摘要
展望建设高一级电压输电网络是西北电网发展的必然趋势。论述了全国联网对西北电网电压等级选择的影响、全国电压等级系列问题、电压等级的合理配置问题、电压级差太近给系统运行带来的不利影响，以及网络结构对电压等级选择的影响。提出西北电网高一级电压采用750kV级的优越性。
The construction of higher voltage level power transmission grid is an inexorable trend of northwest power system development. This paper describes the effect of inter-regional interconnection upon the selection of higher voltage level.the problem of voltage level serialization across the country, reasonable disposition of voltage levels, unfavorable effects of closed related voltage level upon system operation, as well as the effect of grid structure upon voltage selection. It also puts forward the priority of adopting 75OkV higher voltage level in northwest power system.
