Simulation of Three-Phase Salient Pole Generator under Operating Conditions

Abstract

The three-phase synchronous generators are still the backbone of most electric power plants in the world. Many researchers still study synchronous generators in attempts to improve their performance and reduce losses in iron core, copper windings, friction ball bearings, and moments of inertia due to mass and rotor diameter. One of the important characteristics studied insynchronous generator behavior is the generator’svoltage regulation (VR%). Over the past century, researchers have developed four practical and mathematical methods to determine the value of the combined voltages of synchronous generators. This article describes a new method based on the impedance method, the magneto motive force (MMF) method, and the Potier method. The new method effectiveness evaluation is conducted via calculating the four methods and their application to a synchronous generator. The article also offers practical and theoretical recommendations to improve the results and increase flexibility in changing loads as their power factors change.
