摘要：
In view of the power characteristics of the load in the transient state of the electric locomotive (drive in-brake-start), this paper studied the output configuration and control strategy of the transition state of the electrified railway static power conditioner for the first time. The traditional electrified railway static power conditioners usually use a maximum capacity configuration, and the control method is also for the stable operation state of the electric locomotive. The power distribution and control method proposed in this paper is compatible with the power quality, capacity configuration and output demand of the electric locomotive in the transient state operation, which fully exerts the parallel characteristics of the railway power regulator and effectively improves its utilization. Firstly, by analyzing the load power and current characteristics of the traction locomotive in the transient state, it can be known that the traction locomotive load power and current exhibit fluctuation. Then, according to the operating characteristics of the transition state of the electric locomotive, the capacity configuration and output of the electrified railway static power conditioner were allocated to meet the power quality requirements. On this basis, the railway static power conditioner maximum output control strategy of the locomotive transition state was innovatively studied, and then the reasonable electrified railway static power conditioner command current and capacity configuration area was obtained, which solves the situation that the traditional control mode is prone to overcurrent protection and exits, It effectively satisfies the operating environment of the locomotive transition state (such as acceleration), including fluctuation characteristics such as current and power, and realizes the organic unity of power quality of electric locomotive traction and capacity configuration and output of electrified railway static power conditioner. Finally, the effectiveness and rationality of the algorithm were verified by Matlab simulation and experimental platform. © 2020 Chin. Soc. for Elec. Eng.
