The lean monitoring of the 10 kV high voltage distribution line loss is the essential requirement of line loss "four levels"management

and it is also basic premise of loss reduction and implementing loss reduction measures. Firstly

the key technology and fundamental condition of implementation of the lean monitor of the line loss of 10 kV distribution gird in Hunan province are described in detail in this paper. Secondly

the extraction

mining

distinguishing

calculation method and analysis process of power data are all researched deeply. Finally

a set of monitoring program structure for lean management of the line loss of 10 kV distribution gird is proposed

and the development of line loss monitoring module is completed based on big data platform. The application results of line loss monitoring module achieve the expected goal

and the feasibility of the related technology is verified.
