Quzhou County Distribution Network Planning Study

Distribution network planning is the basic link of planning activities in the power supply enterprises,the quality of planning of distribution network directly affects the distribution network level and investment benefit,to improve the reliability and security of power quality is no less than the influence of the operation and management of distribution network to reduce network loss.We should improve the rural network planning and construction plan to achieve the equalization process of urban and rural electricity,meet the needs of fully realizing the well-off society to ensure rural power,improve the power grid resource allocation capacity,safety and stability level and economic operation efficiency,and ensure the reliable power supply of rural power network.The research content of this paper is mainly divided into the following three parts:According to the overall development plan of quzhou county in the area of power distribution network analysis of the status quo,in quzhou county area are analyzed in detail the overall situation,the power supply area,load distribution and utilization situation,the present situation of distribution network is summarized on the basis of the problems existing in the distribution network.Through the analysis and collation of scientific data,the power demand of quzhou county in the next few years is predicted.On the basis of above,issuing quzhou county distribution network planning objectives,planning to 2020 weeks abundant ability of power supply,can satisfy the rapid development of urban and rural economy,improve the urbanization rate of load growth needs,basically eliminated the phenomenon of distribution network power supply capacity is insufficient and the problem of "low voltage",eliminate production with change,and the key for more than 35 kv power distribution network points in the near future,10 kv and below,the transition period,the forward has carried on the detailed planning.According to the size of the quzhou county power network planning,and analyzed the effect of investment estimation and planning,the power supply indexes significantly increased,at the same time solve some of the low voltage,power distribution line aging,technical problems such as high loss.Through detailed planning to determine the direction of the power grid development,strive to resolve the current problems of distribution network,further perfecting the network frame structure,to better practice of the "economic development,electric power first" development philosophy,to better meet the song weeks development and social improvement of living standards,to better guide the quzhou county power grid construction projects in 2013-2020,really built "reasonable structure,high technology applied,power supply quality,low power loss," the strong power grid region.
