| In recent years,the development of China’s economy is moving forward steadily,the quality of life of residents is increasing,with the increasing demand of electricity.At present,many provinces and cities of the electricity load is also growing,parts of the power supply has been unable to meet the needs of residents and businesses,which the construction of the power transmission project and fortune to be,because it has a significantly improved grid structure in a timely manner to meet the social demand for electricity and promote local economic development,an important role.Countries in vigorously beginning in the construction of large substation,power transmission project is the main content of the power grid construction also ushered in the opportunity of rapid development.The construction of power transmission project requires a lot of manpower and material resources,cost is very high;such a huge project in the management of requirements is relatively strict,power transmission project planning and design,implementation construction,use a different departments to complete;that the formation of such a mode of operation to each department to self-contained,each department person in charge is responsible only for their own links,no people on the project’s overall investment and interest is responsible for.This is serious defects existing in the management process,not a whole process of overall evaluation of the project.Therefore,under the condition of the environment,and vigorously carry out analysis and evaluation of the power transmission project comprehensive benefits is particularly important,which also to improve power transmission project in China as well as the similar project management level has a important practical significance.Based on the background of Shen Nan 500 kv power transmission project,evaluate the comprehensive benefits of power transmission project.This paper firstly expounds the background and significance,through literature review,to understand the research status at home and abroad,the comprehensive benefit evaluation of power transmission project and then introduces the theory and method of evaluation of the evaluation of the comprehensive benefits of the power transmission project,combined with the characteristics of Shen Nan power transmission project and benefit evaluation,selection the analytic hierarchy process and fuzzy comprehensive evaluation method forcomprehensive benefit evaluation of the project;then introduces Shen Nan power transmission project construction scale and analyzes the construction of the content,and from the technological and economic benefits,social benefits and energy saving analysis of the project in four aspects,and then to construct the evaluation index system of the project;finally,using the AHP calculation of each index The weight of indexes.According to the selection of the fuzzy comprehensive evaluation method on a comprehensive evaluation of the power transmission project benefits;obtained evaluation results as well,based on the results of analysis,reflect the Shen South power transmission project feasibility,and has good economic benefits,at the same time,in line with the requirements of saving energy and reducing consumption.The research results of this paper provide a scientific basis for the decision-making of power engineering projects and the promotion of electric power projects,but also have some reference value for the comprehensive benefit evaluation of the corresponding power engineering projects. |
