EFFECT OF DAMPER WINDINGS ON THE TRANSIENT STABILITY OF SYNCHRONOUS MACHINES

Abstract

The scope pf this dissertation Is to study the dynamic behaviour of a synchronous machine under transient conditions. In order to make a detailed study of the transient stability equations showing the variation of torque and load angle of a synchronous machine connected to •a fixed supply voltage under various types of ape1?iodic diaturbancea have been developed with the assumption of constant field I lu., lin agas. The behaviour of the synchronous machine Is i investigated by the step.by..st~p method using the equations developed. The effect of damper windings from stability considerations alone is analysed ;j detail. t'etaiis of experimental tests conducted to verify'. `the theoritical analysis are given at the end.
