摘　　要：为了确保电力系统稳定运行,提出了一种静止同步串联补偿器(Static Synchronous Series Compensator,SSSC)的模型,推导了电力系统中加入SSSC模型后的潮流方程,并将其用于计算电压稳定性灵敏度。在此基础上,用灵敏度指标对比计算和分析了SSSC安装前后整个系统的电压稳定性,结果表明,安装SSSC后的电压稳定性灵敏度指标有较大改善。运用电力系统分析工具PSAT2.1.2对WSCC3机9节点系统进行了仿真计算,其结果再次验证了笔者提出的方法正确、有效和可行。In order to guarantee the stable running of electric power system,this paper proposes a static synchronous series compensator model and deduces the power flow equation after SSSC model in brought in,which is applied to calculate the sensitivity of voltage stability.After that,the voltage stability of the whole system before and after SSSC installed is calculated and analyzed by sensitivity index.Result shows a great improvement.The simulated calculation of WSCC3 9 node system is made by PSAT2.1.2.The result once again verifies the correctness,effectiveness and feasibility of this method.
