Research On Fuxin Power Grid Planning Based On Combination Forecasting Method

The grid is a very important part in the development of each city,the development of the power grid is related to the economic construction of the city,and the planning of power grid as power grid construction and transformation of the basis in the city's economic development plays an important role.This paper puts forward the research plan of Fuxin power grid based on combination forecast method based on the understanding of the.Fuxin area and the basic situation of Fuxin power grid,the growth rate of proportional coefficient method based on elastic coefficient method and time series analysis method combined forecasting method of Fuxin power grid in 2018,2020 and future years of power load prediction of Fuxin power grid planning and target Principles have been formulated for the Fuxin grid in 2018,2020 and the prospective year of the 500 KV,220KV and 66 KV power grid planning programmes.The planning scheme in this paper through the short-circuit current calculation,electrical verification,power flow calculation and N-1 contingency analysis of the calculation results show that the Fuxin power grid in 2018,2020 and future years of 500 KV,220KV and 66 KV power grid planning is feasible.The scheme can for Fuxin power grid in 2018,provide a good the prospect of 2020 and in future development.
