FD21 50 i d t hi hli ht

Ghrepower’s 50kW wind system is a gearless, direct drive permanent

magnet wind generator system, active pitch control . Rated at 50kW @ 9m/s

(20.1mph)

FD21-50 wind system highlights:

Gearless, Direct Drive, PM generator with Active Pitch Control

High reliable, high efficiency

Optimized Active Pitch Power Control

Active pitch control technology realizes automatic pitch angle adjusting under heavyActive pitch control technology realizes automatic pitch angle adjusting under heavy

wind environment and captures more wind energy in low wind conditions. At the

same time, it ensures a steady power output in heavy wind condition, which allows

Ghrepower to obtain a national technical patent.

Smart Multi-level Protection

Smart pitch control brake, mechanical brake, electromagnetic brake, dump load and

active yaw system are intelligently controlled and adjusted under extremely weather

to ensure wind turbine system protection and parking.

Full Power Inverter with Isolation

Ghrepower's full power inverter converts and transfers unsteady wind energy to

steady AC power of constant frequency and voltage to the grid, and its isolation

isolates grid from the wind turbine to ensure wind turbine safety and minimizes grid

disturbance.

SCADASCADA

Real time and remote monitoring and control of wind turbine operation, on the fly

parameter setting, historical and real time wind data processing and output,

including, but not limited to, wind speed, direction, rotor speed, wind energy

generation etc.
