摘　　要：针对电力机车分相区时暂态过程对机车及牵引系统造成的不良影响,对机车过分相区时暂态过程进行了分析,并对机车过分相区时可能产生截流过电压及合闸励磁涌流的原因进行了理论研究,提出通过控制机车主断路器的合闸角的技术抑制机车过分相区产生的暂态现象。通过建立电力机车过分相区系统的等效仿真模型,对电力机车主变压器产生的合闸涌流进行了仿真分析,最后的仿真结果验证了理论分析方法的有效性。For electric locomotive passing neutral section system,the magentic transient has adverse effect both on the electric locomotive itself and the traction power system. Three operating conditions resulting from disconnection of main circuit breaker in locomotive over phase zone are analyzed. The reason for the excessive voltage and the inrush current during the over phase area of locomotive is studied. Theoretical a- nalysis shows that by controlling the closing angle of the circuit breaker, transient phenomena can be avoi- ded in the over phase area of the electric locomotive. Using the method,the simulation model of electric lo- comotive transformer for passing neutral section is established,and the simulation results show the effec- tiveness of this method.
