| 摘 要： | 采用BPA数字仿真法，分别研究了三峡一华东多回直流输电系统在直流线路故障(单、双极闭锁)时的暂态稳定性，以及直流功率提升和切机措施对保持三峡电网暂态稳定性的作用。计算结果表明，2回直流输电线路各自单极闭锁以及葛上直流输电线路双极闭锁时，三峡电网都能保持稳定：三常直流输电线路双极闭锁时，三峡电网必须同时进行直流功率提升和切机才能保持稳定．

| Abstract: | The transient stability of Three Gorges-East China multiple-loop HVDC system under link faults is analyzed with BPA,including single pole blocking and double pole blocking.The measures to keep the system stable by power support and generator trip are studied.Calculative results show that,with single pole blocking of San-Chang or Ge-Shang HVDC link,the system is stable;with double pole blocking of Ge - Shang HVDC link,the system is also stable.While with double pole blocking of San-Chang HVDC link,the system is not stable until DC power support and multiple generator trip are implemented simultaneously. |
