Version: 1.0

1.0 Design Features

Ghrepower’s 60kW wind system is a gearless, direct drive permanent

magnet wind generator system, is the first ever and only 60kW system with active pitch control in the world. Rated at 60kW @ 10m/s (22.4mph)

FD21-60/10 wind system highlights:

Gearless, Direct Drive, PM generator with Active Pitch Control

First and only active pitch controlled 60kW wind system in the world

Optimized Active Pitch Power Control

Active 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.

SCADA

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.
