【摘要】：输变电工程作为我国重点建设的基础设施,对于经济的发展及人们生活质量的提高起着至关重要的作用。输变电工程的后评价工作是在项目完工后,对项目实施、所获得的技术、经济效益及项目的可持续性能进行整体评价。目前,国家电网公司基建标准化建设已经取得了重大成就,建立起“三横五纵”管理体系,实现造价管理领域纵向贯通;建立了造价管理全过程的统一标准和管理制度,通过环节管理的加强实现了工程造价的“三控”——可控、在控、能控。然而,目前的管理体系仍然缺乏对工程造价全过程管理及管理效果的有效评价,不便于及时反馈造价管理的有关信息并及时改进造价管控工作。为此,开展输变电工程后评价研究工作,创新性研究工程后评价体系,充分发挥管控的考核与反馈作用,客观、科学的评价造价管理工作水平,及时总结经验,不断和优化完善造价管控机制。为今后建设同类项目提供借鉴,以提高项目投资决策水平,完善投资决策机制。本文对河南信阳东500kV输变电工程进行后评价,主要从技术性能、经济效益、目标完成度几方面进行评价研究。首先,本文归纳总结了输变电工程后评价的相关基础理论,为后续评价工作的展开奠定了良好的理论基础。其次,根据信阳东500kV输变电工程的具体情况,确定输变电工程技术性能后评价的具体内容,建立评价指标体系,并采用特征值与物元可拓相结合的方法进行技术性能后评价。再次,依据项目投资状况等财务参数信息,本文对财务效益的评价参数进行了测算,对项目的盈利能力与偿债能力进行了分析,并针对电价、电量、容载比进行敏感性分析。最后,本文采用逻辑框架图的方法对输变电工程项目的目标完成情况进行分析,并通过内外部因素对项目的影响分析,对项目目标可持续性状况进行评价。此外,本文还建立了目标综合定量评价指标体系,采用熵权模糊评价法进行评价,得出该工程目标完成情况很好的结论。
[Abstract]:As the key infrastructure in China, power transmission and transformation project plays an important role in the development of economy and the improvement of people's quality of life. After the completion of the project, the post-evaluation of transmission and transformation project is to evaluate the technology, economic benefit and sustainability of the project. At present, the State Grid Corporation has made great achievements in the construction of infrastructure standardization. It has established a "three horizontal and five vertical" management system to realize vertical penetration in the field of cost management, and has established a unified standard and management system for the whole process of cost management. Through the strengthening of link management, the project cost can be controlled, controlled and controlled. However, the current management system is still lack of effective evaluation of the whole process of construction cost management and management effect, which is not convenient to timely feedback the relevant information of cost management and improve the cost control and control work in time. Therefore, we should carry out post-evaluation and research work of transmission and transformation engineering, innovate the post-evaluation system of engineering, give full play to the function of assessment and feedback of management and control, objectively and scientifically evaluate the level of cost management, and sum up experience in a timely manner. Continue and optimize and improve the cost control mechanism. In order to improve the level of investment decision and improve the mechanism of investment decision, this paper provides reference for the construction of similar projects in the future. In this paper, the post-evaluation of 500kV transmission and transformation project in Xinyang, Henan Province is carried out, mainly from the aspects of technical performance, economic benefit and target completion degree. Firstly, this paper summarizes the basic theory of post-evaluation of transmission and transformation engineering, which lays a good theoretical foundation for the subsequent evaluation. Secondly, according to the concrete situation of 500kV transmission and transformation project in Xinyang East, the concrete content of post-evaluation of technical performance of transmission and transformation project is determined, the evaluation index system is established, and the method of combining eigenvalue with matter-element extension is used to carry out post-evaluation of technical performance. Thirdly, according to the financial parameter information such as the investment condition of the project, this paper calculates the evaluation parameters of the financial benefit, analyzes the profitability and solvency of the project, and analyzes the sensitivity of the electricity price, electricity quantity, capacity to load ratio. Finally, this paper uses the logical frame diagram method to analyze the target completion of the transmission and transformation project, and through the internal and external factors to the impact analysis of the project, the sustainability of the project objectives are evaluated. In addition, a comprehensive quantitative evaluation index system of objective is established, and the fuzzy evaluation method of entropy weight is used to evaluate it, and the conclusion that the project goal is completed is very good.
