Voltage　sag　can　cause　abnormal　interruption　of　production　process　of　industrial　users,　resulting　in　huge　economic　losses.　In　view　of　the　single　governance　angle　and　poor　governance　effect　of　existing　voltage　sag　mitigation　schemes,　according　to　the　electrical　characteristics　and　physical　attributes　of　industrial　processes,　this　paper　proposed　electrical　means　focusing　on　voltage　control　and　physical　means　focusing　on　process　quantity　maintenance.　From　the　point　of　view　of　process　parameters,　the　effects　of　various　mitigation　measures　were　measured　in　a　unified　way.　A　voltage　sag　mitigation　method　was　proposed,　which　combines　the　installation　of　customized　power　equipment　with　the　renovation　of　plant　facilities,　in　order　to　maintain　the　process　parameters　during　the　period　of　disturbance　and　avoid　the　serious　consequences　of　process　interruption.　Considering　the　investment　cost　and　income　of　various　mitigation　measures,　the　allocation　of　mitigation　measures　was　determined　with　the　goal　of　maximizing　the　net　present　value　(NPV)　of　the　scheme.　The　mitigation　strategy　proposed　in　this　paper　was　applied　to　a　new　energy　material　enterprise.　The　results　show　that　the　proposed　method　can　effectively　mitigate　the　consequences　of　voltage　sag　and　is　more　economical　than　the　traditional　voltage　compensation　scheme.　KEY　WORDS:　©　2021　Chin.　Soc.　for　Elec.　Eng.
