【摘要】：电力行业作为国民经济发展的基础性行业,为我国经济与社会的发展、满足人民日益增长的需求提供强大的驱动力。面对日益增长的社会电力负荷需求,各大电力企业与国家电网积极进行大规模建设,不断提高发电能力与电力输配送能力,其中关键的一环就是输变电工程项目的建设。合理的输变电工程项目可以保证电能以最有效的方式输送到负荷区域,同时可以满足节约成本、保护环境、保证电能持续稳定输送等目标。对输变电工程项目实施情况进行科学的综合评价,有利于衡量项目的整体施工情况,并能为后续工程项目实施提供决策依据。兴化兴西110千伏输变电工程项目是为满足区域乃至社会电力负荷需求,优化电网结构,减少网络损耗,提高供电质量和可靠性能,最终提升国民经济效益等需要而建设的。本文首先介绍了论文的研究背景、意义以及相关的综合评价理论,然后介绍兴化地区的电力系统现状和兴化兴西110千伏输变电工程项目的基本情况,包括设计原则、建设规模以及新技术的应用;接着根据兴化市电网规划的现状和目标,在综合考虑项目评价指标体系的构建准则之后,从经济、技术、社会三个方面建立了兴化兴西110千伏输变电工程项目评价的指标体系;然后,本文针对兴化兴西输变电工程项目建立全面系统的评价模型;最后,通过以熵权为基础理论来合理分配权重并结合TOPSIS方法对本项目做了进一步的评估研究,论证出该方法的可行性。兴化兴西110千伏输变电工程项目在技术可行性,经济可行性,社会可行性等方面均达到了电力项目建设要求,并且根据本文我们可以证明,采用的以熵权为基础理论确定权重的TOPSIS方法对输变电工程能够实施有效的系统的全面评估,并且为投资决策者做出正确决策奠定了一定的基础。
[Abstract]:As the basic industry of national economic development, the electric power industry provides a powerful driving force for the development of our economy and society, and to meet the increasing needs of the people. In the face of the increasing demand of social electric power load, the major power enterprises and the State Grid actively carry out large-scale construction and continuously improve the power generation capacity and power transmission and distribution capacity, among which the key link is the construction of transmission and transformation projects. The reasonable transmission and transformation project can ensure that the electric energy can be transported to the load area in the most effective way, at the same time, it can meet the goals of saving the cost, protecting the environment and ensuring the continuous and stable transmission of the electric energy. A scientific comprehensive evaluation of the implementation of power transmission and transformation projects is helpful to measure the overall construction situation of the project and to provide a basis for decision making for the implementation of subsequent projects. Xinghua Xingxi 110 kV transmission and transformation project is built to meet the demands of regional and social electric power load, optimize the power network structure, reduce network loss, improve the quality and reliability of power supply, and finally enhance the efficiency of the national economy. This paper first introduces the research background, significance and related comprehensive evaluation theory of the paper, then introduces the current situation of power system in Xinghua area and the basic situation of the power transmission and transformation project of Xinghua Xingxi 110kV power transmission and transformation project, including the design principles. Scale of construction and application of new technologies; Then according to the present situation and goal of Xinghua power network planning, after considering the construction criteria of project evaluation index system, the evaluation index system of Xinghua Xingxi 110 kV transmission and transformation project is established from three aspects of economy, technology and society. Then, this paper establishes a comprehensive and systematic evaluation model for Xinghua Xingxi transmission and transformation project. Finally, the feasibility of this method is demonstrated by the rational distribution of weights based on entropy weight and the further evaluation and study of this project with TOPSIS method. Xinghua Xingxi 110 kV transmission and transformation project has met the requirements of electric power project construction in terms of technical feasibility, economic feasibility, social feasibility, etc., and according to this paper, we can prove that, The TOPSIS method, which is based on the entropy weight theory to determine the weight, can carry out the comprehensive evaluation of the transmission and transformation engineering effectively, and it lays a certain foundation for the investment decision makers to make the correct decision.
