摘要
Abstract
According to load features of low load density area, the use of 20kV as medium voltage distribution level of this area is put forward.Considering the farthest power supply distance, the method of determining the number of out-let is obtained, and a power grid model which fits the low load density area is constructed.On this basis, the mathe-matical model for economic analysis of the grid in low load density area that uses annual cost as the object function is put forward.Then the economic characteristics of different voltage levels are compared, and the feasibility of the 20kV voltage level in low load density area is verified.关键词
