【摘要】：输变电工程经济效益及可持续性后评价研究工作,具有重要的学术价值和实际意义。本文阐述了输变电工程经济效益及可持续性后评价的背景和意义,介绍了项目后评价国内外的研究动态,并进行经济效益及可持续性后评价理论研究。结合国家、电力行业项目后评价的相关规定以及输变电工程投资特点,基于充分的调研工作,深入分析临运500kV线路工程的经济效益及可持续性,并运用相关数学模型手段,对临运500kV线路工程进行了后评价实证研究。在临运500kV线路工程经济效益后评价研究中,本文首先结合工程实际情况和特点,构建能够反映临运500kV线路工程经济效益的后评价指标体系；然后采用熵权模糊评价模型,运用AHP法与熵权法结合确定指标权重,采用模糊评价法确定隶属度,对临运500kV线路工程进行实证研究；最后得到评价结论并提出针对性的建议措施。在临运500kV线路工程可持续性后评价研究中,本文首先结合工程实际情况和特点,构建能够反映临运500kV线路工程可持续性的后评价指标体系；然后确定评语集和评价标准,对评价指标进行数据处理；最后采用BP神经网络评价模型,通过运用Matlab软件对临运500kV线路工程进行基于BP神经网络的可持续性后评价实证研究,得到评价结论并提出针对性的建议措施。本文采用了定性和定量相结合的评价方法,系统全面地评价了临运500kV线路工程的经济效益及可持续性,对电网企业的输变电工程建设起到了一定的积极作用,具有一定的现实意义。
[Abstract]:The research on economic benefit and sustainability of transmission and transformation project is of great academic value and practical significance. This paper expounds the background and significance of economic benefit and sustainability post evaluation of transmission and transformation engineering, introduces the research trends of project post evaluation at home and abroad, and studies the theory of economic benefit and sustainability post evaluation. Combined with the relevant regulations of post-evaluation of national and electric power industry projects and the investment characteristics of transmission and transformation projects, based on the full investigation work, the economic benefits and sustainability of 500kV line engineering are analyzed in depth, and the relevant mathematical models are used. An empirical study on post-evaluation of 500kV line engineering is carried out. In the study of post-evaluation of economic benefits of 500kV line engineering, this paper firstly constructs a post-evaluation index system which can reflect the economic benefits of 500kV line engineering, and then adopts entropy weight fuzzy evaluation model. AHP method and entropy weight method are used to determine the index weight and fuzzy evaluation method is used to determine the membership degree. Finally, the evaluation conclusions are obtained and the corresponding suggestions are put forward. In the research of post-evaluation of sustainability of 500kV line engineering, this paper firstly constructs a post-evaluation index system which can reflect the sustainability of 500kV line project, and then determines the evaluation set and evaluation criteria, according to the actual situation and characteristics of the project, and then establishes a post-evaluation index system that can reflect the sustainability of the project, and then determines the evaluation set and evaluation criteria. Finally, using BP neural network evaluation model and using Matlab software to carry out the sustainable post-evaluation research based on BP neural network. Get the evaluation conclusion and put forward the targeted measures. In this paper, the qualitative and quantitative evaluation method is used to evaluate the economic benefit and sustainability of the 500kV line project systematically and comprehensively, which plays a positive role in the transmission and transformation project construction of the power grid enterprise. Has certain realistic significance.
