摘要
提出了一种新的设计多机电力系统中励磁和超导储能装置的分散 L2 增益干扰抑制控制器的方法。文中首先建立了含超导储能装置的多机电力系统的动态模型 ,继而利用递推方法设计励磁和超导储能装置的增益干扰抑制控制器 ,所得控制器可以利用本地测量量实现。计算机仿真结果说明了所设计的控制器可以提高系统的暂态稳定性 ,显著改善系统的动态性能。
A dynamic robust model is established for the m ulti- machine power system including superconducting magnetic energy storage SMES device.In order to enhance the transient stability and to im prove the dynamic performance of the power system,a novel nonlinear robustcontrol design approach is developed for generator excitation and SMES via the back- stepping m ethod,which is one of L2 - gain disturbance attenuate control design m ethod.The controller obtained by the above method just uses decentralized m easurem ent,which makes it practicable.The results of digital simulation m anifest that the proposed excitation and SMES controller works better than the linear optimal excitation and SMES controller or nonlinear robust excitation controller for the purpose mentioned above.
