摘要： A turbine generator system includes a doubly-fed alternating-current (AC) generator having a first poly-phase circuit (e.g., a stator circuit) and a second poly-phase circuit (e.g., a rotor circuit), a poly-phase AC-to-AC converter circuit coupled between the first and second poly-phase circuits, a poly-phase transformer having input windings coupled to the first poly-phase circuit and having output windings, and a uni-directional rectifier circuit coupled to the output windings of the poly-phase transformer and configured to convert poly-phase AC from the transformer output windings to direct current (DC).

摘要： An aircraft electrical power generation system includes an AC generator having a rotor including a plurality of electromagnetic rotor-windings and stator including plurality of electrical stator-windings. The rotor mechanically coupled to a shaft of a gas turbine engine by transmission-system. The generator includes a frequency controller, a torque sensor determining a torque on the transmission-system by the generator and controller to operate the system in first and second modes. In first mode, the power output frequency of the generator controlled by the frequency controller within limits, and reduced idle signal going to a turbine engine controller. In second mode, the power output frequency of the generator not controlled by the frequency controller and increased idle signal going to the turbine engine controller. The controller operates the system in first mode when the torque is below a limit, and in second mode when the torque is above a limit.

摘要： The present application provides a doubly-fed induction generator system for a multi-shaft gas turbine engine. The doubly-fed induction generator system may include a first doubly-fed induction generator in communication with a first shaft of the multi-shaft gas turbine engine, a first rotor of the first doubly-fed induction generator in communication with a converter via a first rotor bus, and a first breaker on the first rotor bus. The first doubly-fed induction generator acts as a generator or a motor depending in part upon the position of the first breaker.
