摘　　要：特高压交流输电线路接入安徽电网后,将对安徽电网的安全稳定运行产生重要影响.利用中国电力科学研究院开发的PSD-BPA潮流稳定程序,结合稳定曲线分析工具,对特高压系统对安徽电网潮流和大干扰电压稳定性的影响进行了分析,并对其进行了仿真.仿真结果表明:安徽电网在接入特高压后的潮流分布合理,暂态大干扰稳定性较差,需尽早制定防范预案.When connected to Anhui power grid, the UHV AC lines will have a huge influence on the safe and stable operation of the power grid. PSD-BPA software and stability curve analysis tool developed by China Electrical Institute is used to analyze the influence of UHV-transmission system on power flow and big disturbance voltage stability of Anhui Power Grid. The result of the simulation of the influence indicate that when connected to UHV-transmission system, Anhui Pow- er Grid has a reasonable power flow distribution, but poor big disturbance voltage stability. There- fore, a preventive plan should be constituted as soon as possible.
