一例典型的阜阳电网运行方式调整及其分析

Adjustment and Analysis of a Typical Case of Operation Mode in Fuyang Grid

阜阳地区500 kV颍州变电站扩建220 kV正午变电站间隔时4条220 kV线路将运行于同一母线,本文介绍和分析了一例为防止发生大面积停电事故的典型运行方式调整案例。针对阜阳电网西断面安全可靠性低、稳定性不足的问题进行运行方式的调整,从而达到最大程度地减少限制负荷量、提高电网安全稳定性的目的。

Four 220 kV lines will running on the same bus when 500 kV Yingzhou substation expands intervals of 220 kV Zhengwu substation in Fuyang area,the paper introduces and analyzes a typical case of operation mode adjustment for preventing large-scale blackout accident Contraposing low safety reliability,poor stability problems in west section of Fuyang grid that adjust operation mode,thus,achieving maximum reduce the load limitations,enhancing the purpose of power grid safety and reliability.
