A Frequency Dependent Steady State Model of Induction Motor Load For Harmonic Flow Studies

Abstract

A FREQUENCY DEPENDENT STEADY STATE, MODEL OF' INDUCTION MOTOR LOAD FOR HARMONIC FLOW STUDIES A.M. Shard, SMIEEE Electrical Engineering Department The University of New Brunswick Box 4400, Fredericton N.B.. CANADA MODEL DEVELOPMENT The paper presents a steady state harmonic model derivation for the induction machine. The model is baxd on a novel complex circuit msformation of induction machine equations to refer the rotor and magnetizing branch circuit to the stator side. The proposed m d e l can bc udlizcd in harmonic penetration and flow studies to replace the approximate model utilizing the locked rotm parameters currently used in harmonic flow programs.
