China AH-5kW off grid type free energy windmills
ANE wind turbine advantages
1. Leading centrifugal pitch control technology
Anhua pitch controlled wind turbine, is a patented product and pioneer in China. 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
2. Auto protection system: APS System
Anhua 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 vAnhua wind turbine blade has high efficiency and wide TSR. ANE blade has passed the strict test in Denmark, and has got Danish proval.
4. Generator technology:
Direct drive, wind rotor matches PM generator in optimum TSR vHigh efficiency, low start-up torque.
Allow continuous running in over speed and over load condition 1.5 times of rated speed and power
ANE generator has passed the strict test in Germany. Output power, current and voltage all meet design requirements
5. Installation technology:
tilt-up tower, particular patent technology, save installation cost
6. 30% more electricity generated
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.
7. Multiple protection measures
Leading eadge protection finishing:reduce 10% wind rotor noise, good anti-corrosion capability, prolong service life effectively.
Perfect wind turbine breath system, let the air flow easily inside wind turbine, avoid generation of condensated water to protect inner component.
