A variable speed wind turbine is disclosed comprising a turbine rotor that drives an AC induction generator, a power converter that converts the generator output to fixed-frequency AC power, a generator controller, and an inverter controller. The generator controller uses field orientation to regulate either stator currents or voltages to control the torque reacted by the generator. The inverter controller regulates the output currents to supply multi-phase AC power having leading or lagging currents at an angle specified by a power factor control signal...
A variable speed wind turbine comprising: a turbine rotor including at least one blade mounted to a rotatable shaft; a multiphase generator having a stator and a rotor coupled to the turbine shaft for rotation therewith; a power converter including active switches operable for controlling stator electrical quantities for each phase of the generator; torque command means associated with turbine parameter sensors for defining a torque reference signal; and generator controller means coupled to the power converter for controlling the active switches includi...
