Research On Loss Reduction Measures For JiZhou Distribution

The line loss is consumption and loss of the energy generated in the process of power transmission and marketing for the network operation enterprises.The line loss rate is an important measure of electric power enterprises comprehensive technical and economic indicators,which reflects and embodies a power network planning and design,production and operation and operational management level,which is an important economic and technical index.In this paper,starting from the actual operation situation of JiZhou grid,it introduces the basis,the method and the steps of theoretical line loss calculation,and analyzes the overview of the JiZhou distribution,load characteristics,the present situation of line loss management as well as the theoretical line loss calculation.On this basis,using the actual operation data of the typical day of JiZhou grid,it calculates the theoretical line loss of 35 kV,10 kV,0.4 kV power grid respectively,and compared with the statistical line loss.Finally,according to the characteristic of the distribution network,it puts forward the technical measures of reducing line loss,management measures and distribution network loss reduction measures.
