Dynamic Modelling And Simulation Of Three Phase Induction Motor For Enhanced Performance
ABSTRACT
This project is centered on enhancing the
performance of three phase induction motor. The MATLAB/SIMULINK function
program that makes use of the Runge-Kutta fourth order numerical method to
solve a set of first order differential system of equations describing
electrical and mechanical models was developed. MATLAB m-files were developed
and used to solve the Runge-Kutta fourth order method for both transient and
steady state respectively. The transient motor differential equations are
expressed in rotor reference frame with flux linkage as state variables. The
motor used in this thesis is a 3-phase, 4.5 KW, 50Hz, 2-pole, 210V induction
motor. The dynamic behaviors of the motor under varying voltages (210 - 250V),
varying poles (2 - 6) and load torque (20 – 50) were studied. By digital
simulation of the resulting differential equations, typical transient responses
of the motor were represented. Results reveal that increase in voltage leads to
increase in motor speed and rotor resistance, increase in poles leads to
increase motor speed and reduce in rotor resistance. Also, as load torque
increase motor speed increase rotor resistance increases.
