Research On The Comprehensive Evaluation Of 220kV Substation Construction Project Of GaoBeiDianNan

The development of electricity plays an important role in the improvement of China’s economic development,national security,social stability and the quality of life of the people.Modern civilized society has nothing to do without power supply.The construction of 220 KV power transmission project can increase the regional power supply capacity and improve the quality of power supply in the region.With the improvement of regional power supply capacity and power supply quality,the normal production of local enterprises will have power supply protection,which can provide the basic conditions for expanding the scale of production,so as to play a positive role in regional economic development.The establishment of a power transmission project needs to take into account the technical,economic and social benefits and so on,these factors affect each other,which is difficult to accurately distinguish and define.The comprehensive evaluation of the project refers to a kind of technical and economic activities which systematically analyze and objectively summarize the purpose,the implementation process,the benefit,the effect and the influence of the project.The comprehensive evaluation of project can determine whether the expected target of the project is achieved and whether the main benefit index is realized.At the same time,it can find the reasons for the success of the project,summarize the lessons learned,timely and effectively feedback the information,improve the management level of the new project in the future and achieve the purpose of improving the investment benefit.In this context,a method of combining AHP and fuzzy comprehensive evaluation is proposed.Based on the general theory and method of comprehensive evaluation of project,this paper constructs a comprehensive evaluation model of power transmission and transformation project.Based on the actual investigation and analysis,this paper constructs the evaluation index system,including technical indicators,economic benefit index and social factors,and uses the analytic hierarchy process to determine the weight.Then through the fuzzy comprehensive evaluation method for quantitative analysis of various factors,in view of which can carry out comprehensive evaluation of power transmission project.A empirical example shows that the model can achieve good evaluation results..
