The Reasonable Range of Life Cycle Utilization Rate of Distribution Network Equipment

Abstract

The utilization rate of power equipment plays a decisive role in the economic operation of power utilities. By determining the reasonable range of life cycle utilization rate of the distribution network equipment, it is of great significance to the management of the distribution network equipment. In this paper, the reasonable range of the life cycle utilization rate of distribution network equipment is determined. The life cycle utilization rate of distribution network equipment depends on the burden rate, load rate, and life expectancy rate, whose reasonable values are analyzed and exemplified, respectively. The optimal model of the burden rate in different conditions is established. The different load characteristic curves are also given by sorting out the load data. The calculation method of the life expectance rate is presented in this paper. The reasonable range of the life cycle utilization rate is finally obtained by defining the boundary condition of its composition. By setting the reasonable range of life cycle utilization rate of the distribution network equipment, power utilities can improve efficiency.
