Development of a dynamic model of a mechanically driven polyphase AC generator

Abstract

This paper presents a computer model developed for the purpose of solving the differential equations of a three-phase, rotating field, salient pole, synchronous AC generator driven by a variable mechanical power source. The goal of this model is to provide a convenient means to accurately predict the mechanical and electrical dynamics of any engine-generator combination of the aforementioned design-type under various resistive and inductive electrical loading conditions. Intended practical uses of the model are for mechanical failure prediction, transient studies, and analysis for determining the suitability of the electrical power quality output of the generator for intended electrical loads.
