Study On Theoretical Loss Calculation Analysis And Loss Reduction Measures Of Power Distribution Networks

With the construction of environment-friendly, resource-saving society’s needs, energy conservation has become the main direction of development of China’s power industry. Analysis of the distribution network for line loss, it is advantageous to develop a reasonable scientific theory loss reduction measures, and technical management. Distribution Network Line Loss Calculation for the power system reactive power optimization, equipment optimization, load the deployment and improve grid stability and economic efficiency has a key role.This article summarizes the domestic and foreign research and development direction of computing losses in power distribution lines,On the base of introducing the theoretical calculation of line loss, line loss reduction management and technical measures, the thesis proceeds from the practical situation, with the combination of loss calculation, analysis and research in actual grid. The author’s calculates are full of concrete examples with all system parameters and the real operation data, and the practical application of analytical methods proved to effectively play the role of the line loss reduction measures. Debasing the cost of electric energy supply which can enhances the management standard and increases profits of electric energy suppliers will obviously demonstrate theoretical and practical significance.This theoretical line loss calculation methods are analyzed and studied in this thesis, combined with the theoretical calculation of the actual grid. According to results, people can analyze line loss structure, improve calculation methods, detect specific measures, and propose concrete ways to reduce line losses. The correctness and feasibility of the subject which is argued in this thesis can be confirmed with the practical application.
