Title:ExploringAlternativePowerSupplySourcesforHigh-VoltageStartupof1000MWUnits
Abstract:
Inlarge-scalepowerplants,thestartupprocessofhigh-capacityunitsoftenposeschallengesduetotherequirementofareliableandcontinuouspowersupply.Thispaperaimstodiscussandexplorealternativepowersupplysourcesforthehigh-voltagestartupof1000MWunits.Byanalyzingthebenefitsanddrawbacksofvariousbackuppowersources,includingbatteries,dieselgenerators,andgridconnection,thisstudyoffersinsightsintotheselectionandimplementationofsuitablebackuppowersystemstoensureasuccessfulandefficientstartupprocess.
