摘要
提出了适用于非直接接地系统中发生单相接地故障时检出接地故障线路的一种新方法———零序电容电流补偿法。理论分析和仿真结果表明 ,该方法适用于中性点不接地或经消弧线圈接地系统 ,具有简单可靠和灵敏性好的特点。
A new method for detecting single phase to ground fault line in non solidly grounded networks--zero sequence capacitance current compensation method is presented in the paper.Theoretical analysis and simulation result have shown that the method can be successfully used in isolated neutral network or a network grounded with a neutral compensator coil.This method is easily implemented in a microprocessor based relay with high reliability and sensitivity.
