| 摘 要： | 以蒙西—潍坊1000 kV特高压工程为例,借助PSCAD仿真软件研究输电线路的不平衡问题,研究发现,不平衡与输电线路长度、输送功率大小、导线排列方式有关,而解决该问题的有效方法是换位。经过研究,推荐采用逆相序排列、反向换位方式,以实现最优的换位效果。

| Abstract: | PSCAD is used to study transmission line unbalance based on 1000 kV EHV transmission project from Mengxi to Weifang.Depending on the study,unbalance is related to line's length,transmitted power and arrangement of the line.And transposition can effectively settle this problem.By studying,reverse-phase arrangement conductor and reverse transposition method is recommended to gain best effection. |
