摘要： A wind turbine generator (10) system is provided. The system includes a generator (24) comprising a rotor (14) and a stator, the generator configured to generate electricity at a first power factor in a first mode of operation and to generate electricity at a second power factor in a second mode of operation wherein the second power factor is greater than the first power factor. The system further includes a power converter (404) electrically coupled to the rotor, the power converter configured to convert the electricity from the rotor to direct current (DC) electricity above a synchronous speed of the generator. The power converter is also configured to supply electricity to the rotor below the synchronous speed. The power converter is further configured to convert electricity at a third power factor in the first mode of operation and to convert electricity at a fourth power factor in the second mode of operation wherein the fourth power factor is less than the third power factor such that the power output of the generator system in the second mode of operation is substantially equal to the power output of the generator system in the first mode of operation and the generator currents are facilitated being reduced in the second mode of operation relative to the first mode of operation.
