A variable speed wind turbine generator system to convert mechanical power into electrical power or energy and to recover the electrical power or energy in the form of three phase alternating current and return the power or energy to a utility or other load with single phase sinusoidal waveform at sixty (60) hertz and unity power factor includes an excitation controller for generating three phase commanded current, a generator, and a zero sequence filter. Each commanded current signal includes two components: a positive sequence variable frequency curren...
[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] Generator apparatus, comprising:a variable speed rotor that is magnetically coupled to a plurality of electrically excited stator windings that are connected together at a common node;filter means connected electrically to at least one of said stator windings for passing current that has a first characteristic and for blocking current that has a second characteristic;a chargeable energy storage device connectable electrically, but not t...
