Study On The Site Selection Of500kV Substation In Guyang, Houshan, Baotou, Inner Mongolia

Electric power industry is the basic industry of the national economy, the powersupply also being the basis for the development of the national economy. Substationconstruction as an important part of power system planning, plays an important role ofthe economy, the efficiency and the stability of the power grid construction, and alsothe security of grid operation. Substation construction environment being complex,long construction period, high technical requirements, large investment, decides theimportance and necessity of the evaluation of the substation site.This paper first introduces the theoretical knowledge of substation location,introducing the basic principles, selection of substation location and site preparationprocedure. Then analyzed the influence factors of various aspects of the substationsite, from the four aspects of the construction of environmental factors, the gridstructure factors, economic factors, social factors, constructs the evaluation indexsystem of substation location. Then introduce the comprehensive evaluation methodof evaluation of substation location. This paper chooses the improved fuzzycomprehensive evaluation method. Adding structure entropy weight in determiningthe weight of theory, reduce the influence of the accidental factors. Improving theevaluation model, make all the factors of influence on the evaluation results beingconsidered, which is beneficial to improve the objectivity and validity of evaluationresults. Adding levels thought in the process of evaluation, make the evaluationprocess of clear structure, convenient.
