| 摘 要： | 以锡盟—南京1 000 kV特高压工程为例,借助PSCAD仿真软件研究了输电线路不同情况下的电气不平衡问题。仿真结果表明:输电线路不平衡度随着导线长度的增加而增大,随着输送功率的增加而增大,同时受导线排列方式影响较大。对于1 000 kV锡盟—南京同塔双回输电工程,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 was used to study transmission line unbalance based on 1 000 kV EHV transmission project from Ximeng to Nanjing.The emulation result shows that unbalance level of transmission line is increased with the increasing of length of transmission line or transmission power and is influenced greatly by the arrangement of conductors.By studying,reverse-phase arrangement conductor and reverse transposition method is recommended to gain best effection for 1 000 kV EHV transmission project from Ximeng to Nanjing. |
