5kW wind mills

5kW wind mills
1. Pass EN61400-2
2. Dual protection system
3. Low noise and free maintenance
4. Stable output power
1. 5kW wind mills introduction

1) Pitch controlled technology
Through centifugal pitch controlled mechanism, the system will stall control actively, has big angle for startup(good startup performance) rated wind speed point, zero degree(optimum wind rotor efficiency) over rated wind speed, minus angle(stall actively to wind rotor power for zero) The pitch controlled system closed-loop control according to the wind speed and rotational speed, to make sure the power curve output steady.
2) ASP System ( automatical safety protection system )
Through checking the signal of wind speed and voltage, the ASP will make the wind turbine pitch control and then stop to protect the whole system when the wind speed is more than 25m/s or the voltage is over 600V; when the wind speed is lower than 25m/s, the system will release brake automatically to make the system start working again. Therefore, the system can full use of wind power for power generation; meanwhile, it doesn

t need people on duty to save a lot of labor cost, safe and steady.
3) Generate 30% more electricity than traditional wind turbine
ANE 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.
4) Multiple protection measures to make sure system much safer and more stable.
