Study On Evaluation Of Substation Site Location

Electric energy is a very convenient and very environmentally friendly,clean and clean energy for the environment,so it plays a very important role in today's society and people's daily life.With the strengthening of global environmental awareness and technological progress,electricity has gradually replaced the trend of other energy,its application has also been greatly developed.With the increasing demand for electricity,the importance of grid planning is becoming increasingly important.The choice of substation location has its great significance and far-reaching impact,the choice of substation location can promote the reliable operation of the entire grid,and in the daily operation and maintenance will ensure its safety and economy,can be described as its status is very important.On the issue of substation site selection,many scholars have invested in it,and advanced the research progress of substation site selection,and achieved remarkable results.In order to make the location of the substation more reasonable,we must continue to improve the substation location method.Reasonable and reasonable substation location will provide a good guarantee for the construction and operation of power grid.The main idea of this paper is to apply the gray theory to the selection of the substation position,and use the gray relational analysis method to optimize the alternative site of the substation.This paper first introduces the basic task of the substation site selection,that is,the main work content,and then elaborates on the significance of the research on the substation site selection.In the basic principle of substation site selection,the factors affecting the site selection are screened and analyzed.From the technical requirements,basic conditions,environmental conditions,social environment and network architecture,the specific meaning of each index and The content has been optimized to build the substation site selection index system.In addition,the gray theory is applied to the selection of substation position.The gray relational analysis method has no strict requirements on the number and distribution of samples.It is also suitable for small sample number and non-distributed samples,so it is very suitable for substation location problem The Finally,a concrete example is given,and the alternative site of the substation is analyzed by gray relational analysis method from each index,and finally the theoretical best site is obtained.
