Analysis Of The Current Situation Of Power Grid And Planning Research For Xinglong

In recent yeas,with the rapid development of the social economic,the demand for electricity is dramatically increased.This situation brings a great challenge to the plan of State Grid Corporation.Faced with the constantly increasing power load,the power supply enterprise is confronted with a number of problems preventing its long-term development.Therefor,it is the first important task that the reasonable network planning,and also,it is a new research field in the academic circles.Not only based on Xinglong economic developmental status,The distribution of the power load in the region,the economic and social development tendency in the future,but also combined with the load prediction,the evaluation index for power system operation,this paper puts forward the distribution network planning in detail,and introduces the distribution network planning and rebuilding.Firstly,through analyses of the distribution network in XingLong,we found a number of problems in power grid.And this provides the basic theory the late planning.Secondly,a variety of load foresting algorithm are used to forecast the load increasing and confirm that the subarea load forecasting method is the forecast result.Finally,throughanalysis the status of the 110 kV,35kV and 10 kV grid,we find out the planning in detail.The results show that the plan can meet the electricity requirements,and increasing the quality of power supply,and improving the electricity situation.
