Research On The Location Model And Its Application Of Transformer Substation

In recent years, China’s power grid construction is booming, and also made a very satisfactory results. The present study is a grid construction tends to improve the momentum to the development of power grid construction in all areas have a lot of research. Substation sites are preferred as an important part of network planning for the economic stability of the entire power grid construction, efficiency and grid operation,security plays a vital role, using a reasonable method substation site, you can in the construction and operation of the grid on the basis of the economic stability and improve the sustainability of the power grid construction.Firstly, through research and analysis of the characteristics of the substation site,combined with the actual substation construction, multi-perspective method to establish a set of evaluation system. Among them, infrastructure, natural environment, cultural environment, grid architecture, technical conditions, economic and energy saving aspects of building seven substation siting evaluation system. Secondly, on this basis, this paper uses the method of historical data and cut data Chebyshev inequality method for quantitative indicators were revised and determine its fair value range, the basis for the calculation of the following membership; the same time, This paper constructs evaluation model of AHP and Fuzzy Comprehensive evaluation Method: Analytic Hierarchy Process to determine the index weight; for quantitative indicators, based on the principles of before and after the establishment of a membership function to determine the single factor evaluation matrix; for qualitative indicators, combined expert judgment and fuzzy statistical method to determine a single factor evaluation matrix; the index weights and univariate fuzzy comprehensive evaluation matrix, come and evaluate the effectiveness of the overall evaluation of the effect of the four-level indicators. Again to Wangdu110 k V 110 k V substation, for example, to verify the rationality and scientific and feasible index system and evaluation model. Finally, the paper points out the development direction of the substation site and make its future development prospects.
