
requirements of the technical agreement are not met, it will be deemed as breach
of contract. The evaluation indicator of the power curve within the quality
warranty period is:

Guaranteed value of power curve of a single generator system shall be ≥95%.

The calculation method of availability and power curve characteristics is as
follows:

Guarantee and evaluation of wind turbine power curve

Within the quality warranty period, the buyer can designate a test period for
power curve according to wind conditions on site and production and operation
situations. In the test period, the power curves of each set wind turbine
recorded in the central monitoring and control system of the wind turbine
generator system are evaluated. In order to ensure sufficient and timely
measurement of the complete wind speed sequence of the power curves, the test
period shall not be shorter than 3 months. If the wind conditions for rated
output don’t appear in 3 months, the test period can be extended, but not longer
than 6 months. If the wind conditions don’t appear, extrapolation method is used
as per IEC 61400-12.

In the event that the central monitoring and control system can only plot the
power curve in the accumulative operation period and don’t support the plotting
of power curves at any evaluation period, the buyer shall have the right to
entrust an internationally-recognized test institute or that accepted by General
Administration of Quality Supervision, Inspection and Quarantine of PRC and
select two representative generators which meet testing conditions of IEC
61400-12, to measure the power curves of IEC 61400-12. The guaranteed value of
the minimum power curve of two sets evaluation generators are taken as the
guaranteed values of other generators in the whole wind farm.

 
77

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

 

Even if the central monitoring and control system supports the plotting of power
curves at any evaluation period, the buyer still has the right to entrust an
internationally-recognized test institute or that accepted by General
Administration of Quality Supervision, Inspection and Quarantine of PRC and
select any generators which meet testing conditions of IEC 61400-12, to measure
the power curves of IEC 61400-12 as a substitute for the power curves recorded
by the central monitoring and control system in the same period for evaluation.
Then, the buyer will compare the guaranteed value of actually measured power
curves with that of the power curves recorded by the central monitoring and
control system. If the guaranteed value of power curves recorded exceeds more
than 5% of that of actually measured power curves, the power curves recorded
will be deemed as existing big deviation and the buyer will modify the
guaranteed value of power curves for each set of wind turbine pursuant to this
deviation.

If the wind turbine generator system can’t reach the guaranteed value, the
seller shall adjust the generator system within one month and at most three
months. After adjustment, re-measure again and the measured power curves will be
regarded as the final curves. If it is conformable in measurement after
adjustment, the seller shall compensate for the electric quantity loss during
the period from when the generator is put into operation to the time when it
conforms to the requirements after adjustment. If it remains non-conformable
after adjustment, the power curve of this generator is recognized as
non-conformity in the evaluation and the seller shall compensate for the
electric quantity loss during the whole lifecycle of the wind farm.

1) The guaranteed value of the power curves of the generator is calculated by:

Guaranteed value of actual measurement = (converted power generation in a
typical year / guaranteed power generation in a typical year) × 100%

Where:

Converted power generation in a typical year = feasible wind frequency
distribution of hub height in a typical year × measured power curve value under
feasible air density

Guaranteed power generation in a typical year = feasible wind frequency
distribution of hub height in a typical year × guaranteed power curve value

Measured power curve value under feasible air density: refers to the power
curves obtained by converting the measured power curve from average air density
during evaluation to feasible air density according to the conversion method of
air density in IEC 61400-12.

Guaranteed power curve value: refers to the power curve under the feasible air
density affirmed by the seller in the technical agreement.

2) The electric quantity loss for the generator conformable after adjustment is
calculated by:

Electric quantity loss for the generator conformable after adjustment = average
measured power generation of generators in the same unit (excluding the
evaluated generators) during compensation period × (guaranteed value of
generator’s power curve/ actually measured value –1)

Where:

Generators in the same unit: refers to all other generators in the same
collection line of the evaluated generator

 
78

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

 
 
Compensation period: refers to the whole period from when the generator is put
into operation to the time when it conforms to the requirements after
adjustment.

Measured power generation: shall be the power generation recorded in the central
monitoring and control system of the wind farm

3) Electric quantity loss of the finally non-conformable generator in the
lifecycle of wind farm is calculated by:

Electric quantity loss of the finally non-conformable generator in the lifecycle
of wind farm = grid power generation of wind farm in any whole year (may be
different from a calendar year) including the evaluation period / sets of wind
turbines running this period × (guaranteed value of generator’s power curve/
actually measured value –1) × lifecycle of wind farm

Where:

Grid power generation of wind farm: adopts the reading on the electricity meter
at grid gateway of wind farm.

Guaranteed value of generator’s power curve: 95%

Lifecycle of wind farm: 20 years

The availability of wind turbine generator system is calculated as follows.

The availability of wind turbine generator system is evaluated by year and the
evaluation year may be different from a calendar year.

a) Availability of a single set of generator = [1－(A+B-40-C) / (8760-C)] ×100%

Where:

A refers to failure shutdown hours

B indicates maintenance and repair shutdown hours (every year each wind turbine
has no more than 40 hours of reasonable periodical maintenance time)

C denotes the shutdown hours due to non-seller’s reasons, including:
 
 
·
Power grid cutoff and failure except the normal power grid parameters

 
·
Power blackout in plan

 
·
Failures of main transformer (if covered in the scope of supply of the buyer)

 
·
Maintenance work (at most 40 hours/year)

 
·
Examination or expert study required by the buyer

 
·
Measurement proposed or required by the buyer

 
·
Wind turbine generator shutdown for official requirements (such as noise level,
flickering shadow)

 
·
Icing

 
·
Wind speed lower than cut-in wind speed

 
·
Wind speed higher than cut-out wind speed

 
·
Shutdown caused by the buyer’s reasons

 
·
Shutdown caused by the remote communication problems which is the responsibility
of the buyer

 
79

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

 
 
·
Lightning

 
·
Deliberate or malicious damage

 
·
Windstorm

 
·
Environmental conditions not covered in the “wind site weather” documents

 
·
Theft and steal

 
·
Whether announce or not, strike, insurrection, domestic unrest and civil war

 
·
Earthquake, flood

 
·
External fire and explosion

 
·
Impact and collision by aircraft or other falling objects

 
·
Cable unwrapping

 
·
System automatic inspection

 
If two or more above-mentioned situations occur, the situation with longer
duration will be counted.

b) Electric quantity loss of non-conformable availability = actual power
generation in the evaluation year × (guaranteed value of availability / actual
availability -1)

Where:

Actual power generation in the evaluation year: The evaluation year may be
different from a calendar year. The actual power generation shall be the power
generation recorded in the central monitoring and control system of the wind
farm.

Guaranteed value of generator’s availability: 95%
