Research On Rural Power Grid Differentiation Planning In Hengshui Region

In China,there are many common features in rural power grids,such as large number of users,decentralized distribution,small load density,complex power grid structure,many branches,low natural power factor and low voltage quality.Rural power grid is an important part of the power system is an important infrastructure for rural construction.In recent years,the demand for electricity in rural areas is exuberant,the electricity consumption of rural residents is growing rapidly,and the problems of insufficient power supply capacity,low reliability and equipment aging of village medium and low voltage power networks are prominent.The scientific planning of rural power grids is not only an important part of the overall planning of the power system,but also the fundamental guarantee for rural electrification and agricultural modernization.The gap between rich and poor in Hengshui is relatively large,and the development of rural power grids in various counties is not balanced.Hengshui City Zhongjing County belongs to the regional core of Hengshui development,and the basic management is good,the data are complete.In order to study the status of rural power grid and future load development,this paper forecasts the typical rural power supply load in Jingxian area,And on this basis for grid planning.The planning to supply and reduce damage as a constraint,in-depth analysis and diagnosis of rural Jingxian power supply for the status quo and problems and combined with rural areas load forecast results to improve the power supply capacity and power quality as the goal,combined with Hengshui area According to the actual conditions in each county,the planning objectives of medium and low voltage distribution network in rural power network in Hengshui area,the typical scheme of network and equipment material selection principle are put forward,and the corresponding investment estimates are made for all counties in Hengshui.
