Research On Synchronous Line Loss Analysis And Index System Management Of Power Supply Enterprises

With the rapid growth of social economy,continue to promote the reform of electric power,China’s electric power industry presents the fast development momentum,leapfrog development,change the mode of development,improve the level of equipment,energy saving and loss reduction significantly.But because of the uneven distribution of resources,the imbalance of economic development,there are still some contradiction between power supply and demand,so saving energy and reducing measures is recognized as part of energy supply contradiction loss is an important way to improve the quality and efficiency of economic growth,is the basic policy of our country.Line loss rate is a comprehensive economic and technical index for power supply enterprises.For the statistical time period,the sale of electricity meter reading errors,abnormal electricity stealing electricity customers are the main factors causing management loss,especially due to time constraints for the sale of electricity meter in different period statistics seriously restrict the accuracy of line loss rate,so it has real loss statistics of line loss management is not necessarily loss the power network.Thus,the statistical calculation of line loss rate for sale and sale at the same time has become the best line loss rate data to avoid the influence of different periods.In order to accurately grasp the situation of power network loss,the line loss management based on the calculation results of line loss rate at the same period is an important way to understand the real line loss rate.With the full acquisition of power meter,full coverage and high level of topological data,the major Power Grid Corp have already fully carried out the management of line loss for sale.This paper begins with a review of current research status and development trend of line loss management and line loss management at home and abroad.On the basis of discussing the factors of line loss,the advantages of line loss management are compared by comparing the methods of line loss management.Subsequently,according to the current state of the operation of the power grid software of the State Grid Corporation,a feasible system integration requirement scheme is designed for the realization of the Synchronous line loss management.On this basis,the calculation model of line loss at the same period is designed,and the principle,train of thought and practical method of line loss analysis are explored from two aspects of traditional line loss analysis and line loss service analysis.Finally,according to the status of Power Grid Corp,Daxing power company as the research object,according to the characteristics of different periods,designed the index over the same period,three sets of line loss evaluation evaluation index evaluation index over the same period in order to adapt to the loss of promotion needs in different periods during the same period,improve the index of line loss management mechanism,to provide an effective means for power grid enterprises tocarry out the management of synchronous line loss.
