最少拍环网控制系统

给出了一种基于重合次数最少、快速隔离故障段线路的10kV配电网线路保护模式,即最少拍环网控制系统模式。该模式适用于绝大多数带辐射分支的环网控制系统,具有开关动作次数最少、对线路的冲击最小、快速隔离故障段线路、自动恢复非故障段线路供电的优点。分析了即使在三相“完全”短路,某控制器检测失误时最少拍的保护过程,提出了最少拍环网供电模式的一组参考参数,叙述了电压型保护模式和电流型保护模式的故障隔离过程,指出了其优点和不足。

Least Beating Loop Network Control System

A new type of distribution line protection mode for 10 kV power supply network--least beating loop network control system mode is introduced in this paper. This mode is suitable for most of loop network system with radiation branches. It has some advantages of minimum switching numbers of operation, minimal shock on the distribution line, rapid isolation from the failure segment, and automatic energization of the healthy segment, some typical protection processes are analyzed, etc..
