Abstract
A wind turbine includes a rotor having a hub, at least one rotor blade coupled to the hub, and a rotor shaft coupled to said hub for rotation therewith. The wind turbine also includes an electrical generator coupled to the rotor shaft, and a generator-side frequency converter electrically coupled to the electrical generator for converting variable frequency AC received from the electrical generator into DC. The generator-side frequency converter is electrically coupled to an electrical load and is configured to at least one of supply reactive power to the electrical load and absorb reactive power from the electrical load. The wind turbine also includes a grid-side frequency converter electrically coupled to the generator-side frequency converter for converting DC received from the generator-side frequency converter into fixed frequency AC. The grid-side frequency converter is electrically coupled to the electrical load and is configured to at least one of supply reactive power to the electrical load or absorb reactive power from the electrical load.
