DOUBLY FED INDUCTION GENERATOR WIND POWER GENERATING SYSTEM

摘要

The present invention relates to a DFIG wind power generation system comprising: blades; a drive train having a shaft coupled with the blades and a gear box coupled to the shaft; a converter part having an AC/DC converter and a DC/DC converter; and an output variation compensation control part calculating a damping torque to be applied to the drive train, calculating a compensation current using the size of the calculated damping torque, and transmitting a current compensation control signal corresponding to the calculated compensation current to the converter part.
