Medium Voltage Distribution Network Planning Of County District

As an important part of the overall urban planning,urban distribution network planning should be consistent and synchronized with the overall development plan of the city,its goal is to improve the reliability of power supply and quality of power supply through the planning,and solve some of the problems in the existing distribution network,which can make a clearer power supply zoning and a stronger grid structure,so that the economic and social development of the city will meet the surrounding area and the county industrial park power load demand.The load of Guiyang County is growing rapidly as well as the economy and the urban construction process,the medium voltage distribution network should be planted according to the development of the city.Firstly,the paper analyzed the medium voltage distribution network areas based on the city's overall plan,and summed up the problems based on the current situation of Guiyang County.then based on the calendar year socio-economic data and power data of Guiyang County,analyzed the load characteristics comprehensively and systematically.Through the analysis of the scientific data,predicting the power demand of Guiyang County.Finally,under the guidance of the power load forecasting results,according to the substation supply area division and the timing of the construction of the substation to the grid based on analysis of the current situation,demand-driven,in accordance with the relevant principles of planning techniques MV distribution network planning.Recent major plan is to solve the existing current situation problems and the status of the high load factor line,according to the new high-voltage substation distribution,regional re-division of power,to improve circuit interconnection rate and "N-1" check pass rate,focusing on the target space truss transition and meet the growing demand to load the recent new construction and renovation lines and target space truss conditions are ripe area;the medium-term plan,it is the further rationalization of substation power substation construction according to the timing range,to further address the status of medium voltage distribution network grid problem,implementation or transition to the target space truss;vision to build an ideal target space truss for the rapid and healthy economic development of Guiyang County to provide a solid foundation and strong protection.
