摘要
提出"广义单回输电线路"的思路,将同塔双回输电线路的同名相视为一相。以此为基础分析计算了相序排列方式、导线分裂间距、导线分裂数及导线截面等对特高压同塔双回交流输电线路自然功率的影响并提出了导线分裂间距的优化建议。该方法也可扩展到任意多回的情况。
In this paper, we bring out the idea of “generalized single circuit transmission line”——Treating two phases wich have thesame electirc degress as one phase. On the basis of tliis idea, the relationship between the Surge Impedengce Load of UHV AC transmission line and phase arangement, Sub-conductor Bundle Spacing, Sub-conductor Number, Sub-conductor section was calculated and analyzed. The optimization of Sub-conductor Bundle Spacing was also suggested in this passage. Also, this method could be expanded to the situation of multi-circuits on one tower.
