配网自动化系统运行过程中,常见的故障之一就是小电流接地故障,如果不及时采取有效措施预防小电流接地故障,将导致运行能力在整个配网自动化系统中被削弱。鉴于此,本文从小电流接地故障的分段定位原理入手,对小电流接地故障分区定位过程进行阐述,并对配网自动化系统小电流接地故障定位物理模拟展开研究,为我国配网自动化系统的稳定运行奠定良好的基础。
Distribution network automation system operation, one of the common faults is a small current grounding fault, if not timely and effective measures to prevent small current grounding fault, will lead to operational capacity in the entire distribution network automation system has been weakened. In view of this, this paper starts from the principle of sub-locating of small current ground fault, explains the process of sub-locating of small current ground fault, and studies the physical simulation of small current grounding fault locating in distribution network automation system for the stability of distribution network automation system in our country Run to lay a good foundation.
