典型配网自愈模式对比研究

Comparative Research on Typical Distribution Network Self-healing Modes

配网自愈是指利用自动化装置或系统,监视配电线路的运行状况,及时发现线路故障,诊断出故障区间并将故障区间隔离,自动恢复对非故障区间的供电。文章详细介绍了主站集中型、主站与级差保护协同型、主站与电压–时间/电流协同型、主站与智能分布式协同型四类自愈模式的动作原理及案例、功能要求,并详细对比了四种自愈模式的优缺点。

Distribution network self-healing refers to the use of automation devices or systems to monitor the operating conditions of distribution lines,detect line faults in time,diagnose fault sections and isolate fault sections,and automatically restore power to non-fault sections.This article introduces in detail the operation principles,cases,and functional requirements of the four types of self-healing modes:master station centralized,master station and differential protection coordination type,master station and voltage-time/current coordination type,master station and intelligent distributed coordination type.The advantages and disadvantages of the four self-healing modes are compared in detail.
