This paper present the impacts of power quality issues namely harmonic distortion, transient  in electrical system due to Variable Frequency Drives (VFD) known as Power Drive system (PDS) and its elimination techniques is investigated both side at the  Point of Common Coupling (PCC) and input side of motor. The Harmonic measurements of electrical supply system and motor drive are done, with the help of Matlab software to determine whether a significant amount of harmonic in currents or voltages is presented. From these measurements and analysis,  the  impact  of  harmonics  is  analyzed  and  found  that  the  harmonic  content  of  electrical power system & motor  drives  to  be minimized by suitable strategies like Multi pulse converter or Active front end converter, within  the  limits  of  international  harmonic  standards like IEEE 519 and IEC. In  recently,  multi  pulse and multilevel  drive  solution  gained  an increased  attention  due  to  their  effective  harmonic  elimination which is implemented in Matlab/Simulink. Sinusoidal Pulse width modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM) techniques are used to generate switching sequence for the multilevel inverter and a detailed harmonic study has been carried out.

Keywords— Variable Frequency Drives (VFD); Pulse Width Modulation (PWM); Sinusoidal pulse width modulation (SPWM); Space vector pulse width modulation (SVPWM); Induction Motor (IM); Point of common coupling (PCC); Power Drive System (PDS).
