摘要
安徽电网系统发生了一起线路断线加单相接地短路的复杂故障,期间保护全部正确动作。本文详细分析了保护的整个动作逻辑行为,并从系统运行的角度出发对一些新问题展开了新的探索和研究。
A complex fault that was transmission line breakage and a line with a single-phase ground to short-circuit at the same time happened in Anhui power grid system.All Relaying protection operated right while fault.This article detailed analyses the whole process of the protection logic,and presents new exploration and research on some new issues from the angle of system operation.
