Abstract：Thedistribution network involves alarge numberof equipment，lines and nodes.It is necessary toobtain complete and accurate topology data. However，due to equipment failure，communication interruption and otherreasons，the qualityof data isoften dificult to guarantee.Therefore，a method for constructing an intellgent analysis model of distribution network topology based on three-dimensional laser scanning technology isproposed.The three-dimensionallaser scanning technology isused tocollect thepoint clouddataof thepower gridand construct thethree-dimensionaldata field.According tothethre-dimensionaldata field，thesumofall injectedcurrents in theelectrical islandiscalculatedand theelectrical island is tracked.According tothearrayrelationshipof theobject of the combined power grid model，the topology search of the node-circuit breaker and knife switch of the sub-networkofthedistributionnetwork iscariedouttodeterminethechargedstateoftheelectrical island，andthe directed graph search path of the topology information is determinedaccording to the remote signal displacement information，soas tocorrctthelocal topologyofthedistribution network.The experimentalresultsshow thatthe topological connectivityrate obtained bythe designed model is basicalyconsistent with the actual value，and the topological analysis performance is better.
