Statistics And Analysis For Line Loss Of Power Network Based On Data Warehouse

In this paper, the actuality and trend of domestic and overseas line losses calculation is analyzed, and the principles and methods are studied. According to the characteristic of 10kV(6kV) distribution network, a new method is putted forward. The method uses BP model trained by PSO to map the complex relationship between the energy losses and the feature parameters which have influenced the line loss. And the program of line losses calculation is respectively designed for different voltage level power networks.For conveniently statisticing and analyzing the result of line losses calculation, the paper adopts the last SQL Server 2000 to build the data warehouse, and presents the on-line analysis tool based on Excel, and exploits the query tool and report forms system based on data warehouse.
