Abstract：Because of its high energy saving and high power factor, permanent magnet synchronous motors (PMSMs) have received extensive attention in the traction system of rail transit. For the short distance between the stations, the traction train starts and the brakes are frequently in operation, which wastes a lot of energy and makes the traction network pressure unstable. The coordination strategy of vehicle supercapacitor energy storage system and PMSM is proposed. The vector control strategy of the motor is used to build a supercapacitor and permanent magnet motor simulation platform. The simulation experiment is carried out according to the traction characteristics of rail transit. The results show that the control strategy has superior speed control performance, which starts fast and meets the running requirements of the train. This strategy has a stable network pressure and recovers energy effects.
