Power Special Planning Of Ningbo East Newtown A3 Block Based On Spatial Load Forecasting

The planning area is the Eastern Newtown A3 plots of Ningbo City Jiang Dong District which covers an area of about 58 acres with more than 620000 square meters of building area that the building area on the ground is more than 480000 square meters. The paper makes a plan for the supplement of electric power of the eastern part of Ningbo Newtown A3 block based on the method of spatial power load forecasting. Firstly, the paper introduces the spatial load forecasting that includes the advantages, the improvements and the procedures of the method. Then it analyses the general conditions of A3 plot, and on the basis of the full investigation and study of Ningbo Newtown A3 plots’planning and design, the future power distribution characteristics, the future load characteristics, population growth, social and economic development, it forecasts the maximum load with the method of spatial load forecasting. Next, basing on the forecasting results, the paper calculates the total distribution capacity combined with economic operation load radio. And it provides different supplement plans that consider several facts depending on different voltage level and then discusses the feasibility of these plans. After that, the paper designs the medium-voltage distribution network belong to recommended power supplements taking the power supply capacity, reliability, the development of the surrounding network and so on into consideration, and at last decides the supplement plans of A3 plots. Finally, it summarizes this article and puts forward some suggestions and prospects to the future work.
