Planning And Design Of 10kv Target Network Grid In Dongzhi County Of Chizhou City

The planning of distribution network is the basic link in the planning activities of power supply enterprises.The planning quality of distribution network directly affects the operation level and investment benefit of distribution network,which has the effect on reducing network loss,improving reliability and ensuring power quality.Operation management of the distribution network.It is of great significance to improve the rural network planning and construction plan to achieve the urban and rural power equalization process,meet the comprehensive realization of the well-off society to rural power security,comprehensively improve the grid resource allocation capacity,safety and stability level and economic operation effici ency,and ensure the reliable power supply of the rural network.The research content of this paper is mainly divided into the following three parts: Accordin g to the overall development planning layout of Dongzhi County,the distribution network of the ar ea is analyzed,and the overall situation of Dongzhi County,power supply area overview and load distribution are analyzed in detail.On the basis of the electricity consumption situation and the status quo of the distribution network,the problems of the distribution network are summarized.Through the analysis and analysis of scientific data,the demand for electricity in Dongzhi County in the next few years is predicted.On the basis of the above,the planning goal of Dongzhi County distribution network is put forward.It is planned that the power supply capacity of Dongzhi Power Grid will be sufficient until 2022,which can meet the needs of load growth caused by rapid urban and rural economic development and increasing urbanization rate.The phenomenon of insufficient power supply capacity of the network and the "low voltage" problem,the elimination of high energy consumption and distribution,and the focus on the distribution network of 35 k V and above,and the distribution network of 10 k V and below are detailed in the near future,transition period and long term.planning.According to the scale and engineering quantity of Dongzhi County power grid planning,the investment estimation and planning effect analysis were carried out.The power supply indicators were significantly improved,and some low voltage and distribution line aging problems were solved.Through detailed planning,the direction of power grid development is determined,and the problems existing in the current distribution network are sol ved.The medium and long-term construction and transformation of the distribution network in Dongzhi County are guided to ensure that the east to the power grid meets the standards for municipal construction andtransformation,and transmits power to the l arge power grid.The system will coordinate development together to ensure that electricity is delivered and will fall.To meet the needs of the long-term annual power load and power consumption growth,to ensure the national econom y development,social development and residents’ safe and high-quality electricity.
