The Development Plan Of The "13th Five-year" Power Grid In Yuanyang,Henan Province

In recent years,with the improvement of the economic level,the electrification and informatization has made great progress in the countryside.Meanwhile,people also need more and more electricity.Along with the rural electric load power supply ability insufficiency,the lower of capacity load ratio,the weakness of space truss structure,the poor reliability and the difficulties of power grid construction,obvious the seasonal load and the difference of peak valley,a reasonable and scientific power grid planning can not only improve the power supply ability of power system and ensure the normal life of people,but also can obtain good social development,accelerate the construction of urbanization and make people have reached a well-off level at an early date.In order to solve the problems existing in the present situation of power grid as soon as possible,improve YuanYang grid power supply capacity and quality of power supply and promote the coordinated development of the power grid and the municipal infrastructure,this paper studies 13 th Five-Year Yuanyang County power grid planning.Fistly,this paper summarize method of rural grid planning.By conducting a detailed investigation of social economy and current situation of power grid in Yuanyang,I have analyzed the existing problems in the power grid.Then,according to the analysis of load forecasting and electric power balance,the plan of power supply for substation and the voltage level of each district are planned.Finally,the reliability of the planning scheme is judged by the analysis of electrical calculation,and the rationality of the proposed scheme is judged by economic analysis.
