消弧线圈接地系统参数模式识别故障线路的方法

Parameter Mode Method of Arc Extinguishing Coil Grounding System to Identify Fault Circuit

中性点经消弧线圈接地系统发生单相接地故障时,由于稳态故障电流很小,目前的故障选线理论不能满足故障选线正确性的基本要求。提出一种基于稳态采样数据的对地参数模式识别方法,可以正确识别发生单相接地故障的线路,并进行理论分析、MATLAB仿真及各种试验。试验结果表明,模式识别法能够有效地解决中性点经消弧线圈接地系统发生单相接地故障时的选线问题。

Due to the steady state fault current was very low,the neutral point passed through the arc extinguishing coil grounding system would cause a singe phase grounding fault.Many available fault selection theories could not meet the basic requirements of the fault selection correctness.The paper provided a parameter to ground mode identification method base on the steady state sampling data,which could correctly identify the circuit to cause the single phase grounding fault.The paper had a theoretical analysis,...
