摘要
以福建电网2008年年底大方式为基础,采用PSD电力系统分析软件对各种故障扰动下福建电网的暂态电压稳定性进行数字仿真计算和分析,模拟了三相故障永久性跳闸、发电机组失磁、两台联变故障、电厂全停等多重故障形式。仿真结果分析表明,该方法研究动态电压特性有效,采取合理的控制措施可提高电网可靠性和系统抗扰动能力。
Based on the typical operating cases of FuJian Power System in 2008, the Static Voltage Stability status have been calculated and the Static Voltage Stability level has been synthetically simulated. Multi-contigencies include three-phase permanent fault tripping of Houxia section and Xiaquan section,loss of generators excitation of HouShi Power Plant. The simulation results of a detailed analysis show that it need to take reasonable measures in the case of the three-phase permanent fault tripping of Houxia section,otherwise there will be rapid internal loss of stability of the accident in Fujian power grid .
