| 摘 要： | UPFC作为FACTS设备中功能最强大的一员,既可以控制电压,又可以控制线路潮流功率,并且具有阻尼系统振荡的功能。首先利用Pscad软件包建立了UPFC的动态模型,并分别考虑在系统线路三相故障时未安装UPFC和加入UPFC的情况。研究表明UPFC可以有效减小故障后的电压跌落的幅值,对故障后线路功率具有快速恢复特性。

| Abstract: | UPFC,as one of the most powerful in FACTS devices,can not only control the voltage,but the line flaw power,and serves the function of the damping system oscillation.First,use Pscad software package to set up UPFC a dynamic model.And the conditions for unmounted UPFC and added UPFC should be separately considered when the three-phase fault of the system line happens.The research shows that UPFC can efficiently reduce the amplitude of the voltage drop-off after a fault and is of instaneous recovery characteristic for the line power after the fault. |
