太原电网运行方式深入分析及优化

Analysis and Optimization about the Operation Mode of Taiyuan Grid

随着太原电网各220 kV变电站供电负荷的不断增加,在大负荷期间,负载率达到了危险的高度,介绍了此段期间的负荷情况,分析、推算出电网发生主变"N-1"故障后,现运行方式下电网所承载的巨大风险,通过分析、测算、比较,提出了进一步优化运行方式的改进方案。

With the constant increasing load of 220 kV substations in Taiyuan, the load rate will arrive at an astonishing extent during the period of heavy load .This paper analyses this extreme situation and assesses the risk in the case of main transformer break down, which disobeys ＂N-I＂ principle under current grid operation mode. Through analysis, calculation and comparison, the paper further puts forward some optimum proposals as to grid operation mode.
