电力机车作为牵引网的负载,其产生的谐波会对牵引网造成污染,如果车网关系不匹配,电力机车和牵引网会产生谐振现象,交流电力机车中间直流电压的低频震荡也会引起牵引网电压的震荡,所以电力机车对牵引网电能质量的影响越来越受到重视.介绍了电力机车产生的谐波对牵引网的影响,车网谐振和低频振荡出现时的现象及其解决办法.

Locomotive is the load of power supply network. Power supply network can be polluted by the harmonics produced by locomotive. If it is not match between locomotive and power supply network there will be resonance. Oscillation of low frequency in DC link of locomotive can also cause oscillation between locomo-tive and power supply network. So the effects of locomotive on the quality of electric energ are paid much at-tention. It introduced the impact of locomotive harmonics on traction power supply network, the phenomena and the resolve measures when resonance and low frequency power oscillation between locomotive and power supply network oeeurre.
