Research On Scheme Design And Evaluation Of Substation For Civil Building Project A

In an engineering project,the supply of all electricity load is assumed by the substation,and how to select the type of substation and determine the location will directly affect the whole project.On the whole point of view,the design of the substation affects the overall situation.For a long time,in the field of civil construction design,professional design personnel for substation design scheme selection mostly uses the empirical method to determine,to finalize the design of substation scheme also can simply from the angle of theory and specifications to carry out a descriptive explanation.However,such a process is many non professional personnel to be fully understood,it will exist to determine the final substation design have objections.This paper intends to the substation design scheme selection to study as a multi-objective decision problem,and using decision analysis theory,the substation design scheme abstract mathematical model,through a combination of qualitative and quantitative analysis method,the design scheme decision-ma_king process carefully structured mathematical expression,the final decision results are expressed in the form of mathematical,so for all scheme comparison results at a glance can as a final design scheme for substation based on a strong.In the course of the study,this paper to a large residential projects,for example by expert consultation method determine the application in the project alternative substation design,by consulting related experts to construct the civil building transformer design scheme evaluation index system,contains a total target layer,criterion layer and index layer three levels,and ultimately determine the reliability,security,economic and social impact of the four elements as the criterion of the evaluation index system of the layer.At the same time,the expert scoring method respectively to two alternative substation design score,value of the index of single factor evaluation is obtained.Based on introducing fuzzy analytic hierarchy process(FAHP)of two alternative substation design calculation and analysis and evaluation,and ultimately to comprehensive optimization design scheme for substation.This study combines decision analysis theory and project evaluation theory,combines the theory and engineering practice,to solve the practical problems.Through the study of this paper can be for the same type of civil construction projects substation design to provide certain reference,this paper introduces in detail the throughout the course of the study,in the subsequent design work,designers can learn from the research method of this paper on the design scheme for the optimization,also can be used on other issues in the field of design,introduces mathematical method can on traditional experience method,can greatly improve the efficiency of design workers,finally got in line with specific project practical optimal design scheme.
