| 摘 要： | 广东电网500kV惠汕线经茅湖变电站解口后,原线路高压并联电抗器配置条件发生改变,加之电网结构和运行方式变化较快,造成高压并联电抗器故障率较高。为此,对惠汕线惠州、汕头侧高压并联电抗器退出运行展开电磁暂态研究,研究内容包括高压并联电抗器运行和退出工况下工频过电压、合闸及单相重合闸操作过电压、潜供电流和恢复电压以及甩负荷操作过电压等,研究结果表明惠州—茅湖—汕头通道原配置高压并联电抗器退出运行是可行的。 |
| 关 键 词： | 输电线路 高压并联电抗器 电磁暂态 工频过电压 操作过电压 单相重合闸 |

| Abstract: | After 500 kV Huishan line of Guangdong power grid unlocked at Maohu Substation,the failure rate of HV shunt reactors was high due to the change in the original configuration conditions of HV shunt reactors coupled with the rapid variation of power network structure and operation mode.Therefore,this paper carries out electromagnetic transient studies on decommissioning of HV shunt reactors at Shantou and Huizhou ends of the line,covering such aspects as power frequency overvoltage,closing and single-phase re... |
