摘要
为解决宁夏电网同塔双回线路存在的零序环流问题,采用电力系统全数字实时仿真方法,对同塔双回线路零序环流进行仿真分析,结果表明:同塔双回不换位导线内零序环流大小与相序布置方式有关,通过改变相序布置可减小零序环流幅值。
In order to solve the problem of zero sequence circular current in the same tower double circuit transmission lines in Ningxia Power Grid, adopts the whole digital real time simulation method to make simulation analysis. The results show that the size of zero sequence circular current is related to the layout mode of the phase sequence inside the Same tower double circuit untransposed transmission lines, through changing phase layout can reduce the amplitude value of zero sequence circular current.
