Research On Power Grid Planning Of Beidaihe New District In Qinhuangdao

Power grid planning is an important part of regional economic development and social progress,also an important measure to ensure long-term stable development of the power grid.Urban Power grid planning is the overall plan for the development of transmission,distribution and supply network within the city limits,whose purpose is to improve the existing supply capacity and meet the power supply capacity requirements of urban development based on the load of the city through the transformation of the existing power grid structure.Currently,there are still many problems in the Beidaihe New District power grid,restricting the development of Beidaihe New District.In order to meet the future needs of socio-economic development,research on power grid planning in Beidaihe New District has a very important practical significance.First,the overall development situation and the development problems in Beidaihe New District is studied,current development situation in Beidaihe New District power grid is analyzed,and the existing problems in power grid is summed up.Secondly,the mathematical methods used in load forecasting theory is studied.Beidaihe New District's long term power load is forecasted using load density method,GDP per unit value power consumption method,power consumption of industrial output method and per capita electricity consumption method.Finally,power grid in Beidaihe New District is planned,including voltage level selection,substation capacity estimates,the substation site selection and route path planning.
