Study On The Planning Of Medium And Low Voltage Distribution Network In Sg City,GD Province

Since the beginning of the 21 st century,social production and life have undergone earth-shaking changes,social development has become faster and faster,people have become richer and richer,and their living standards have improved.Every household has bought a lot of high-tech electrical equipment.Not to mention the advanced equipment introduced by big factories and large enterprises,only more.Nowadays,electricity needs to be used.The use of electricity has developed into every corner of society.From production and life to astronomy and geography,all have to deal with electricity.The demand for electricity in the whole society is growing.At the same time,the society is always the same day,institutional reform,industrial restructuring is happening at any time,especially the changes in various systems,various.In 2015,the electricity reform No.9 document gradually formed the power market of China Southern Power Grid.Under the supervision of the members of the National Development and Reform Commission and the Reform Commission,the electricity price mechanism has become more and more perfect,which puts new demands on power supply.Based on the full understanding and research on the current situation of supply and demand in Sg City,this paper carefully analyzes the grids in Wujiang District and Qianjiang District in combination with the characteristics of Sg City in GD Province.Research,found the problem and the weak place of the grid,there are a lot of hidden dangers above the level4 risk in the grid.According to the overall development plan,industrial structure and layout,living standards and energy policies of Sg City,GD Province,select appropriate forecasting models,carry out scientific load forecasting,and take Wujiang District and Qianjiang District of Sg City as examples to plan in Sg City.After analyzing the historical data of Sg City,using the prediction methods such as the elastic coefficient method and the gray prediction model,the electricity and load forecasting is performed for the sub-sectors and sub-divisions,and a basic electric load forecasting scheme is made according to the historical data of the load,and then Carry out distribution network planning.
