提出采用负序电流及故障点损耗能量进行故障选线的新原理,该原理不受中性点接地方式的影响,适用于中性点不接地配电网、经消弧线圈接地配电网,甚至全补偿运行的配电网,该原理适合就地安装,便于在馈线就地控制终端单元(FTU)上实现.原理已经仿真分析及模拟实验论证.,A new principle for grounding fault feeder detection based on negative sequence current variation and energy dissipated in the fault point is presented. It has high precision in both isolated systems and resonance earthed systems, even in full-compensated systems. And it can be installed at the local control unit of feeder in distribution automation systems, such as field terminal unit (FTU). This principle is verified by EMTP simulator and experimentation. 相似文献
