| 摘 要： | 换相失败是高压直流输电技术中逆变器最常见故障之一。以2010华北-华中联网数据为基础，采用PSS／E分析了四川电网故障对宝鸡一德阳规划高压直流项目的换相失败影响，讨论了调整直流系统运行参数以改善换相失败的措施。仿真分析结果表明，四川省内大部分500kV交流短路故障都将导致直流系统换相失败，但故障清除后直流系统均能较快恢复运行，直流系统运行参数对换相失败影响较大。

| Abstract: | Commutation failure is one of the common failures in inverters of HVDC transmission system.According to the data of Northeast China-Central China Power Grid in 2010,the influence the failures of Sichuan Power Grid on the commutation failures of the planning Baoji-Deyang HVDC transmission system is analyzed using PSS/E.Measures of adjusting HVDC operating parameters are discussed to improve the performance of HVDC system during commutation failures.Simulation results show that the Baoji-Deyang HVDC system wi... |
