Generation of Power Quality Disturbances using MATLAB Simulink

Abstract

Proper operation of a power system depends upon the quality of power supplied to consumers. To have preventive measures and to design power quality monitoring equipment, it is necessary to have proper information about the signals. To design relevant equipment and compensation devices, the signals are to be generated. The objective of this paper is to generate power quality disturbances in MATLAB Simulink environment. The disturbances considered for analysis are voltage sag, swell, interruption, harmonics and transient. The aim of this paper is to present different signals which can be used for signal processing and to extract more information from the signals about the disturbance. The generated disturbance signals can be used to observe the effect of preventive action by analyzing the extent of disturbance reduction. The Simulink models can be used for modeling of corrective devices.
