Research Of Daily Line Losses Statistics And Analysis Based On Line Losses Management System

Management and calculation of line loss analysis in power system to reduce line loss and improve the economic efficiency of enterprises is of great significance, and through analysis on the line loss can also improve the level of enterprise management, save the cost of human resource, it has become main topics of research in home and abroad at present.Firstly this thesis introduces the line loss management and calculation of related concepts and modern popular research methods, establishes the related concept foundation for the research and the elaboration. And according to the actual situation in Jiamusi region, the design of the three kinds of line loss calculation method, the root mean square current allocation method, optimization and improvement of the method of equivalent resistance of power flow method. Through the comparison analysis, it is found that the root mean square current sharing method, the advantage is to calculate the actual power consumption of the distribution transformer based on the original root mean square method. The disadvantage is that the assumption of conditions, the same proportion of user load increase or decrease, do not consider the voltage on the line down the line. Optimization method of equivalent resistance, the advantage is calculated, to load curve as the basis, the introduction of load coefficient, at the same time, the higher precision meter reading as the original data. The disadvantage is that the load factor is difficult to calculate. The improved power flow method, the advantage is the use of real-time data calculation, high accuracy, the actual situation of the line as the basis for the conditions, no assumptions. The disadvantage is the need to be based on the network before the number of. In short, by comparing the three methods, considering the complete data of the existing distribution network, as well as the more accurate calculation results, the improved power flow method is chosen, and the function software is designed and implemented.Combined with the idea and research methods discussed above, we according to the actual situation of Jia Musi regional analysis on line loss statistics and statistical analysis of daily smoking, paving the way for the necessity of the implementation of line loss and reconstruction. Thus forming the technology route of implementation Jia Musi area of line loss. Finally, focuses on the analysis and the implementation method of Jia Musi power company loss statistics after the technical effect and management effect, through the relevant data to prove that the actual effect, since the line loss statistics and statistical analysis of line loss management system implementation, to achieve the desired design goals.In addition, hope that through the exploration and research of line loss management, statistical analysis, can provide some useful experience for the relevant work within the scope of the power supply enterprise marketing management of power supply enterprise, in order to promote lean management play a positive role.
