The Research Of Distribution Network Networking Basis On Mathematical Models With The Network Loss Integral Minimum For Target Function

With the electric distribution network of the city developing, the ability that electric network with each other power supply and the redundancy degree of electric network had a quite heavy exaltation,so it is possible that the electric distribution network gains economy efficiency and exalts the credibility by network reconfiguration. The electric distribution network reconfiguration becomes the popular research realm of recent years, the report of the CNKI academic trend manifestation: from 2003, academic pay attention to this problem straight line ascension, and obtain a great deal of result.The electric distribution network reconfiguration, also called electric distribution network compages, it changes net topology and realizes schedule to of target by switch operation of electric distribution system. Aiming at the characteristic of the electric distribution network, this text puts forward one set of model of the electric distribution network configuration characterization, and puts forward a new of load flow calculation method on this foundation. Base on the new load flow calculation, condition network not wreath net and component however carry for limit condition, with a time network expense minimum for objective function, put forward a set of project of the electric distribution network reconfiguration. This project calculate way is simple, the speed is very quick and overcomes problems, such as too many nodes of the electric distribution network, dimension balefulness and so on, and nonexistent astringency problem.
