| With the rapid development of national economy and improvement of people’s living standards, the contradiction between the supply and the social structure of electricity demand, the distribution network is not reasonable and power supply reliability is more and more outstanding. How to realize the distribution network construction and national economy development in harmony, it is urgent to solve the problem of distribution network planning.The Qinhuangdao Harbour District of western region "The 12 th Five Year Plan" initial, electricity demand growth is steady, the main reason is the area positioning for the regional sports culture and residential planning, Qinhuangdao City, no large commercial and industrial projects, regional construction land development slow. However, since 2013, the government planning to Bai TA Ling Zhai plate plate and provided new residential area projects under construction, the next few years the region will be formed the dream Bay residential and tourism area, residential area and other electrical Bai TA Ling region, the regional electricity consumption will increase sharply, so do the distribution network planning in the region can not only as the convoy escort in the area of social and economic development, and lay a solid foundation for sustainable development of more for the regional power grid.This article unifies the Qinhuangdao city harbor district of western regional economic and social development and the status quo of regional power grid, the regional power grid of the targeted research, analysis of the existing problems in the regional power grid, and puts forward the method to solve the problem of the regional power grid.This paper will use the load density method, average per capita of Harbour District of western regional load forecasting of electricity consumption forecasting method, through the comparative results of the two methods, that 2020 the area load capacity. Aiming at the problems existing in higher distribution capacity Harbor District of western regional power grid, a serious shortage of grid structure unreasonable, grid automation does not propose a solution to the problem: in the Harbor District of western regional planning.According to the State Grid Corporation of power engineering cost reference, and considering the actual situation of Qinhuangdao area, carried on the project investment estimate, by the end of 2020, the harbor construction area of western regional power grid is expected to invest 785 million yuan, the basic realization of power grid construction and the coordinated development of national economy goal. |
