Abstract

This investigation aims to examine and demonstrate the problems associated with unbalanced voltages and voltage harmonics during the operation of a three-phase induction motor. The application of an induction motor under balanced voltages is used as a comparison tool to explore in more detail the effects of the motors process under unbalanced voltages and voltage harmonics.

In implementing this project, MATLAB was used as the simulation software. Through MATLAB, three separate programs were created that calculate and plot the torque-speed characteristics, line currents and the input and output power, which allowed for direct comparisons of each condition. However, to obtain such results, analysis of the motor operations must be considered for balanced and unbalanced voltages, and voltage harmonics, that involves parameter testing.

This project was completed to a satisfactory level, however due to the parameter testing resulting in incorrect values, this affected the direct comparison of the final simulation programs of the motor under each case.

This investigation provides a basis of further work that may be used to help reduce unbalanced voltages and voltage harmonics. It also allows for greater expansion into the realm of unbalanced voltage harmonics, which are ever present in real life three-phase induction motors.
