摘要
针对华东电网500kV输电线路热稳定制约输送能力这一突出问题,分析了提高现有输电线路输送容量的方法,并对提高导线允许温度可能出现的问题进行了研究,最后得出在确保线路安全运行的情况下,提高现行线路输送能力是可行的,并介绍了华东电网提高导线输送能力的应用情况。
According to the problem of thermal equih'brium restriction of transmission capacity for 500 kV lines in East China power network, the method for improving transmission capacity of existing transmission lines were analyzed, and the problems for raising allowable temperature of conductor were studied. The conclusion is that it is feasgale to hnprove transmission capacity of existing transmission lines under safety operation condition. The application situation of improving transmission capacity of lines in East China power network is also introduced.
