A Study On Distribution Network Planning Of YiZhuang Xincheng

Yizhuang Xincheng is one of the three key constructions in Beijing,in the distribution network planning of Yizhuang Xincheng,first of all,the basic situation of its distribution network is studied,based on these,overall planning objectives of the construction of Yizhuang Xincheng power grids are proposed,the development ideas as well as the planning and development objectives are discussed;Then make the year 2007 to be the base year of planning,the year 2020 to be last year in which the electricity load grows no more(that means the load is saturated),according to the long-term planning scenarios of Yizhuang Xincheng,using the load density method to do the long-term Load forecasting,and in accordance with the regional maximum load utilization hours to get the total using of electricity a year;Next,based on the load distribution results,the programs of substation site and volume can be got through the network planning software and human intervention;Finally,assessments on the planning grid is made by using the city power network planning software on the planning grid to test the reliability and economy, combined with data analysis a scientific and rational planning programe is given.
