Power Theft Prevention and Power Quality Improvement using Fuzzy Logic

Abstract

This paper deals with Fuzzy logic based power theft prevention and power quality improvement. It involves comparison between the total load supplied by the distribution transformer and the total load used by the consumer and the error signal is used to identify the power theft. Load (energy) and voltage are fed as input to the Fuzzy logic controller and the corresponding change in output voltage is provided by the controller to improve the power quality and to prevent the power theft. Simulations are done using MATLAB and the results of the simulations are provided. It helps us to analyze the efficiency of intelligent control in electrical systems.
