Topology structure of duplex-winding asynchronous-motor alternating current and direct current starting power generation system

Abstract

The invention discloses a topology structure of a duplex-winding asynchronous-motor alternating current and direct current starting power generation system, especially relates to the duplex-winding asynchronous-motor alternating current and direct current starting power generation system used for providing power for a multi-electric aircraft and belongs to the alternating current and direct current mixing power generation technology field. The power generation system comprises a duplex-winding asynchronous-motor alternating current power generation unit integrated on a multi-electric engine high voltage shaft, a duplex-winding asynchronous-motor direct current power generation unit integrated on a multi-electric engine low voltage shaft and a starting power generation driving unit possessing two sides of power output terminals. A disadvantage that a multi-electric aircraft power supply has a single form and an electricity demand of aircraft electricity load diversification can be satisfied.

Description

technical field [0001] The invention discloses a topology structure of an AC / DC starting and generating system for a double-winding asynchronous motor, in particular to a double-winding asynchronous motor AC / DC starting and generating system used for power supply of multi-electric aircraft, and belongs to the technical field of AC / DC hybrid power generation. Background technique [0002] Compared with traditional aircraft, multi-electric / all-electric aircraft have the advantages of simple structure, light weight, high reliability and good maintainability. new requirements. In order to meet these requirements, multi-electric motors came into being. The so-called multi-electric engine is to integrate and install the aero generator in the main steam turbine of the engine to form a built-in generator. According to different factors such as size, speed and working environment, the generator can be integrated in the high-voltage shaft or low-pressure shaft of the multi-electric ...
