摘要
统一潮流控制器(UPFC)是功能最全面、技术最复杂的柔性交流输电技术,文中在介绍UPFC的技术原理、运行方式等基础上,重点分析了UPFC的换流器技术发展,并介绍了国外UPFC的应用情况和使用背景。文中对南京西环网UPFC示范工程的必要性进行了研究,并详细介绍了工程的接入系统、UPFC拓扑结构、换流器结构、串并联侧接入和直流场方案等,并对工程的综合效益进行了分析,结果表明UPFC技术对于解决南京西环网潮流控制问题具有十分重要的作用。
As the most comprehensive and complicated FACTS technology, unified power flow controller＇s technical principle and operation mode are introduced in this paper. Also the converter technology is detailed analyzed as well as the application and background overboard. This paper also discusses the necessity, system scheme, typical topology, converter access technology and DC field scheme of the UPFC project in Nanjing western power grid. At last, the comprehensive benefits of UPFC are demonstrated. Analysis results show that UPFC plays an important role in solving the power flow control problems facing Nanjing western power grid.
