Industrial Power Factor Correction (P-0194) (MFN 2826)

Abstract

The main idea behind the project was to design and implement a real time power factor monitoring and correction system. Power factor calculation can be done by measuring the lead/lag angle between the voltage and the current waveform of any non linear load. Then by real time high speed switching of capacitor banks the compensation for lead /lag angle would be achieved in a closed loop. The basic goal of our project is to maximize the power factor to its optimum value as much as possible. Using different techniques we can acquire the desired result. The Power Factor Correction method is used for improving the efficiency of a system and reducing the electricity bill. In this regard a full market survey was conducted, which compelled us to undertake this daunting challenge of power factor optimization. Further study strengthened our determination in pursuing this as out final year project. Electric power consumers pay heavy fine each month imposed by electric supply companies because of low power factor. With the accomplishment of power factor correction schemes used in our project, it will cut down on these higher electricity costs and benefit the industry as a whole.
