Abstract: A wind turbine system is provided. In various embodiments, the system includes a nacelle supported by a tower. At least one rotor blade is rotatably connected with the nacelle to capture wind energy. The at least one rotor blade rotates relative to the nacelle for generating electricity. A generator is coupled to the nacelle for converting the wind energy into electrical energy. A transformer-converter assembly comprises a converter and a transformer such that the converter is integrally connected to the transformer. An electrical and control module is electronically coupled to the generator and the transformer-converter assembly.

Abstract: Shorting assemblies, shorting devices, and methods for shorting wind turbine power supplies are provided. A shorting device may include a plurality of cables, each of the plurality of cables including a first end and a second end. The shorting device may further include a plurality of bus bar connectors, each of the plurality of bus bar connectors attached to the first end of one of the plurality of cables and removably connectable to one of the plurality of bus bars. The shorting device may further include a common cable connector, the second end of each of the plurality of cable attached to the common cable connector.

Abstract: An approach for converting a synchronous generator to a synchronous condenser is disclosed. In one aspect, a variable frequency driver is used to provide a starting power source to accelerate a synchronous generator decoupled from a turbine to an operational speed to act as a synchronous condenser. In another aspect, the synchronous condenser can be recoupled back to the turbine to form the synchronous generator.

Abstract: A method for controlling a rotational speed of a rotor having at least one rotor blade, a rotor shaft, and an electrical generator coupled thereto. The method includes controlling a torque of the rotor shaft by controlling a torque of the electrical generator, alternating between changing an angle of pitch of the at least one rotor blade and maintaining the angle of pitch of the at least one rotor blade substantially constant, and maintaining a substantially constant rotational speed of the rotor during variable wind speeds above a predetermined rated wind speed.
