Statistical Line Loss Calculation Of Distribution Network Considering Switching Power Consumption And Research On Loss Reduction By The Four Steps Analysis Method

Power line loss refers to the loss of electric energy in the transmission and distribution of power network.Power supply corporations usually regard the line loss rate as one of the important indicators to evaluate the economic benefits of companies.Compared with the data of the world’s major countries in recent years,China’s line loss rate is much bigger than the developed countries in the world.In recent years,the loss in the distribution network has become the main object of current loss reduction for power grid in the allocation process.So how to quickly and effectively reduce the loss of the distribution network,has become an important issue in front of China’s power supply corporations.In this paper,the statistical line loss calculation of power distribution network and the loss reduction measures of power supply company are taken as the research object,and the following aspects are studied:(1)Analysis of the mechanism of distribution network loss causes,the calculation method of theoretical line loss of the existing distribution network conducted a systematic summary,calculation method and found that the current statistical line loss,neglects actual operation change affect the value of the loss,the loss results calculated,the line loss management obstacle will the next to the power supply enterprise manufacturing.(2)Through the research of electric power enterprise loss module in current use of electricity information collection system,distribution management system,put forward a set of calculation method and cut change electricity distribution network statistics loss,coordinate the statistical line loss calculation using the two system,more accurately reflect the real situation of distribution line loss.(3)Various measures to reduce the line loss of distribution network are studied,and a set of loss reduction measures based on the four steps analysis method is put forward,which is based on the statistical line loss calculation method of distribution network,which is taken into account.The method is applied to the line loss management practice of power supply company,and good benefits are obtained.
