VFD Based Performance Analysis of the Pump

Abstract

Electric power tconservation tis important tin tthe induction motor tfield tbecause ttwo-thirds of tthe tearths electricity tis being tconsumed tby tinduction motors. tAC motors tare said tto tconsume tmore tenergy tin the tindustry. The tmain problem twith tthese tinduction motors tare tthey consume very thigh tpower tconsumption. The tuse tof tvariable frequency tdrives (VFD’s) thas treduced this tcurrent. Variable Frequency tDrive tis ta common technique tused to vary tthe speed tof tAC timpulse motor by changing their input frequency. These tdrives tuse large motors tto start tsmoothly and constantly tadjust tthe speed. With tthe use tof tVFD’s, energy cost tsavings tare particularly important tin tpump applications where tthe load torque and tpower tvary twith respect tto tthe induction motor speed. tWith tthat tsystem tit helps tto treduce the operating cost tof tthe twhole tsystem, which tprovides operational benefits tand timproves tthe system. tLife. tThis paper contains texperimental tstudies tof induction tmotors with VFD tand tVFD tfor tpumps. tWith tthat study's analysis, this paper treflects ta treview ton tthe stimulus and performance analysis tof tthe tinduction tmotor twith tand without tVFD.
