超高压电网输电通道枢纽变电站大容量SVS应用研究和工程实践

四川洪沟变电站运行的SVS是运行在500 kV输电通道枢纽变电站以提高输电通道输电能力为目地的静止无功补偿系统。在应用研究的角度讨论了与SVS应用有关的研究、设计、设备参数、控制策略、RTDS仿真试验等有关技术问题,介绍了洪沟SVS系统构成、技术特点以及电网大干扰验证的结果,并对项目的经济效益进行了分析。

SVS(Static Var System) of Honggou Substation in Sichuan province is a static var compensator system operating in hub substation of 500kV transmission path for the sake of improving transmission ability.The research,design,equipment parameter,RTDS(real-time digital simulator) simulation test about SVS are discussed.Then the structure and technology characteristics of SVS are introduced as well as the test results of large-disturbance in power grid.At last,the economic benefit of the project is analyzed.
