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 system for controlling a grid connected power generating system is provided. The system includes a wind turbine, a converter, a first controller and a second controller. The wind turbine supplies electrical power to a power grid and the converter couples the wind turbine to the power grid. The first controller calculates voltage commands to emulate a phasor back electromotive force behind an inductance. The controller further generates converter switching commands from the voltage commands. The voltage commands include a voltage magnitude reference and an internal frequency reference calculated from a power imbalance between an active power reference and the electrical power. The second controller is used to limit a converter current.

摘要： A method to balance transformer flux among a plurality of transformers is disclosed. The plurality of transformers is connected to a plurality of converters, each transformer having an associated converter. The method comprises determining a reference flux value, measuring an actual flux value for each transformer, and developing a plurality of voltage command signals in relation to a plurality of variance values between the reference flux value and each actual flux value. In response to the voltage command signals being received at a modulator in signal communication with the plurality of converters, the method proceeds by generating a plurality of switching signals to reduce each of the variance values by making available the plurality of switching signals to each of the associated plurality of converters.
