Topology Analysis and Design of Power Distribution Network Spatial Database Based on GUID Code

Along with the information technology of power distribution network continuously improving, more and more application software services in the power distribution network, which provide reliable guarantee to the rural power distribution network safe and stable running. In software system which serves in the rural power distribution network, some part of software movement strictly relies on the power distribution network topology. Based on the analysis of characteristics of rural power distribution network topology, object-oriented methods were used to analysis the topology of network components, and SQL Server 2000 DBMS was applied to implementation of the rural power distribution network spatial database. In order to avoid the influences of human errors to the topology, this article proposed that using GUID (Globally Unique Identifier) code to mark network components and maintain the topology. Result of example testing shows that the topology design proposal which was proposed by this article can correctly describe the network topology, and use in the general analysis of power distribution network system.
