Abstract

A numerical damping analysis program (DAMP), based upon the frequency scanning method, for application to multi-generator power systems has been developed. This program permits the determination of electrical and mechanical torsional damping at arbitrary frequencies with respect to the individual generator under consideration within such a multi-machine system. Therefore, this allows the quantitative frequency domain analysis of power swing and torsional oscillation with due consideration for the effects of mutual interference among the generators. In this paper, first, the basic algorithm, modeling method, and validity of the new program are indicated. Next, the effectiveness of the program is demonstrated through SSR and other types of analyses for multi-machine systems
