【摘要】 电力行业是国民经济发展的支柱,为现代经济社会和谐有序发展提供了重要保障作用,电力基建项目建设是我国电力行业扩大规模再生产的外在表现,为现代经济社会的发展、资源配置以及市场供需平衡方面提供了非常重要的作用。输变电工程项目建设是我国电网企业为社会提供电力保障工作中的重要一环,输变电工程的好坏直接关系着电网企业电力供应的质量,它可以通过转换电压为工业用户和居民用户提供各自所需的电能。在确保项目质量的前提下对项目成本进行合理管控成为电力基本建设项目的重点工作。所以,对输变电工程项目进行综合评价可以从整体角度对项目进行评估,保证项目的正常运营。本文以本溪黑沟66千伏输变电工程项目为研究对象,从经济、技术、社会层面对该项目进行了具体分析,为我国电网优化配置企业有限资源、提高企业经济利益提供客观、科学的基本依据。本文首先对国内外关于输变电工程项目综合评价的研究现状进行整体简述,在充分了解输变电工程领域的前沿问题后,根据评价指标体系的建立原则,并与本溪黑沟66千伏输变电工程项目的具体情况相结合,构建适合于该项目的以经济评价指标、技术评价指标和社会评价指标为一级指标的综合评价指标体系;再者,本文采用熵权法进行指标赋权,从一定程度上避免了主观因素对最终评价结果的影响,使得最终计算结果更接近真实情况。使得结果更加客观可靠;然后用模糊综合评价方法,首先从经济评价指标、技术评价指标、社会评价指标对本溪黑沟输变电工程项目进行具体分析,后分别确定各个三级指标的隶属度,并通过三级指标单因素隶属度以及其权重确定二级指标的单因素隶属度,后根据二级指标的单因素隶属度以及其权重确定一级评价指标的隶属度,从而得到最终的评价结果。通过项目综合评价分析可知,本溪黑沟66千伏输变电工程项目在经济方面、技术方面以及社会方面都已经达到了电力基建项目建设的要求,并且通过本文分析我们可以证明,采用熵权法和模糊综合评价方法对输变电工程项目进行综合评价,可以保证最终综合评价结果的客观性、可靠性,能够对电力基建项目进行系统而全面的评价,从而能够为投资决策者提供具有科学性的决策依据。本文所构建的综合评价指标体系以及评价模型不仅适用于输变电工程项目,而且为其他领域工程项目评估提供了思路和方法。更多还原

【Abstract】 The electric power industry is the basic industry in China to support the development of the national economy.It is the important guarantee for the coordinated and harmonious development of the economic society.As the concrete manifestation of the power capital construction,the electric power industry plays an important role in social development,resource allocation and the achievement of supply and demand balance.Power transmission and transformation project construction is an important part of the power grid enterprises in China to provide electricity for the community,it is directly related to the quality of power of electric supply enterprises,it can convert the voltage for industrial users and residential users to provide their own required power.It is particularly important that the way that how to reasonably control costs,improve economic efficiency under ensuring the quality of the project.Moreover,carrying out a comprehensive evaluation to the power transmission project from the overall perspective of the project assessment can ensure the normal operation of the project.This paper considers Benxi Heigou 66 kv power transmission project as the research object,and specifically analyzes the project from economical,technological and social aspects to provide scientific and reasonable basis for the power grid enterprises to optimize the allocation of resources and improve economic efficiency.Firstly,the domestic and foreign research status of power transmission and transformation project comprehensive evaluation is reviewed,and the frontier problems in power transmission and transformation engineering are fully understood;Secondly,according to the establishment principle of the evaluation index system,this paper constructs the comprehensive evaluation index system which is suitable for the project with the economic evaluation index,the technical evaluation index and the social evaluation index as the first-level index,based on the concrete situation of Benxi Heigou 66 kV power transmission project;In addition,the entropy weight method is used to weight the constructed comprehensive evaluation index system,which avoids the influence of subjective factors on the final evaluation results and makes the final results more objective and reliable;Then,the fuzzy comprehensive evaluation method is used to analyze the project of Benxi Heigou power transmission and transformation project from the economic evaluation index,the technical evaluation index and the social evaluation index.Then the single factor membership degree of three-level indicators is determined,and the three-level indicators membership degree and its weight are determined to calculate the membership degree of the secondary index,and then the membership degree of the primary evaluation index is determined according to the single factor membership degree and the weight of the secondary indexes,so as to get the final evaluation result.Through the project comprehensive evaluation and analysis,we can see that Benxi Heigou 66 kv power transmission project have reached the requirements of power infrastructure construction project in economic,technical and social aspects,and we also can prove that the entropy weight method and fuzzy comprehensive evaluation method can ensure the objectivity and reliability of the final comprehensive evaluation results for comprehensive evaluation of power transmission and transformation projects,and can make a systematic and comprehensive evaluation for electric power infrastructure project,so as to provide scientific decision-making for investment decision-makers.In this paper,the comprehensive evaluation index system and the evaluation model constructed not only can apply to the power transmission project,but also provide the train of thought and method for the engineering project evaluation in other fields.更多还原
