通过对城市轨道交通牵引供电系统谐波进行分析,对各脉波整流机组的效果进行比较,求解出各脉波整流机组注入电网的谐波电流值,在此基础上提出抑制谐波的解决方法和措施。
By analyzing the harmonics of traction power supply system in urban rail transit, the effects of each pulse rectifier are compared to find out the harmonic current injected into the grid by each pulse rectifier. Based on this, the solution to harmonic suppression is proposed And measures.
