摘　　要：针对我国首次采用静止无功补偿器(Static Var Compensator,SVC)抑制次同步振荡(Sub-Synchronous Oscillation,SSO)的工程,分析了该工程中SVC的接入位置、触发方式和控制策略等。基于实时数字仿真(Rea Time Digital Simulator,RTDS),搭建了针对该工程中SVC控制器进行闭环控制测试的平台。阐述了该平台的框架结构、硬件配置,分析了建模过程中存在的问题,提出了大型系统的建模方法。基于该平台,在典型运行方式和故障方式下,对SVC抑制SSO的效果进行了全面的验证,并仿真分析了SVC抑制SSO时其对交流系统所可能产生的影响。结果表明,所采用的SVC能够抑制SSO现象,并且对系统的暂态稳定性几乎没有影响。This paper briefly introduces the first project using SVC to mitigate SSO in China in the aspects of access location, trigger mode and control strategy, etc. Based on real time digital simulator, a closed-loop platform is established for testing the SVC controller of this project. The issues about this platform, such as the platform architecture, hardware configuration and model selection of RTDS, are discussed. And a method to build model for large scale network is proposed. Under typical operation mode and fault conditions, the performance of SVC controller is fully validated and its effect on AC system is analyzed. Simulation results show that the SVC used in Jin-Jie power plant can mitigate the SSO phenomenon and will not exert influence on the transient stability of systems.
