|
摘要
为提高电力系统的小干扰稳定性,抑制系统中的次同步谐振,研究了多通道次同步附加阻尼控制器之间的协调优化策略。基于模态分离和相位补偿设计了多通道SEDC、TCSC-SSDC和HVDC-SSDC,在充分研究了所有次同步附加阻尼控制器的特点及其适应性的基础上,建立了修改后的IEEE SSR第一标准测试系统,以待改善谐振模式阻尼比最大化为优化目标建立优化模型。利用遗传算法对阻尼控制器参数进行协调优化,以得到能最大程度提高谐振模式阻尼的控制器参数。特征值计算和时域仿真结果表明,经过参数协调优化的多通道附加阻尼控制器能有效地抑制次同步谐振,改善了系统的小干扰稳定性。
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.
