Transient Analysis of Synchronous Machines

5.1    Introduction

Since the forces impressed on the windings of a synchronous machine due to excessive current are one of the limiting factors in its design, the study of synchronous machine faults is an essential topic in the study of synchronous machines. Analyses of this class of problems become intractable almost from the start unless certain assumptions are made. One of the most powerful techniques for the solution of such problems utilizes the Theorem of Constant Flux Linkages, sometimes referred to as Doherty’s Law [1]. Robert E. Doherty was a renowned electrical engineer with the General Electric Company who wrote many classic papers on this topic during the 1920s.
