摘要： A pitch control system for a wind turbine is disclosed. The pitch control system may generally include a motor having an armature and a winding and a grid power source configured to supply electrical power to the motor. The pitch control system may also include a plurality of switching components configured to control a first current through the armature independent of a second current through the winding. In addition, the pitch control system may include an auxiliary switching component electrically coupled between the grid power source and at least a portion of the switching components. The auxiliary switching component may be configured to be opened when a grid voltage of the grid power source exceeds a first voltage threshold.

摘要： A system and method for supplying increased frequency supporting current from a doubly fed induction generator (DFIG) to assist in maintaining grid stability is provided. The output capability of a line side converter associated with the DFIG is enhanced by significantly increasing the current handling capacity of electric switches forming the converter. A dynamic brake is also provided across a DC link bus coupling the line side converter to another converter coupled to the rotor of the DFIG. The dynamic brake is controlled based on the voltage across the DC link bus.

摘要： A rotor for a wind turbine generator includes a rotatable hub forming a cavity. A plurality of rotor blades is connected to the hub. A heat sink is at least partially positioned within the cavity and extends along a portion of a corresponding rotor blade. The heat sink includes a bottom surface mounted on a thermal energy generating component of the wind turbine generator. An opposing top planar surface includes a plurality of pins extending therefrom. The pins form an air flow path through the pins to dissipate the generated thermal energy from the thermal energy generating component.
