Impact of Power Quality on Operational Characteristics of Induction Motor

Abstract

Phase isquirrel icage iinduction imotors iare ibroadly iutilized iin ielectrical idrives, iboth inon-movable iand imovable. iTheir ienormous iscope iutilizing iand iactivity iin inumerous imodern iapplications iare igiven iby itheir istraightforward idevelopment, idependability, ilow isupport iand igenerally ilow icost. iAdjustable ispeed idrives iwith iinduction imotor iand ifrequency iconverters iare iutilized iin ipractically iall ispecialized iapplications iwhere ithe ispeed icontrol ior imagnificent iunique iexecution iis irequired. iNonetheless, ienergy isaving iof iVFDs iare irelated iwith igreater iexpense, idrive iunpredictability, inegative ieffects ion isome iengine iboundaries iand iissues iidentified iwith ithe iforce iquality iand ithe ielectromagnetic isimilarity. iThen iagain, ithe iconsistently iexpanding inumber iand iintensity iof idirtying iloads i(non-linear iloads, itime-variant iloads, iand iso ion) iassociated iwith iappropriation iand imechanical iorganizations icause ia inoteworthy ibending iin ithe iline icurrent. iTheir igeneral ipower iis inot, iat ithis ipoint iimmaterial iregarding ithe inetwork ipower. iThis icauses ia ideterioration iof ithe ivoltage iquality ithat imay iimpact ithe iother iassociated iloads iincluding ielectrical idrives. iConsequently, ithe iforce iquality iin ithe imains iis isignificant ifor ilegitimate icapacity. iWe ifocused ion ithe iquality irecords, ifor iexample, ithe itotal iharmonics ivoltage idistortion, ifrequency ivariation, ithe ivoltage iunbalance i2factor iand ithe ivoltage idip ito itheir ieffect ion iactivity iattributes iof iinduction imotor idrive, isince ivoltage iharmonic, inon-balanced ivoltage isegments iand ivoltage ifluctuation ihave iadversely iimpact ion irotating imachine i[4], i[5]. iIn iparticular, iharmonic iand inegative/zero isequence icomponents icause iextra ilosses, ithe iparasitic ivibration iand ispeed ipulsation iof ithe iIM. iThis ipaper iendeavor ito icontemplate ithe iissue irelated ithe ipower inature iof iinduction imotor ilike i- ivoltage idroop, iunbalanced ivoltage iand ifrequencies ivariation.
