摘要
柔性交流输电系统对电力系统暂态的控制作用已被广泛认可,但对统一潮流控制器(UPFC)方面的作用仍需进一步研究。试验主要分析添加UPFC模块后对系统可靠性指标的影响。增加UPFC后可在不增大系统故障电流的情况下改变线路阻抗,验证了UPFC模块容量的大小在一定范围时对系统可靠性的改善,主要是负荷点指标和系统指标的改善。研究表明,使用UPFC可提高电力系统可靠性。
The control function of FACTS to power system transient status has been widely recognized, but the function of UPFC still need to be further researched. The influence of UPFC module on the power system reliability index is analyzed in test. The addition of UPFC can change the line impedance without increasing the system fault current, which verifies that within a certain capacity range UPFC module can improve the system reliability, mainly improving load point and system index. Study result shows that the usage of UPFC can improve power system reliability.
