摘　　要："十二五"期间,随着750 kV网络的建设和发展,陕西电网中出现了多处750 kV和330 kV电磁环网,电源点增加和环网运行必然会使电网的短路电流增大,导致部分330 kV和110 kV母线短路电流超标或接近超标。结合咸阳地区电网"十二五"规划,对2012年、2013年、2015年110 kV及以上电网进行短路计算,以研究咸阳地区电网在2012～2015年间需重点关注短路电流超标或接近超标的变电站及其母线,为2012—2015年间电网建设改造提供依据。With the construction and development of 750 kV network in Shaanxi power grid during the 12th five-year plan, various 750 kV and 330 kV electromagnetic ring power point increase and the running of the ring network is bound to cause the power grid short-circuit current increases, and that make some 330 kV and 110 kV busbar short-circuit current are over the limit or close to over the limit. Combined with the 12th five-year plan of Xianyang region grid, this paper carries out the short circuit calculation of 110kV and above in 2012,2013,2015, and analyzes the substation and busbar that should focus on excessive or near excessive shortcircuit current in Xianyang region grid in 2012,2013,2015.
