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°C~40°C and the survival temperature of -40°C~50°C. 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°C, 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°C. The mixture of water and glycol with the proportion of 45%/55% is filled into the cooling system to prevent icing at -40°C. The lubricating oil system of the main gearbox is equipped with oil heater which will automatically start at a temperature lower than -5°C.

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°C.

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°C.

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.

 

2.12 Lightning Protection System

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

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.
