2kw 3kw 5kw 10kw pitch controlled wind turbine, centrifugal pitch controlled mechanism of Wind turbine adjusts blade pitch following wind rotor rotating speed, and keep wind turbine at rated rotating speed. The wind turbine has a stable output power and safe running and is maintenance free. Wind rotor never goes to over speed even encounter to variable wind speed and strong gale.
Low wind speed start up, pitch regulation, safe system
Pitch controlled element
Rotating speed change of wind rotor drives the centrifugal pitch control mechanism to adjust blade pitch; wind pressure on wind rotor will reduce, and then wind turbine rotating speed slow down. Close loop control, reliable regulation.
Pitch control mechanism is sensitive, reliable, and can be used in variable environments.
Wind turbine start up: keep a big blade pitch, start up with 2m/s wind speed;
Wind turbine start to run: reduce blade pitch step by step, better for speedup;
4-12m/s wind speed: regulate the optimum blade pitch to keep the max output power of wind turbine;
Encountering to strong wind: adjust blade pitch into negative angle to keep rotating speed within limits;
Manual stop: operate manual winch to adjust blade pitch into negative angle, blade will lose it aerodynamics, start mechanical brake to stop wind turbine.

2kw 3kw 5kw 10kw pitch controlled wind turbine advantages
1. Leading centrifugal pitch control technology
5kw pitch controlled wind turbine, centrifugal pitch controlled mechanism of Wind turbine adjusts blade pitch following wind rotor rotating speed, and keep wind turbine at rated rotating speed. The wind turbine has a stable output power and safe running and is maintenance free.
2. Auto protection system: APS System
Auto protection system, is selfdeveloped system. When wind speed is over 30m/s or output votlage is over rated, protection system will stop wind turbine, when wind speed is suitable, it will release wind turbine again
3. Blade technology:
Choose aerofoil through wind tunnel test, optimize design according to aerodynamics, self design and manufactured blade. 5kw wind turbine blade has high efficiency and wide TSR. It is approved by relating dept and all of the users.
4. Generator technology:
Direct drive, wind rotor matches PM generator in optimum TSR High efficiency, low start-up torque.
Allow continuous running in over speed and over load condition 1.5 times of rated speed and power
Maintenance free
5. Installation technology:
tilt-up tower, particular patent technology, save installation cost
6. 30% more electricity generated
5kw pitch controlled wind turbine double-grade pitch controlled system not only guarantees optimum efficiency of wind rotor, wind turbine safety and steady output power when the wind speed is higher than rated wind speed, but also makes sure the system can trace the optimum tip speed ratio when the wind speed is lower than rated wind speed to make the wind turbine easy startup, good wind rotor efficiency and more power generation at low wind speed zone.
7. Multiple protection measures
Leading eadge protection finishing:reduce 10% wind rotor noise, good anti-corrosion capability, prolong service life effectively
Production Capacity: 2000 sets per year
