【摘要】 本文研究多机系统中稳定器(PSS)最佳安装地点的选择方法。F.P.deMello在1980年首次提出用特征分析法来决定各具体振模的主要源点,从而决定PSS的合适安装地点。那时,他对每个电机用的是二阶模型。本文进一步用四阶模型来拟合以求得更准确的结果,经比较两者的结果证明,简化的二阶模型,对于确定大的电力系统中PSS的安装地点,还是相当准确的。更多还原

【Abstract】 This paper discusses a techniqueof selecting the optimum locations in a multimachinc system for the power system stabilizer (PSS) installation. Eigenvector analysis is employed to determine the dominant sources of a particular mechanical oscillation mode in a multimachine system. This method was first introduced in 1980 by F.P. deMello using a second order model for each machine. Further development is continued in this paper using a fourth order model for more accurate results. Comparison of both results indicates that the simplified second order machine model is fairly accurate for the selection of strategic locations in a large electric power system for the PSS installation.更多还原
