摘要
串补输电线路有发生次同步谐振的潜在危险。灵活交流输电技术被广泛的研究用来抑制电力系统的这一问题,但是对于在国内电网应用较多,且技术成熟的静止无功补偿装置的研究相对较少。本文利用安装在线路中点的静止无功补偿辅助控制装置,缓解次同步谐振,并利用PSCAD/EEMTDC仿真软件在IEEE第一标准测试模型基础上进行仿真测试。
Subsynchronous Resonance(SSR) is a potential problem in power systems having series compensated transmission lines.Flexible AC Transmission Systems(FACTS) Controllers are widely applied to mitigate this problem.However,applications for the use mature technology of static var compensation device was relatively small.In this paper,the use of SVC and Subsynchro-nous Damping Controller installed in the mid-point of lines is proposed to mitigate SSR.The effects of SVC with SSDC mitigate SSR are simulated in time domain by the program PSCAD.
