摘要
结合特征值分析和蚁群算法寻优对附加励磁阻尼控制器(SupplementaryExcitationDampinController,SEDC)的设计进行了详细探讨。在对SEDC结构和原理进行分析的基础上,建立了含SEDC的IEEE次同步谐振第二标准测试系统小干扰模型。对该模型做特征值分析,并以预设的多种运行状态下模态阻尼最大化为目标函数,运用蚁群算法对控制器参数进行计算和优化。特征值分析和EMTDC仿真结果证明了采用该方法所设计的SEDC具有较强的鲁棒性,能够有效抑制次同步谐振。
This paper investigates a novel strategy to design supplementary excitation damping controller（SEDC） by combining with eigenvalue analysis and ant colony algorithm.Based on the analysis of the structure and principle of the SEDC, small signal model of IEEE second benchmark model for SSR with SEDC is set up.The parameters of SEDC are calculated and optimized by maximizing the real part of eigenvalue of subsynchronous oscillation mode in several operating conditions, and ant colony algorithm is used in this process. The results of eigenvalue analysis and EMTDC simulation prove the robustness of the SEDC and the validity for SSR suppression.
