对配电网单相接地故障的技术研究

Distribution network single phase to ground fault

中性点非有效接地系统发生单相接地故障时的自动选线技术,一直是配电系统中的难题之一,也是现场运行的薄弱环节之一。为了能够有效地解决配电网单相接地故障的选线问题,确保电网能够安全可靠的运行,文章对基于多判据综合比较的单相接地选线技术进行分析。

Neutral non-effectively grounded system occurred when the single-phase ground fault line selection, has been one of the problems in the power distribution system, one of the weak links in the site running. In order to effectively solve the problem of the distribution network of single-phase ground fault line selection to ensure safe and reliable grid run, post analysis based on multi-criteria integrated single phase earth selecting technology.
