Research On Comprehensive Evaluation Of 110kV Substation Project In Tangshan Airport No.2

Electric power industry is an important energy industry.It is very important for the development of our country's economy to provide energy supply for people's basic production and life.As far as the substation is concerned,it belongs to an important functional unit,which plays a very important role in the normal operation of the power system.The construction of substation has four characteristics.Its construction environment is very complicated.Its construction period is as long as two and three years.It requires high technical.Its investment is very large.It should be fully evaluated before the substation construction.At the same time,after the construction is completed and put into operation,it is necessary to evaluate the effect of the project.In this paper,the 110 kV substation project in Tangshan Airport No.2 as the research object,the study of the evaluation index system and evaluation method,the comprehensive evaluatio n.This paper describes background and significance and sums up the domestic and foreign research status of substation construction project evaluation.The basic theory of this paper is combed.110 kV substation project in Tangshan Airport No.2 is introduced.Based on expounding the principles of constructing the evaluation index system,from three aspects of economy,technology and society to construct the evaluation index system of 110 kV substation project in Tangshan Airport No.2,and expounds the content of the evaluation index system.O n this basis,a comprehensive evaluation model of 110 kV substation project in Tangshan Airport No.2 is constructed.Finally,this paper uses the established indicators and models in four steps to evaluate 110 kV substation project in Tangshan Airport No.2.First of all,the comprehensive evaluation index of 110 kV substation project in Tangshan Airport No.2 is evaluated.The second step uses variable weight theory to determine the weight of each index.The third step is to calculate the progress and determine the evaluation level.The fourth step which is also the last step is analysis of results.The evaluation results show that the 110 kV substation project in Tangshan Airport No.2 is the country's public project.The evaluating indicator which founded in the article is of great representativeness.The important indexes and factors can be included in the evaluation index system.The overall merit model set which is structured is in a position to fell together qualitative and quantitative targets,in order to accurately reflect the actual situation of the project itself and gets a more scientific evaluation results.
