Although　the　current　technology　loss　reduction　platform　has　achieved　certain　results　in　theoretical　line　loss　calculation,　reactive　power　and　power　flow　scheduling　optimization,　it　lacks　effective　perception　of　the　reactive　power　compensation　capability　of　the　power　supplier.　It　also　lacks　accurate　guidance　on　the　reactive　power　compensation　willingness　of　the　power　consumer.　In　view　of　these　problems,　this　paper　puts　forward　a　construction　scheme　of　provincial　technical　loss　reduction　interactive　management　and　control　platform　considering　the　potential　of　reactive　power　compensation　of　both　power　supply　and　demand　sides.　It　also　puts　forward　the　design　and　implementation　scheme　of　two　technical　loss　reduction　advanced　functions　of　＂operational　state　diagnosis　of　low　voltage　reactive　power　compensation　equipment＂　and　＂special　transformer　user　reactive　power　potential　mining＂.　The　former　can　effectively　improve　the　effective　utilization　rate　of　low-voltage　reactive　power　compensation　equipment　and　fully　tap　the　network　loss　management　potential　of　a　low-voltage　distribution　network.　The　latter　forms　a　collaborative　governance,　and　a　mutually　beneficial　and　win-win　reactive　power　loss　reduction　system　through　the　information　sharing　and　interaction　mechanism　of　the　platform.　At　present,　the　platform　proposed　in　this　paper　has　been　put　into　practical　application　in　a　provincial　power　grid.　The　verification　accuracy　of　the　former　function　mentioned　above　is　93.33%.　The　latter　has　sorted　out　a　total　of　707　target　users　and　gradually　carried　out　treatment　under　the　guidance　of　the　platform　mechanism.　©　2023　Power　System　Protection　and　Control　Press.　All　rights　reserved.
