摘　　要：提出了一种中性点不接地电网单相接地电容电流的实时检测方法，首创动态补偿方法解决补偿电网正常运行时的谐振过电压同单相接地后最佳补偿的矛盾，研制出用于６ｋＶ电网的ＺＤＢ－６／８０成套动态补偿装置。This paper proposes a real-time detecting method for the single-phase groundingcapacitive current of neutral non-grounding network.It initiates a dynamic compensatingmethod,thus meeting the requirements of low resonant overvoltage in normal operation and bestcompensation at single-phase ground fault.A dynamic compensating device is developed.
