多通道次同步附加阻尼控制器协调优化策略研究
Coordinative optimization strategy of multi-channel supplementary damping controllers for sub-synchronous resonance
摘要
Abstract
In order to improve small signal stability of power system,and suppress the sub-synchronous resonance (SSR),this paper researches the coordinated optimization strategy among multi-channel sub-synchronous supplement damping controllers (SSDC).Multi-channel SEDC,TCSC-SSDC and HVDC-SSDC are designed based on model separation ideas and principles of phase compensation,on the full study basis of characteristics and adaptability of above all SSDC,the modified IEEE first benchmark model is established for SSR modes,which are selected and to be improved,and the maximized damping ratio under the target mode is taken as the optimization objective and an optimization model is established,the coordinated optimization of damping controller parameters is performed by genetic algorithm to get controller parameters which can maximize damping modes.The simulation results of eigenvalue analysis and EMTDC simulation prove that the parameters in multi-channel damping controllers which use coordinative optimization method are valid for SSR suppression,as well as improve the small signal stability of power system.关键词
