20kW wind turbine pitch controlled wind generator for island use

20kW wind turbine pitch controlled wind generator for island use

1. Technical parameters

2. Output power curve

3. Character

a. Remote monitor, automatic yawing, pitch control, ASP protection system, a new quaternary and intellect wind turbine.

(1) Remote monitor

Remote monitor system inspects the wind speed and generator voltage, send order to change the wind turbine stop or run even send order to start up the background power source. This system also sends unusual station and failure parameters to user; improve the user’s emergency capacity and pertinence to debugging.

(2) Automatic yawing

Automatic wind answering system will find the right wind direction according to the inspection to wind speed and wind direction. To make sure a good output power at small wind speed and a good protection at gale. Rotating body is same with MW wind turbines, lower failure rate, and long service life.

(3) Pitch control

Dual pitch controlled mechanism adjust the blade angle according to different wind speed, to make sure wind turbine have output power with smaller wind speed and have a stable output power at gale. Pure mechanism design with rotating speed as the input sources makes soft and exactly regulation.

(4) ASP protection system

ASP, our patent technology, unique product in China will control the wind turbine to stop or work through inspecting environment wind speed and system working voltage. Then the wins peed or voltage is over than set value, system will brakes wind turbine automatic, when wind speed is below than 25m/s, system will release the brake to let equipment work. It makes unattended come true.

b. Variable damp system, high reliable, whole progress pitch controlled,

This system will improve pitch control answering speed by changing the damp in every phase to overcome regulation inaccuracy.

c. Special aerofoil design, high efficiency blade.

d. Generator anti-over current protection technology.

When the output current of generator comes up to rated value, it will not be increased following with the rotating speed. There is not over current even over speed or short circuit.

e. Maximum voltage constant technology.

Combining pitch controlled technology and generator characteristic, this technology insures wind turbine has a stable voltage with maximum output power, wave area is smaller than 2%, improve wind turbine’s resistance to pressure, improve system’s reliable and survive capacity.

4. Application area

Micro grid power station, on-grid system, wind and solar hybrid system, oil plant, communication station, sentry, island, sight lighting and so on.
