The invention belongs to the field of high-voltage direct-current permanent magnet starting power generation, and particularly relates to a high-voltage direct-current permanent magnet starting power generation system based on double three-phase permanent magnet motors. Comprising a 250V-700V DC starting power supply (1), a first contactor (2), a starting power generation controller (3), a 28V DC bus bar (4), a second contactor (5), a 540V DC high-voltage DC bus bar (6), a 250kW high-voltage DC permanent magnet starting generator (7), a flight control key load (8) and an aero-engine (9). In a starting state, a ground power supply or an onboard storage battery provides a 270V-700V direct-current starting power supply for the public motor starting controller; in a power generation state, an engine drives a rotor of the permanent magnet starting generator to rotate, a magnetic field generated by a small permanent magnet machine rotor on the rotor cuts a small permanent magnet machine stator winding, three-phase alternating current is generated in the small permanent magnet machine stator winding, one path supplies power to a controller, and the other two paths supplies power to an onboard flight control system; and through full-wave rectification regulation and control, the direct current is converted into 540V high-voltage direct current to supply power to related loads on a machine.

    本发明属于高压直流永磁起动发电领域,具体涉及一种基于双三相永磁电机的高压直流永磁起动发电系统。包括:250V至700V DC起动电源(1)、第一接触器(2)、起动发电控制器(3)、28VDC汇流条(4)、第二接触器(5)、540VDC高压直流汇流条(6)、250kW高压直流永磁起动发电机(7)、飞控关键负载(8)、航空发动机(9)。起动状态下,地面电源或机上蓄电池向公共电机起动控制器提供270V~700V直流起动电源;发电状态下,由发动机带动永磁起动发电机转子旋转,转子上的小永磁机转子产生的磁场会切割小永磁机定子绕组,在其中产生三相交流电,其中一路为控制器供电,另外两路为机上飞控系统供电;通过全波整流调节控制,转换为540V高压直流电,为机上相关负载供电。
