Research to study Variable Frequency Drive and its Energy Savings

Tamal Aditya

Abstract: This paper presents the working principle of Variable Frequency Drive. The performance of VFD is also described. The simulation model is simulated using MATLAB Simulink and their results are also analyzed. The Total Harmonic Distortion (THD) in waveforms is also analyzed. The use of Variable Frequency Drive has been increased dramatically in the field of HVAC applications. The common applications of VFDs are in air handler, chiller, pumps and tower fans. A better understanding of Variable Frequency Drives with leads to improve in application and selection of both equipment and HVAC system. This paper is intended to provide a basic understanding of VFD terms, VFD operations and Power Factor improvement, Harmonics mitigation by VFD and a simulation project to show how VFD is beneficial for energy savings. In addition to this paper will discuss the comparison between Variable Frequency Drives and other technologies with respect to industrial standards
