Phase Ⅱ: Frequency Domain Analysis of Low-Frequency Oscillations in Large Electric Power Systems Volume 5: Studies of a Large System

摘要

This report describes eigenvalue calculations for a large electric power system using the computer program AESOPS. This work was undertaken to provide program testing and acquire experience in program application to large systems.\nData is supplied by the Electric Power Research Institute. Study results include descriptions of six modes of oscillation which involve numerous generators. Considerable emphasis is given to study procedures, including methods of deriving equivalent system models of reduced dimensions. The effects of power system stabilizers on damping is calculated for each of the six modes studied in detail.
