摘　　要：随着上海地区电力负荷逐年攀升,某些地区变电容量不足的问题日益凸显,使地区电网的安全运行面临很大压力,为了保证电力负荷的安全供电,对超高压变电站在运行条件下实施改造势在必行。介绍了上海地区负荷增长、电网发展与环保等因素对部分变电站的影响以及变电站在运行条件下改造的必要性,以500kV黄渡站为例,进行了短路电流计算并且对结果进行了分析,同时给出了配电装置改造的建议。With rapid development of economy in shanghai district,the power load increases year after year,and the transformer capacity inefficiency become increasingly acute,exerting great pressure on safe operation of district power network.To solve the problem,it is imperative to enforce EHV Power Station＇s Modification under Operation to ensure the safety of power supplying and to promote further development of shanghai power network.The influences on EHV Power Station under operation is introduced in this paper,which is imposed by certain factors,such as load growth in shanghai district,development of power network,and environment protection,etc.Then take the 500kV Huangdu substation for example,the short circuit current is calculated and its relative result is sized in detail.It is necessary to modify EHV power station under operation.Some advices on power distribution unit＇s modification is illustrated in the paper.
