近年来,电力企业为有效地提高电网运行的可靠性,均积极采用配电自动化系统。而在整个配网故障中,单相接地故障的发生几率较高。为此,准确对这类故障进行定位对于确保配网可靠运行具有十分重要的意义。基于此点,首先对配电自动化系统进行概述,并在此基础上对配电自动化系统单相接地故障定位进行系统分析。
In recent years, power companies to effectively improve the reliability of grid operation, are actively using distribution automation system. In the entire distribution network fault, single-phase ground fault probability is higher. To this end, accurate positioning of such failures for the distribution network to ensure the reliable operation is of great significance. Based on this point, the dissertation summarizes the distribution automation system firstly, and on this basis, analyzes the single-phase grounding fault location of distribution automation system systematically.
