2015年山西中部电网220 kV线路潮流分析研究

摘要

指出了中部电网是山西北电南送、西电东送的枢纽通道，2015年大量机组接入中部电网后造成多条220 kV线路N－1潮流过载，严重影响电网安全，深入研究各种运行方式下中部电网的潮流状况，最后提出有效的解决方案，保证中部电网的安全稳定运行。%Shanxi central power grid is the hub of North to South and West to East channel,and N-1 current of multiple 220 kV lines will be overloaded after a large number of units being connected to central power grid in 2015,which will seriously affect the security of power grid. Against the above problems,this paper thoroughly researched central grid tide conditions in various operating modes. Finally, the effective solution is proposed.
