【摘要】：随着电力体制的改革和经济社会的发展,国家进一步加大了对电厂项目改进、扩建的投资力度,提升了我国电力产业的总体水平。燃煤火电建设项目一般具有投入资金巨大、耗时长等特点,如何确保项目在竣工投产后,企业可以收回必要报酬率以实现企业自身效益；如何在项目建设中提高设备性能和工艺水平；如何在获得利益的同时减少污染物的排放和保护地区环境,这些疑问都是国家和企业,甚至相关学者需要考虑的问题。本文所作的燃煤火电站扩建项目后评价研究,旨在用科学的方法找出影响燃煤火电站扩建项目的因素,并对这些因素进行分析研究,从而得出该扩建项目的优劣。为此,本文做了以下工作。首先,通过查找相关文献了解国内外该领域的研究情况,并搜集有关燃煤火电站扩建项目的相关理论,为本文的研究提供理论基础与材料支撑。其次,根据评价指标体系构建原则,构建了包括供热专项建设、热电联产效益、扩建区发展和污染物处理以及生产物资可持续供应四个一级指标的燃煤火电站扩建项目综合后评价的指标体系。第三,为了定量和定性两种方法结合,即充分考虑决策者结合整个项目实际情况的经验判断,避免盲目的追求数据信息,又能够更合理的给出各指标的权数,采用AHP以确定各指标的权重。第四,运用物元可拓理论确定了待评物元、经典域、节域,继而得到了项目关于各评价等级的关联度,得到最终的基于AHP的物元可拓评价模型。最后,将该评价模型运用到景德镇电厂燃煤火电扩建项目上,对该项目优劣进行判断。通过采用本文所提出的评价模型,确定了待评价项目的评价等级为“优”,进而得出评价结论和项目中的主要问题,并结合这些问题提出了相关建议,以便将本文的研究成果落地实施。本研究运用科学的分析方法对燃煤火电项目的建立项目时的决策问题,投入建设前的准备工作,对于施工过程的设计,以及生产之后的运营管理等过程进行全面分析,基于燃煤火电扩建项目评价要素分析构建了评价指标体系及物元可拓评价模型,并通过实例分析对项目的供热专项建设、热电联产效益、扩建区发展和污染物处理以及生产物资可持续供应进行综合性的研究评价,发现项目中的缺陷和优势,总结经验教训,为后续类似项目的决策提供依据,提高项目管理水平。
[Abstract]:With the reform of electric power system and the development of economy and society, the state has further increased the investment in the improvement and expansion of power plant projects, which has raised the overall level of the electric power industry in China. How to ensure that after the project is completed and put into production, the enterprise can recover the necessary rate of return to realize the enterprise's own benefit, how to improve the equipment performance and technology level in the construction of the project, and so on, how to ensure that the project is completed and put into operation. How to reduce the emission of pollutants and protect the environment at the same time is a problem that the country, enterprises and even related scholars need to consider. The post-evaluation study of coal-fired power plant expansion project is carried out in this paper. The purpose of this paper is to find out the factors that affect the expansion project of coal-fired power station by scientific method, and to analyze and study these factors so as to obtain the advantages and disadvantages of the expansion project. For this reason, the following work has been done in this paper. By looking up relevant documents to find out the research situation in this field at home and abroad, and collecting the relevant theories about the expansion project of coal-fired power station, it provides the theoretical basis and material support for the research of this paper. Secondly, according to the principle of constructing evaluation index system, A comprehensive post-evaluation index system of coal-fired power station expansion project including four first-grade indexes, including heating special construction, cogeneration benefit, expansion area development and pollutant treatment, and sustainable supply of production materials, was constructed. Third, In order to combine quantitative and qualitative methods, that is, to take full account of the decision makers' experience judgment of the actual situation of the whole project, to avoid blindly pursuing data information, and to be able to give the weights of each index more reasonably. Using AHP to determine the weight of each index. Fourth, using matter-element extension theory to determine the subject element to be evaluated, classical domain, domain, and then get the project about each evaluation level of the correlation, Finally, the final matter-element extension evaluation model based on AHP is obtained. Finally, the evaluation model is applied to the coal-fired thermal power expansion project of Jingdezhen Power Plant to judge the merits and demerits of the project. The evaluation grade of the project to be evaluated is determined as "excellent", and then the evaluation conclusions and the main problems in the project are obtained, and the relevant recommendations are put forward in combination with these problems. In order to carry out the research results of this paper, this study applies scientific analysis method to the decision making of the coal fired thermal power project, to the preparation work before the construction, to the design of the construction process. Based on the analysis of the evaluation elements of coal-fired thermal power expansion project, the evaluation index system and matter-element extension evaluation model are constructed, and the special heating construction of the project is analyzed through an example. Comprehensive research and evaluation of cogeneration benefit, expansion area development, pollutant treatment and sustainable supply of production materials are carried out to find out the defects and advantages of the project, sum up the experience and lessons, and provide the basis for the decision of the following similar projects. Improve project management level.
