摘　　要：针对山西中部220 kV双环网中部分厂、站短路电流水平超标或接近断路器额定遮断容量的问题,主要从电网结构来分析,通过必要的电气计算,提出中部220 kV双环网解网的思路和目标。With the continuously increasing of power installation in Shanxi central section and continuous development of Shanxi network, short-circuit lever of some power plants and transformer substations in Shanxi central section has gone beyond or approached rating shutoff capacity of switches, and controlling short-circuit lever has became a important reference guideline in programing and designing project. This article mainly analyses from the structure of grid and studies the thought and aim about unting the 220 kV network in the period of 2006-2010.
