摘要
统一潮流控制器(UPFC)作为一种典型的FACTS装置,综合了FACTS元件的多种灵活控制手段.文章中通过选取电压稳定灵敏度指标dUL/dQL,对比计算和分析了装设UPFC前后整个系统和UPFC安装节点的灵敏度值,结果表明,UPFC能有效地提高系统的电压稳定性.运用电力系统分析工具PSAT1.3.4对WSCC-3机9节点系统进行仿真计算,结果进一步验证了文中方法的正确性和有效性.
As a typical flexible AC transmission system （FACTS） device, unified power flow controller （UPFC） is a device for flexibly controlling the power flow of transmission line in power systems. A method is p for calculating the sensitivity indexes of voltage stability of power systems in the paper. In the proposed method, the variation of voltage in a node of the power systems is compared with the variation of the reactive power, and the ratio is used as a index for sensitivity analysis of power systems. The WSCC 3-machine and 9-bus system is used as a example, and is simulated in PSAT system, with a good result in correctness and effectiveness.
