Abstract: Lean management is a key means of energy conservation and loss reduction in distribution networks. Realize comprehensive management of electricity consumption, dynamic analysis of line loss, and real-time control of loss reduction on the basis of an intelligent platform. Its economic benefits are significant. This article takes the case of a 10 kV distribution network line loss as an example to analyze the main reasons for its high line loss. Carry out comprehensive and intelligent lean management on it. Fundamentally improve the energy-saving and loss reduction effect of 10 kV distribution network.
