摘　　要：风电场静止无功补偿器(SVC)控制器的性能对于大规模风电汇集地区电网的电压质量以及系统运行可靠性有着至关重要的影响。为此,在实时数字仿真器(RTDS)中建立了风电场及晶闸管控制电抗器(TCR)型SVC的实时数字仿真模型,即构成一个闭环测试系统,并对实际SVC控制器装置开展性能测试。测试结果表明:这种基于RTDS的SVC控制器闭环性能检测系统能够较全面地测试SVC控制器的动态特性。测试中发现,部分厂家SVC控制器在信号测量、调节器模型设计、网源协调辅助控制功能和控制切换等多方面仍存在亟待完善和改进的问题。Performances of SVC controllers have critical impacts on voltage quality and operation stability of local grid integrated with large-scale wind power. A digital real-time model is built for power grid connected with wind farms and TCR based SVCs by real-time digital simulator （RTDS）, which constitutes a closed-loop test system, and can carry out the performance tests on actual SVC controllers. The results show that this kind of closed-loop test system is capable of testing SVC controllers＇ dynamic characteristics more comprehensively. And it is found that, for manufacturers, some functions of SVCs, such as signal measurement, regulator model design, coordination of the auxiliary controls and its switching modes still need to be improved and refined.
