摘要
分析了谐振接地系统单相接地故障的特点 ,以零序电流的有功功率和 5次谐波功率方向在单相接地故障时的特征为依据 ,设计并实现的基于 PC10 4工控机的新型小电流接地选线系统选线准确率高 ,能区分母线和线路故障。
In this paper, the characteristics of ground fault in resonant grounding system is analyzed. According to the active component of zero sequence current and the power direction of fifth harmonic tuning, a novel device of ground faulted line detection is designed based on the PC104 industrial computer. The accuracy of faulted line detection is obviously improved and bus bar fault is distinguished from line fault.
