Title:DesignProposalforAutomationRetrofitofa110kVConventionalSubstation
Abstract:
Withtheadventofmoderntechnologiesandtheincreasingdemandforefficientandreliablepowerdistribution,theautomationretrofitof110kVconventionalsubstationshasbecomeanessentialaspectofthepowersector.Thispaperpresentsacomprehensivedesignproposalfortheautomationretrofitofa110kVconventionalsubstation,addressingthechallengesandbenefitsassociatedwiththisupgrade.Theproposeddesignconsiderskeyaspectssuchascontrolsystemarchitecture,communicationnetworks,protectionandmonitoringsystems,andintegrationwiththeexistinginfrastructure.Byimplementingthisdesign,thesubstationwillbeequippedwithadvancedautomationcapabilitiestoenhanceitsoperationalefficiency,reliability,andoverallperformance.
