| 摘要: |
| 提出了适用于同塔双回线的并联电抗器补偿方案,解决了传统的两回线独立补偿方式下存在的补偿度受限,跨线故障时跳开相恢复电压很高,不利于潜供电弧熄灭等问题.研究了传统补偿方式下的并联电抗器补偿度及中性点小电抗大小的取值范围及选择方法.基于对线路恢复电压的分析,提出了双回线综合补偿方案.理论分析和仿真表明,提出的补偿方式可以实现理想补偿度的选择,并且在各种故障类型下都能起到显著降低线路跳开相的恢复电压和加速电弧熄灭的作用,有利于成功实现重合闸.给出了各种补偿方式下并联电抗器参数选择方法和中性点小电抗的最大耐受电压计算方法. |

| Abstract: |
| The independent compensation schemes for dual lines have limited compensation degree,higher recovery voltage and difficult secondary arc elimination,for which,a shunt reactor compensation scheme for dual parallel transmission lines on the same tower is presented.The shunt reactor compensation degree under traditional compensation mode is analyzed and the range of neutral point small reactor and its selection are discussed.The integrated compensation scheme for dual parallel transmission lines is proposed ba... |
| Key words: dual parallel lines on the same tower shunt reactor recovery voltage compensation scheme withstand voltage |
