Abstract:Rural power grid is a weak link in the distribution network. In addition to the proposal of rural revitalization, it is urgent to increase investment in rural power grids and improve voltage qualification rate and power supply reliability. However, traditional subjective distribution methods cannot Meet the requirements of grid yield. Based on the investment model of rural power grid equipment, this paper proposes a new rural power grid investment allocation method based on BP neural network evaluation, and the reliability of further verification method, and the county level of Anshun City. As an example, the rural power grid discusses the feasibility of the proposed method and provides some reference significance for the rural power grid investment of power supply enterprises.
