Researching On Comprehensive Evaluation Of Yantai 220kV Yexian Substation Reconstruction Project

The transformation of the substation can improve the system integration degree and improve the security and reliability of power supply.With the rapid development of China’s economy,some original substations have been unable to meet the requirements of power supply.Therefore,their will be more and more substation reconstruction projects.This paper firstly introduces the research background and significance of comprehensive evaluation of Yantai 220kV Yexian substation reconstruction project,as well as research status of substation project comprehensive evaluation theory,and the main research methods.Secondly, the article introduces some theories of Yantai 220kV Yexian substation reconstruction project,such as introduction of substation construction project,connotation of substation construction project comprehensive evaluation,general process of substation construction project comprehensive evaluation and comprehensive evaluation methods of substation construction project.Comprehensive evaluation methods of substation construction project include the expert evaluation method,comparative method,principal component analysis and causal analysis method and so on.On the basis,the paper constructs comprehensive evaluation of Yantai 220kV Yexian substation construction project.This article firstly introduces the general situation of the project.on the basis of considering the principles of project comprehensive evaluation index system,this paper analyzes index from project economy,technology, society and establishes comprehensive evaluation index system of Yantai 220kV Yexian substation reconstruction project.Nextly,this paper establishes comprehensive evaluation model of Yantai 220kV Yexian substation reconstruction project,including comparative analysis f the main methods of comprehensive evaluation of electric power project,the matter-element evaluation model,variable weight matter-element extension model construction based on ideal interval method.Finally,this paper evaluates Yantai 220kV Yexian substation reconstruction project.This paper evaluates index from project economy,technology, society distribution network intelligent transformation project in village.Finally,this paper applies variable weight matter-element extension model construction based on ideal interval method in comprehensive evaluation of Yantai 220kV Yexian substation reconstruction project.
