苏南UPFC工程保护配合策略研究
|
摘要
统一潮流控制器(UPFC)是一种能够独立、快速、精确、连续控制系统电压和潮流的最新一代柔性交流输电系统装置,为解决城市电网发展受限问题提供了有效手段。文中针对苏南UPFC工程中保护配置展开研究,介绍了UPFC本体保护的三取二功能以及UPFC的重启策略,在继电保护配置情况及动作策略基础上,提出了UPFC本体保护与交流线路、变压器保护等保护的配合策略。并结合500 k V苏州南部电网UPFC工程实时数字仿真(RTDS)与入网系统调试,给出实际保护配合策略的功能和效果,试验结果表明可有效保护UPFC。
As the latest generation of FACTS device,unified power flow controller( UPFC) can control the system voltage and power flow rapidly,precisely and continuously,which provides an effective means to break the restrictions on urban power grid development. The protection configuration of UPFC project is studied in this paper. Firstly,the 2 out of 3 principle of UPFC self-protection is introduced,and then based on protection system configuration and action strategy,the restart strategy and coordination strategy of UPFC self-protection with AC line protection,transformer protection and other protections is proposed.At last,combining with southern Suzhou 500 k V power grid UPFC project RTDS simulation and system commissioning,the function and effects of the actual protection coordination strategy are given,the results show that UPFC can be effectively protected with the coordination strategy.
