摘要

许多PSS调谐方法都只是为了改善机电模态阻尼。在本文中，将整定准则扩展到考虑激励与PSS之间的反应以及多个PSS之间的相互作用所引起的不稳定性。利用灵敏度分析工具对PSS进行调优，当灵敏度系数接近于零时，调优值为最优。单个PSS的设计准则是最大化区域间模式，同时保持恒定的PSS激励不稳定性增益裕度。然而，在多pss设计中，由于pss之间的额外交互作用，标准略有修改。

PSS design for multi-area system based on combined sensitivity concept

Many PSS tuning methods have been addressed to improve the electromechanical mode damping only. In this paper, the tuning criteria are extended to take into account the instabilities due to the reaction between the excitation and PSS, as well as the interaction between multi-PSSs. The analytical tool of sensitivity has been exploited for the PSS tuning and the settings are optimal if the sensitivity coefficient is approaching zero. The design criteria of a single PSS are to maximize the interarea mode whilst keeping a constant gain margin for the PSS-excitation instability. However, in the multi-PSS design, the criteria are slightly modified because of the additional interaction between the PSSs.
