| 摘 要： | 通常考虑输电线路参数的时候认为正、负序互感是可以忽略的.但实际情况中存在强不对称的单回线路和强电耦合的双回同塔线路,这种线路的正、负序之间的耦合能否忽视及其影响大小却少见研究.针对实际线路情况,回顾了输电线路序阻抗理论,建立了输电线路一般的数学模型,推导了更加切合实际的计算公式,给出了线路序电流不平衡度的定义,最后2个... |

| Abstract: | Because the compact double transmission lines on the same tower is hard to exchange phases,and the configuration of conductors and lightning shield conductors has great influence on three phases' charge balance,so the optimization of conductor configuration is necessary.Based on the calculation of charge and system partial capacity of each conductor by surface charge density method,all conductors' position coordinates were treated as variables and were optimized to the basic balance of three phases' charge.... |
| Keywords: | double transmission lines on the same tower compact transmission line surface charge density method working capacitor potential distribution |
