摘要
特高压交直流输电线路接入电网后,电压稳定的研究对电网的安全稳定运行十分重要。介绍了基于浙江电网规划数据,采用BPA作为分析软件,计算出浙江电网的潮流分布情况,并对浙江特高压输电线路故障后的暂态稳定性进行仿真。结合稳定曲线分析工具,分析了特高压交直流线路故障对浙江电网暂态电压稳定性的影响,并针对不稳定的情况提出了暂态电压稳定性控制策略。
After UHV AC and DC lines connecting to power grid,the study on the voltage stability is very important for the safe and stable operation of power grid.Based on the planning data of Zhejiang grid,BPA was used as analysis software to calculate the power flow distribution of Zhejiang Grid.The transient stability after a fault of Zhejiang ultra high voltage transmission lines was simulated.Combining with the analysis tool of stability curve,the effects of the UHV AC and DC line fault on the transient voltage stability of Zhejiang grid were analyzed.Aiming at the grid′s instabilities,control strategies of the transient voltage stability were proposed.
