Purchase Contract for Wind Generator Set

The buyer’s Contract No.: KG0809C-FD-PL-J001

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.
