摘　　要：介绍500kV电网的运行方式和代表日电网线损理论计算结果,以河北省南部电网为例,分析500kV电网的线路损耗、变压器损耗等各项损耗的构成,并通过与上一年500kV电网各项损耗的对比,指出了500kV电网目前存在的问题,并提出了降损措施。The reduction of power losses could improve the economic and social benefits of power industry,and losses theoretical calculation act as the foundation of the reduction of losses.Based on the result of losses theoretical calculation on representative day,the constitution of line and transformer losses analyzed in this text,the problems of 500 kV network and the measures of reduct losses have also been proposed through the comparation of other companies in this paper.

关 键 词：500KV电网 线路损耗 变压器损耗 降损
