AH-10kW pitch controlled wind turbine introduction

AH-10kW pitch controlled wind turbine, newly developed by Qingdao Anhua, is a patented product and pioneer in domestic. The self-developed 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

Characteristics
1. Optimum aerodynamic shape design: high efficiency, low noise.
2. Centrifugal pitch controlled mechanism: 2m/s low wind speed startup; 3-12m/s wind speed, following wind rotor rotate speed to adjust blade angle at optimum TSR, run in high efficiency; over rated wind speed, wind rotor never goes to over speed and has stable control; 3-25m/s wind speed, wind turbine can run smoothly.
3. Direct drive permanent magnet generator, low startup resistance moment, constant running ability of over loading 1.5 times, maintenance free for more than 30000 hour.
4. Safety control: Have aerodynamic brake, electric magnet brake, mechanical brake and manual stop mechanism. Adjust blade tip angle automatically at negative value when encountering strong typhoon and the blade at stalled condition and meanwhile wind rotor rotating speed was controlled and reduced.
5. Sealed slip ring, no cable twist; Carbon brush and slip ring clean; good conductivity of electricity.
6. Streamline design, and good appearance
7. Long acting anticorrosive treats, no corrosion in 15years.

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 turbine start to run: reduce blade pitch step by step, better for speedup; 4-12m/s: 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.
