Conventional AC electric power systems are designed to operate with sinusoidal voltages and currents, However, nonlinear and electronically switched loads will distort steady state AC voltage and current waveforms. Periodically distorted waveforms can be studied by examining the harmonic components of the waveforms. Power system harmonic analysis investigates the generation and propagation of these components throughout the system. A short cause and effect survey on sources of harmonics and their effects on distribution systems is conducted. As a basis for a power flow program different system components are modeled and the current spectrum of more common (harmonic producing) loads are not only simulated but also investigated through measurements. In these studies after a brief review of the theoretical basis for harmonics power flow analysis, a software is developed applying Object-Oriented Analysis and Design Techniques and it has been utilized in the case studies. Two cases are studied here from two different perspectives: (1) Case Study No. 1 (End User Perspective): The Kautex-Textron case in harmonic analysis was conducted to identify the problematic harmonic orders in order to design appropriate power factor correction means in a harmonically rich industrial environment. (2) Case Study No. 2 (Power Utilities Perspective): The Temporary Windsor Casino and the Casino Windsor case in which harmonics measurements were conducted to identify if there are any excessive harmonic injections into the local power utilities (Windsor Utilities Commission) network.Dept. of Electrical and Computer Engineering.
