Mengzi City's "13th Five-Year Plan" Medium And Low Voltage Distribution Network Planning

Urban distribution network is one of the important infrastructure of city modernization construction,is also the key link of provide users with high-quality electricity.Its construction quality directly affect the development of urban economy,improve the quality of people's living standard,the optimization of investment environment,etc.Distribution network planning is an important task of power supply enterprise,in order to obtain the biggest economic benefits,power distribution network planning is to ensure the safety and reliability of power grid,and to ensure the economic operation of power grid,so the main task of the distribution network planning is,under the condition of feasible technology,in order to meet the needs of the development of the load to formulate feasible scheme of power distribution network development.The paper first through to the condition of low voltage power grid space truss structure,load in the supply capacity and the technical level of the equipment in the current condition of low voltage distribution network were analyzed,and for the subsequent distribution network load forecasting and demand to provide basic basis.Load forecasting result decides the scale of power grid construction,accurate load forecasting,will provide reasonable planning and good urban distribution,provide strong guarantee to save investment,in this paper,the third ZhangCai with big users and natural growth method,elasticity coefficient method,the classification of the power supply area calibration method to forecast the load of mengzi city development,and has carried on the careful analysis.Final combination has certain status quo analysis,load forecasting,planning objectives,technical principle,the paper puts forward the Mongolian year of medium voltage distribution network,the network frame and points in the transition plan,qualitative and quantitative analysis.In this paper,the city of mengzi\"much starker choices-and graver consequences-in\" in low voltage power distribution network planning are studied,in order to improve the quality of power distribution network planning,maximum meet the needs of load growth,is of great significance.
