摘要
根据陕西电网发展规划,750 kV电网将是未来陕西电网的主网架,它将起到替代330 kV电网输电网的作用。至2015年,陕西750 kV电网将延伸到陕北和陕南,关中地区也有可能形成环网结构。因此陕西750 kV电网和330 kV电网协调发展和运行的问题成为迫切需要解决的问题。本文通过对2010年、2012年和2015年陕西电网短路电流水平的校核,研究陕西电网发展中需重点关注短路电流超标或接近超标的变电站。
According to the development planning of Shaanxi grid, 750 kV grid is used to replace 330 kV transmission network, thus, it is Shaanxi grid main network frame in future. In 2015, 750kV grid will extend to northern ＆southern Shaanxi, and a ring network structure may be formed in Guanzhong area of Shanxi Province. Therefore, the harmonious development ＆ operation of 750kV grid and 330kV grid in Shaanxi is becoming an issue which needs solving urgently. Through the verification of short-circuit current level of Shaanxi grid in 2010, 2012 and 2015, this paper focus on the substation in which short-circuit current level is over standard or is close to over standard in Shaanxi grid development.
