| Power grid planning is the main guidance and basis to power grid construction,is the basic work to further implement State Grid "One Strong and Three Excenences" modern power grid construction requirements.This paper mainly studies the network planning and connection modes in HeBei South Country,put forward the accord with the actual situation of south hebei rural power grid design optimization method and the typical cases,and this method and the analysis of typical cases,the planning and design of the corresponding solution.This article mainly from four aspects to study the rural power grid planning and design in southern HeBei:1.The power load forecasting is the basis and important part of power system planning and design,chapter 2 rural areas in southern HeBei power grid load forecasting,firstly analyzes the present situation of southern HeBei power grid electricity demand,put forward the thought and method of load forecast,and different voltage grade of load forecasting result is given.2.The power grid planning and design is always around the research of grid structure,grid structure and connection mode argument is the main part of the power grid planning and design.Chapter 3,the connection mode of rural areas in southern HeBei power grid and the grid structure analysis,first introduced the grid connection mode and is commonly used in the main electrical wiring,and then analyzes the present situation in southern HeBei power grid structure,then studies the grid space truss structure of different voltage grade transition mode,analysis of typical cases,and finally determine the different voltage levels in southern HeBei rural power grid,the optimal connection mode and network frame structure.3.Rural power grid intelligent modification to improve the stability and safety of the rural power grid operation is of great importance.Chapter 5 in rural areas in southern He Bei power grid intelligent planning and design are studied and discussed,mainly analyzes the planning scheme of distribution network automation and distributed power supply. |
