摘要
文中分析了高压侧故障和负荷的不对称波动,引起中性点电压偏移,对判断谐振接地系统电容电流变化的影响,并提出了准确判断电容电流改变的方法。
This paper analyzes the influence of high-volt- age side fault and asymmetrical fluctuation of load on the judgment of capacitive current change of resonance ground system,and puts forward a method for accurately judging the capacitive current change.
