Abstract

Analysis of the stability of power systems following a transient disturbance involves the study of a large set of nonlinear differential equations.
 A new approach to the quantitative study of the transient stability of complex electric power systems (CEPS) is presented, using approximate evaluation of stability method (AES). 
The analytical steps for this method are detailed in this study. Also a constraint, which depends on the relative speed of angle variations, in applying this method for predicting the stability of CEPS is explained. 
The present work aimed to study the effect of many factors on the transient stability of a power system. These factors are fault clearing time (tc), damping factor (Pd) and transmitted power (P). 
A suggested flow chart of this method and results of its application to a 3 - machine system are given
