摘要
750 kV电网已逐渐成为我国西北地区的主力电网,分析了西北地区750 kV电网的发展概况和750 kV线路的电气特性,分析了750 kV线路投运前后甘肃电网网损及网损率、甘肃电网330 kV线损和省际联络线线损,分析结果表明750 kV线路的投运明显降低了甘肃电网损耗。
The 750 kV power network gradually becomes the main power network in Northwest China. The general situation of the development of 750 kV power network in Northwest China are presented and its electrical characteristics are expounded; the network loss and network loss rate of Gansu power grid, the loss of 330 kV transmission lines and the loss of interprovincial tie line before and after putting 750 kV transmission line into operation are analyzed. Analysis results show that the network loss of Gansu power grid is evidently reduced by putting 750 kV transmission line into operation.
