Abstract


Distribution network is as a hub link between generation/transmission system and the users. The power system’s supply capacity and quality are embodied through the distribution system. to meet the users’increasing demands for power supplying, improving the reliability of distribution network is to be a urgent problem. To improve the reliability ,it is necessary to have a scientific analysis and research of distribution network’s characteristics and reliability.The distribution management information systems are various. but they are built of different power system models, leading to the difficult for data sharing and exchanging among management information systems. Common Information Model(CIM) is such a standard power system model that if all software systems use CIM as a standard to build power system models, they can achieve information exchanging and resource sharing easily. The content of Geographic Information System of distribution (GIS) becomes rich gradually. However, the secondary development based on GIS has not been mature, such as the analysis of reliability of distribution network, the reconfiguration of distribution network, the calculation of power flow and network loss and so on.This paper is proposed above the context. This article is based on GIS and as CIM a standard to establish a database to achieve GIS data by realizing the interface between GIS and distribution CIM database. Based on above, develop distribution network reliability analysis software, Specific content as follow:1) According to CIM, propose a certain rules of distribution network data mapping to the relational database and build a set of distribution network database of CIM ;2) Based on CIM, a modified depth-first search algorithm is put forward in order to complete the distribution network shortest path searching.meantime, this article develops a algorithm to evaluate the reliability of distribution network according to the topology analysis algorithm above ;3) Realize the interface between GIS and distribution CIM database;4) Develop a system of distribution network reliability evaluation using JAVA language.
