CET745 Power Quality I

Course Provider

School of Electrical and Electronic Engineering (EEE)



Academic Unit



The aim of the course is to introduce the new concepts of power system harmonics and focus on the effects of harmonic distortions on power system equipment. The course also focuses on harmonic problems in power systems and their solutions.

This course is part of:

- Graduate Certificate in Power Engineering
- FlexiMasters in Power Engineering

At the end of the course, learners  are able to:

1. equip the necessary skills to handle power system harmonics related problems; 

2. identify the cause or source of the problem and assess the severity of each problem with respect to the vulnerability of the affected devices and;

3. use computer modelling and simulations to examine the system responses and evaluate the effectiveness of various solutions.


Fourier series; waveform symmetry

Harmonic Sources

Single-phase rectification Three-phase current-source and voltage-source conversions

Effects of Harmonic Distortion

System response to harmonics; resonances; triplens Effects on power system equipment, rotating machines, transformers and capacitors Harmonic interferences

Coping with Harmonic Distortions

Solutions for triplens Passive and active filters



For engineers who wish to upgrade their technical knowledge and skills in the area of power and energy engineering, which can be applied in the power supply industry.
