The Study On Post Assessment Index System And Model Construction In Transmission And Distribution Project

As the saying goes,“The development of electricity industry has a prior to others”.it shows that electricity industry is closely related to the development of society,since our electricity industry promises to provide secure,economic,clean and sustainable power supply to our country.As a public infrastructure industry,power supply is to ensure the development of all walks of life and the happiness of millions of households.Recently,electric power construction projects have been increased year by year,in other words,the number of approval items is increasing gradually.However,the power transmission and transformation project is lacking in operation management procedures as a whole such as the feasible study,project management,construction stages and completion acceptance.The post-completion of the project is the basis of project cycle management.The post evaluation of power transmission project,which will objectively analyze the aim,effect,differences in actual results and expectation aims,aims to provide the basis for the following decision-making and help decision-makers to improve the decision-making level and investment benefit.Therefore,it will summarize the shortcomings in the project constr uction process and put forward the corresponding comments and suggestions.The post evaluation of transmission and transformation projec t will not only meets the needs of power grid enterprises,but also improve the healthy development of the electric power.Through post evaluation of power transmission project,we can achieve the unity in the speed,structure,quality and efficiency of the power grid development to further enlarge the investment and improve the efficiency of investment in power grid enterprises.Based on the theory of post evaluation of power transmission project,this essay summarizes the impacts and the evaluation index system of power transmission project evaluation by means of fuzzy analytic hierarchy process and grey correlation method.It emphasizes the contents and aims of the post evaluation of power transmission project.According to the earlier information,it focuses on research significance,different approaches,construction thoughts,the aims and contents of the post evaluation,including the analysis and investigation of the domestic and foreign power transmission project.Through detailed analysis,it concentrates on the principle of the establishment,evaluation model and evaluation criteria.Then take the "Kowloon 110 thousand volt power transmission project" as an example,it does research on it,including the construction scale,the need,the construction period and the present situation.Then according to the principle of building index system and the index construction step,combined with the characteristics of complexity of power transmission and transformation project,it reaches the original evaluation index and solves the limitation,overlap index,poor representation and other issues at the same time in the initial guarantee.The post evaluation of power transmission project will obtain the final index by means of grey correlation method,which is used to select the index of post eva luation of power transmission project.For the 10 level indicators,30 level two indexes,it will judge matrix one by one and watch over the post evaluation in order to form the Kowloon 110 thousand volt power transmission project.According to the specific problemsencountered in the implementation of the project,this essay provides the control measures in the management of power transmission project to ensure that post evaluation of power transmission project.The content of this paper provides the reference for the further research of power transmission project post evaluation system,and will further improve the power supply enterprise management level and economic benefits as well as decision-making advice.
