Situation Analysis And Planning Study For The Power Distribution Grid Of Dingxing Power Supply Co., Ltd

With the rapid development of national economy, the rural power distribution gridgradually exposed the problems of the grid construction laged behind the load growth,power shortage, low reliability, poor quality and so on. The aim of this paper is toaccelerate the implementation of the development strategy of the new countryside, newelectric power and new services, provide sufficient power supply and high quality servicesfor county economy development and new rural construction, satisfy the laod demand,improve the power supply capacity, optimize the gird structure, reduce loss and providescientific guidance for Dingxing gird construction.This paper analyzes the present situation of the DingXing rural power distribution grid,finds the problems of the unreasonable grid structure, low control level and so on, plansthe layout and grid structure of the substation whose voltage class is35kV and under,determines the quantities and investment scale of the35kV and10kV grid projects in theplanning period, guides scientifically the gird construction and reconstruction projects inthe next stage. Meanwhile, this paper combines the national economic developmentplanning of DingXing, as well as the electricity consumption in recent years, through theinvestigation and study, forecasts and prospects the future electricity consumption level,and then put forward the planning of the grid structure to ensure the safety and economyof the grid operation.
