Modeling and Simulation to Support the Teaching and studying in power quality

Abstract

Power quality is a major concern in electrical power system. The power quality disturbance such as sag, swell, harmonic distortion and other interruptions have impact on the electrical devices and machines and in severe cases can damage the whole system. This article presents some simulations of power quality disturbances due to short circuits, motor starting and capacitor switching using Matlab/Simulink software. These models contribute as basic simulations for power quality research and teaching as well as towards testing solutions to improve power quality.
