As the development of domestic economy and improvement of material living, the society needs more elecrticity year by year. Furthermore,it requires higher qualit and stability. How to plan the distribution network in community si an important and comstructon. A new theme is to plan a short-term and long-term goal to satisfy the city development including industry area, development area, residential area, and cultural area etc.This paper firstly introduces the common load forecasting method and their weakness and strength. A scientific losd forecasting method is a combination with several load forecasting methods. Besides this, the paper also introduces the requirement for high voltage distriburion network planning and medium voltage distribtution network planning. At last, a demonstration si stated and testified.This paper comprises six chapters. In chapterⅠ,the significance of the thesis,current research works of domestic and foreign, and thedistribution network planning are in troduced. In chapterⅡ, the load forecasting methodsandtheir strength and weakness are discussed. In chapterⅢ, high voltage distribution network requirement and planning method is stated. In chapterⅣ, the step of planning nedium voltage distribution network is introduced and strongly emphasis cite of transformer and network connection of 10kV systerm. In chapterⅤ, a demonstration is discussde and analysis the procedure and methods of distribution network planning. The mainworks of paper are summarized in the last chapter.The innovations of the paper are as follows.1. The paper take the angle of city community or huge community, to consider the distribution network planning, to satisfy he development requirement of city community and increasing huge residential zone.2. The paper discusses the several load forecasting methods,and points out it should use the suitable load forecasting method according to the specific situation.3.Clear up the instructor of sspc, put forward the new flow of load forecasting method to city community.4.Anlayse a great deal of dates in instance, lend good idea for next work.
