| Feasibility study is a decisive work before construction project confirming and a scientific theory demonstration to conduct a comprehensive technical and economic analysis for target engineering before investment decision.In engineering construction investment,feasibility study refers to the study,demonstration and comparative analysis of planned project to conditional environment,social factor,economic factor and technology,and the prediction of social and economic benefits after the project is completed.On such basis,it integrates the necessity,financial profitability,economic rationality,technological progress and adaptability of the demonstration project and the possibility and feasibility of construction conditions to provide scientific proof for investment decision.Before the operation of Zhaigu 220 KV Station,Feixiang Station,Guangfu Station and Feixiang traction station are mainly provided by Dazhai Station.Since the route is longer and line loss is high,the power supply reliability is poor.The construction of Zhaigu 220 KV Station can reduce the power supply pressure Dazhai Station and narrow the power supply radius of surrounding 110 KV routes.It can reduce the line loss effectively and improve the power supply reliability.This paper starts from the necessity of substation construction and designs the specific construction process of the substation comprehensively.Furthermore,it takes general analysis for the economic level of project construction through partial financial data,and re-utilizes the analytic hierarchy process(AHP)to evaluate the index building.Finally,it creates a fuzzy mathematics method to take engineering comprehensive evaluation via expert scoring.It has obtained excellent construction index.Hence,it means the substation project construction is feasible,and the technical design is excellent. |
