Damping of wind turbine drive train oscillations

摘要

It is described a method and an arrangement for controlling a wind turbine converter (119) having a generator side converter portion (127) and a grid side converter portion (131), the method comprising: determining a damping power signal (P_DTD) based on an actual rotor frequency (Ég); controlling the generator side converter portion (127) and the grid side converter portion (131) based on the damping power signal (P_DTD).
