电力机车辅助电路移相电容控制方法的改进

Improvement of control method of phase shifting capacitor on electric locomotive auxiliary circuit

在电力机车辅助电路移相电容支路中采用串联晶闸管的方法,消除了在合闸瞬间产生的电流冲击。利用PSIM仿真软件进行了仿真实验,在相同的仿真参数下,对比了移相电容支路串联晶闸管前后的功率因数曲线,可以看出,在移向电容支路串联晶闸管后电路的功率因数明显提高。

Used method that shifting phase capacitor series thyristor in electric locomotive auxiliary circuit, eliminates in the closing moments generated current shock. Simulating to use the PSIM simulation software, in the same simulation parameters, contrast the power factor curve using thyristor in the series of shifting phase capacitor, after series of shifting phase capacitor uses thyristor the power factor of the circuit is improved obviously.
