航空用定子双绕组多相异步电机高压直流起动/发电系统基础研究

Starting/generating technology is one of key technologies of more-electric/all-electric aircrafts, and it has been developing fast in recent years. This project proposes a novel dual stator-winding multiphase induction machine high voltage dc starting/generating system for more-electric/all-electric aircrafts, and investigates its several fundamental theories and key technologies. This machine’s rotor is a cage type one, and there are two sets of multiphase windings in its stator. This starting/generating system has many important advantages, such as simple and robust rotor structure, high-speed-running ability, good electromagnetic compatibility, good controllability, high power density, high reliability, easy integration of starting and generating, and so on. This project proposes a topology with integrated double functions of starting and generating, explores the rules of design, control and operation for this system, derive the mathematical model of this machine and system, proposes a comprehensive optimization method of this machine and system, proposes the high-performance starting and generating control technologies, and solves the problems of the integrated control of starting and generating and the smooth transformation from stating to generating. This project can provide a new and alternative solution for aircrafts' starting/generating system for our country.
