Research On Theoretical Calculation Of Middle And Low Voltage Urban Distribution Networks And Line Loss Management

Now, with the continuous development of social modernization of our country, the problem of power supply has been changed from the universality contradiction to the structural contradiction. Electricity consumers are no longer alone as the only measure of access to electricity supply companies that fulfill their social utility functions. As a "central" prefix background of the State Grid Corporation, in addition to strengthening the collective promotion of functions, maintaining a steady supply of business development also becomes more and more important. The real measure of power companies on selling their products unit profit level can be concluded as two important economic indicators, the first, the average selling price of one product, and second, line loss rate of delivery of the product.Therefore, this article will combine two important economic indicators of line loss rate, as a main direction of this research, taking the low voltage distribution network line loss management work in the city as the axis, around the low voltage distribution network in the theoretical line loss calculation, Tangshan Development Zone of low voltage distribution network line loss management present situation and the plan design, the application of low voltage distribution network line loss management three aspects discussed, First, this paper briefly describes the status quo of low-voltage distribution network line loss management, and according to the shortage of the design of the line loss incentive mechanism; Secondly, this paper introduces the theory of low voltage distribution network line loss calculation of various algorithms, and fully applying theory of line loss research, line equipment energy conservation and loss reduction, marketing resource management three aspects, to add region theoretical line loss calculation results compared with the statistical line loss analysis, at the same time, puts forward the main line loss management and measures in the future. Therefore, the normal order of the electricity market could be maintained and electric power and energy could be stored. Unit loss can be also reduced and we can summarize a more adapted to the current low-voltage with new ideas, new technologies and new methods of distribution line loss management.
