Study On Post-evaluation Of Economic Benefit Of Deshannan 220kV Power Transmission And Transformation Project

With the development of social economy,people’s demand for electricity is also rising.Several years after being put into operation,each power project needs to evaluate economic benefits to sum up experience,optimize and improve.Economic benefit evaluation first to collect the economic data from the construction to operation stage,and then the selected economic benefit indicators using a series of or quantitative or qualitative evaluation method,finally will get the results of analysis comparison,summarizes the current shortcomings and feasible experience,for the future power engineering construction planning and service.This paper expounds the current domestic and foreign power construction projects,especially the power transmission and transformation project in detail,and selects "Deshannan 220 k V power transmission and transformation project" as the research object,and carries out a scientific and rigorous discussion and analysis of its economic benefits.From the project implementation process,financial benefit,project impact and sustainability of four aspects,select suitable analysis index,combining hierarchical analysis and fuzzy comprehensive evaluation method,established the fit 220 k V power transmission and transformation project scale economic benefit evaluation model,through research and analysis,listed the power transmission and transformation project and after the construction and operation of the advantages and disadvantages,summarize results and prospect.
