Based On The Power Network Topology Of The Graph Database Research And Applications

In this dissertation, a research has been made on power network topology analysis method of graphic database. According to the status of network switch and other equipment, as well as their linking relations generate the bus and the network model, which are used in analysis of the power network applications. These applications include "Graphic order issuing", "Flow calculation", "Fault current calculation", etc. These can help monitor staff get the real-time running status of power network rapidly, accurately and comprehensively, and help to forecast the running trends in the power network, and deal with various problems inthe run-time power network.According to the deficiency of incomprehensive, inaccurate database, and complicated calculation method, resource consumption in monitor system of power network. Based on the domestic research and requirement analysis, the graphic database is redesigned, including parameters and linking relations of all the equipments in the power network. It provides complete and reliable database for the other software. The mathematical modeling method of linking relations is based on database and not on graphics. The facilitative, comprehensive mathematical description method is established with breadth-first approach for all the network equipments. This paper improves the breadth-first search of the network topology method, simplifies the calculation, and saves lots of time.This system has been used in anti-maloperation system in Hefei city, Anhui province. The running results have proved that the system reached expectant request in use.
