摘要
本文根据特征值分析技术,介绍了一种确定多机系统中电力系统稳定器(PSS)安装地点的新方法——D_e 值灵敏度法,用该方法与文献[1]提出的 PSS 参数选择方法相配合,可以成功地解决多机系统中 PSS 之间的协调问题。另外,本文还用该方法与特征向量法作了比较,指出了特征向量法的局限性.模拟研究表明,在小干扰稳定范畴内,D_e 值灵敏度法概念清晰、简单而有效。
Based on the eigenvalue analysis techniques,this paper introduces a new appro- ach——D.sensitivity method to identify the best location of power system stabilizers (PSS) in the multimachine systems.Being combined with the method to select the parameters of stabilizers in the reference,the coordination problem of multima- chine stabilizers can be solved successfully.In addition,the limitation of the eigen- vectors method is demonstrated by comparison in the paper.Simulation studies show that D.sensitivity method has a clear conception.It is also easy and effective to be applied in the range of small disturbance stability problems.
