摘要
为解决电气化铁路牵引供电系统以负序为主的电能质量和过分相问题,本文提出一种新型同相供电系统结构,实现了对负序电流的动态抑制,解决了过分相问题,仿真结果验证了该方案的可行性。
In order to solve the power quality problems caused mainly by the negative sequence and phase breaking in traction power supply system of electrified railway, the paper puts forward a new type of co-phase power supply system structure which is able to realize the dynamic suppression of negative sequence current and solve the problem of phase breaking;and the scheme’s feasibility has been verified by the simulation results.
