航空开绕组永磁电机多端口起动发电和储能一体化系统研究OA

With the advancement of more/all electric aircraft technology,onboard electrical systems are progressively evolving towards integration,which imposes requirements for multi-port and multi-directional power flow capabilities in starter-generator systems.This paper proposes an aircraft integrated starting,generation and storage system based on the open-winding permanent magnet synchronous motor(OW-PMSM),due to the multiport structure of OW-PMSM,the one port of the open-winding is connected to the battery through an inverter,while the other port is connected to the load via a rectifier,the starting,generation and storage function could be integrated by the switch.The corresponding operation principle and characteristics are analyzed in detail,and the control strategy for the optimal operating point tracking and power flowing are achieved,and the validity of the proposed control strategy and the feasibility of multi-port power flowing control have been verified by the simulation and experiment results.The integrated starting,generation and storage system proposed in this paper achieves a highly integrated designs,representing significant importance for breakthroughs in key technologies of more-electric aircraft electrical systems.
