Power Electronics
The turbine uses a 4Q full power, 3-phase IGBT converter with a rated voltage and frequency of 400 V ±10% and 50-60 Hz ±5%. It supports a power factor range of 0.95 ind - 1 - 0.95 cap for reactive power compensation and grid voltage control. The cooling system is air-cooled for both rotor and stator.

Power Curve
The power curve indicates that the turbine reaches its rated power of 250 kW at a wind speed of 9 m/s and maintains this output up to 25 m/s. The electrical power output increases progressively from 3 kW at 2.5 m/s to 250 kW at 9 m/s.
