Abstract

In ithis ipaper, ivarious ivoltage iinjection itechniques ifor idynamic ivoltage irestorers i(DVRs) iare ianalyzed iwith iparticular ifocus ion ia inew imethod iused ito idecrease ithe irating iof ithe ivoltage isource iconverter i(VSC) iused iin iDVR. iA inew icontrol itechnique iis iproposed ito icontrol ithe icapacitor-supported iDVR. iThe icontrol iof ia iDVR iis idemonstrated iwith ia ireduced-rating iVoltage iSource iConverter. iThe ireference iload ivoltage iis ipredicted iusing ithe iunit ivectors. iThe isynchronous ireference iframe itheory iis iused ifor ithe iconversion iof ivoltages ifrom irotating ivectors ito ithe istationary iframe. iThe icompensation iof ithe ivoltage iswell, isag iand iharmonics iis idemonstrated iusing ia ireduced-rating iDVR. iThus ithe ivoltage iprofile ialso iincreased ilosses iare ialso idecreased. iA inew icontrol itechnique iis iproposed ito icontrol ithe icapacitor-supported iDVR. iThe icontrol iof ia iDVR iis idemonstrated iwith ia ireduced-rating iVSC. iThe ireference
