Study On Distribution Network Planning Of YQ Town In Zhejiang Province

With the continuous development of economy,the acceleration of urbanization,and the improvement of people's living standards,the dependence on electricity is increasing.So how to solve the increasingly prominent contradiction between supply and demand,optimizing the existing distribution network grid structure and enhancing the power quality and power supply reliability are currently hot issues in the power industry.The main contents of the thesis are as follows:First of all,Combining the economic development status of planning area of YQ town in Lin'an with that of the near-term and long-term planing for the first time.To obtain a more systematic results of the division and providing a reference basis of the district for the future planning,the analysis of distribution network is carried out from various aspects.Also,the current status distribution network is analysed and the existing grid problems are revealed.Secondly,according to the current situation of YQ town,regional development planning and the nature of land,the forecast of the spatial load is carried out from the point to the larger scale in YQ town.To provide the load basis for planning,the load situation during the planning period is expounded.Finally,,To provide reference of the project arrangements within planing period,the planning of high,medium and low voltage distribution network in YQ town is studied,the demand of near and long-term load and the development of power grid in the planning area is proposed,and the target grid of YQ town is defined based on the principle of technology of the distribution network.So,the duplication of construction and waste of resources can be reduced.
