Power Grid Planning Of Jiujiang

With the rapid development of the economic,the increasing demand for electricity and the rising urban load appeared in Jiujiang day by day,thus the imbalance between the supply and demand of power supply has occurred.Jiujiang power grid planning is made to ease the contradiction between power supply and demand in Jiujiang,so that the power grid can adapt to the needs of urban economic development,and ensure the coordinated development of urban power grid and economic.This paper introduces the research background and gives an induction of the method of power grid planning.Based on the analysis of the current situation of the regional and power grid in Jiujiang,find the existing problems of the power system.According to the historical data of Jiujiang electric power and load,drew the electric quantity and load curve of each area.By using the natural increment rate method,the elastic coefficient method and the partition prediction method,the forecast results are obtained.According to the results of load forecasting,the 500 kV,220kV,110 kV power grid planning in Jiujiang is determined,and selects the substation site,estimates the investment.Finally,the main conclusions are obtained through the analysis of the planning results.
