Development Of Theoretic Line Loss Calculation System Based On GIS And Method Of Lower Loss

Distribution line loss calculation is the energy loss reduction, improvement of line loss management is an important technology management tools. Can be found by calculating the loss in power distribution grid, find the weak links in network operation, control loss of the composition, calculation and analysis can be exposed through the management and technical problems, loss of reduction to provide theoretical and technical basis, targeted of reducing losses to take reasonable measures to seize the key to the work of reducing losses and improve the effectiveness of energy loss reduction, the line loss management more scientific. So line loss calculation in power grid construction and transformation process and economic efficiency power supply enterprises play a very important role.Firstly, the tradition of several more mature line loss calculation methods are analyzed, characterized by a comprehensive comparison of their proposed power flow method and the point segments selection method, respectively, as Luanxian Power Authority of 35kV, 10 (6) kV line loss calculation methods based on the knowledge learned, combined with the actual operation of electric power flow calculation method for the forward and backward substitution method is appropriate improvements to the point of the first end section of the law current distribution methods appropriate amendments;. Second, AT Microsoft Visual Studio.NET development platform, using B / S and C / S system combined structure, using Orcal database, application C # language has developed a GIS-based electric power Luan County line loss calculation system, and successfully applied to the Electricity Generating Authority of Luan County Line Loss Management. Finally, electric power distribution system for Luan County theoretical line loss calculations conducted a special research, analysis, and contrasted with the actual situation, the system energy from the transformer, power optimization of power grids, improve power, strengthen the demand side management and improve the measurement and other aspects of the accuracy of the system to reduce line loss of specific measures.
