| 摘 要： | 电网500 kV线路高抗故障率较高,同时电网结构、运行方式变化较快,高抗原始配置条件发生改变。因此对广东500 kV主通道高抗退出可行性及全网选择一组备用高抗进行电磁暂态研究,重点研究线路高抗运行和退出工况下的工频过电压、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,并对系统运行、操作方式提出要求。研究成果对于电网资源综合利用、设备优化配置和节约运行成本意义较大,已实际应用于广东电网,并对全国省级电网具有借鉴价值。 |

| Abstract: | We carried out electromagnetic transient studies on disengaging feasibility and standby applicability of 500 kV HV Reactors in Guangdong main transmission channels,focusing on power frequency over-voltage,switch-on and single-phase reclosing operating over-voltage,secondary-arc currents and recovery voltage,and load rejection operation over voltage when HV Reactors running in and out of working,then put forward requests for system operation and operation mode.The actual application shows that the research f... |
