摘　　要：随着经济的高速发展,对供电可靠性有越来越高的要求,配网自愈技术是指利用自动化装置和主站,及时发现故障,通过综合研判各类信号,判断并自动隔离故障区间,通过转电恢复非故障段线路的正常供电。目前常见的自愈类型有三类,本文着重介绍主站与级差保护融合式自愈的原理及其自愈功能调试、投运及运行管理原则。With the rapid economic development,there are increasingly higher requirements for the reliability of power supply.The self-healing technology of the distribution network refers to the use of automatic devices and the master station to detect faults in time,comprehensively study and judge various signals,judge and automatically isolate In the faulted section,the normal power supply of the non-faulty section of the line is restored through power transfer.There are currently three common types of self-healing.This article focuses on the principle of the integrated self-healing of the master station and differential protection and the principles of self-healing function debugging,commissioning and operation management.
