摘要:

通过对河南电网某220 kV变电站的测试和分析,确认110 kV侧的电力牵引负荷注入电网的谐波电流超标,由于电容器回路的参数配置不当,使电容器中的7次和9次谐波电流均被放大,从而引起电容器频繁烧保险.通过调整电容器回路的参数,降低了谐波电流放大倍数,减少了电容器中的谐波电流,保证了电容器的正常运行.

Abstract:

Through the test and analysis of a 220 kV substation of Henan Power Grid, it is confirmed that the harmonic current injected into the power grid by the electric traction load on the 110 kV side exceeds the standard, and the 7th and 9th harmonic currents in the capacitor are amplified due to improper configuration of the parameters of the capacitor loop, resulting in frequent burning of the capacitor. By adjusting the parameters of the capacitor loop, the harmonic current amplification is reduced, the harmonic current in the capacitor is reduced, and the normal operation of the capacitor is guaranteed.
