【摘要】：“经济发展,电力先行”,体现出电力行业对社会发展的重要性,提供安全、经济、清洁、可持续的电力供应,是电网公司做出的最好保证,满足国家各行各业的发展、保障了居民的生活。现阶段,我国的电网建设的投资总额逐步增大,即输变电工程项目批复数量逐步增多。但输变电项目从可研、立项、施工阶段、竣工验收、运行的全过程,缺乏全过程管理总体评价管控。输变电项目后评价是项目周期管理中极其关键的一环,后评价工作将客观、系统的对投运的输变电项目开展分析评价,分析项目的实际成果与预期目标的差异,归纳出项目施工过程的薄弱环节,并提出相应的意见,从而为后续的输变电项目的实施提供决策性的建议,从而提高电网建设项目的整体投资效益。实施输变电项目后评价不仅满足电网企业的需求,还满足电网健康发展的要求。通过后评价工作,能提升电网发展的速度,优化电网结构,提高供电可靠性,降低电网运行成本,最终提高国家的整体投资收益率。本论文以项目后评价为出发点,以项目后评价理论为基础,以模糊层次分析法和灰色关联度分析法为主要手段,并结合输变电项目的特征,着重说明输变电项目后评价的内容及其目的。按照项目的前期资料,叙述国内外对项目后评价工作的研究成果,简要介绍项目后评价工作的相关理论,主要包含开展项目后评价工作的研究意义、开展方法、构建思路、后评价目标、后评价内容。按照后评价步骤,构建应用性强、合理性高的输变电项目后评价指标体系及评价模型,并给出评价标准。最后以110kV九龙输变电项目为实证开展分析,首先对110kV九龙输变电项目的情况进行总体叙述,对项目的设计规模、建设情况、运行情况进行简要说明。然后根据构建指标体系的原则,按照指标构建步骤,结合输变电项目自身结构的复杂性特点,通过查阅大量文献资料,采用分层法,将指标体系分成多层,逐层细化总目标,并结合专家意见和输变电项目的特点,初步确定了原始评价指标,在保证后评价初始指标体系的全面性的同时,解决指标的局限性、重叠性、代表性差等问题,采用灰色关联分析法对输变电项目后评价开展指标筛选,得到输变电项目后评价最终指标。对确定的10项一级指标、30个二级指标,按照模糊层次分析法的操作步骤,两两比较各指标要素,得到判断矩阵与相应的权重值,并逐项对分目标层中的四个阶段开展后评价工作,最终形成110kV九龙输变电项目的总体后评价结果。通过案例的实施,验证论文所构建的指标体系及其模型的科学性、实用性,从而丰富了输变电项目后评价的相关理论,为输变电项目后评价体系的深入研究提供有意的参考,进一步提升供电企业管理水平和经济收益,为后续的输变电项目的实施提供决策性的建议和借鉴。
[Abstract]:"Economic development, electric power first" reflects the importance of the power industry to social development. Providing safe, economic, clean and sustainable power supply is the best guarantee made by power grid companies to meet the development of various industries in the country. The life of the residents is safeguarded. At present, the total investment in power grid construction in China is gradually increasing, that is, the number of approval for transmission and transformation projects is gradually increasing. However, the whole process of power transmission and transformation project from research, project establishment, construction stage, completion acceptance, operation, lack of overall evaluation and control of the whole process management. Post evaluation of transmission and transformation projects is an extremely critical part in project cycle management. The post evaluation work will be objective, systematic analysis and evaluation of the transmission and transformation projects in operation, and analysis of the differences between the actual results of the projects and the expected objectives. The weak links in the construction process of the project are summarized and the corresponding opinions are put forward so as to provide decision-making suggestions for the implementation of the subsequent power transmission and transformation projects and thus to improve the overall investment benefit of the power grid construction projects. The post-evaluation of transmission and transformation projects not only meets the needs of power grid enterprises, but also meets the requirements of the healthy development of power grid. Through the post evaluation work, it can improve the speed of power grid development, optimize the power network structure, improve the reliability of power supply, reduce the operation cost of the power network, and finally raise the overall investment return rate of the country. This paper takes post-project evaluation as the starting point, based on the theory of post-project evaluation, takes fuzzy analytic hierarchy process and grey correlation analysis as the main means, and combines the characteristics of transmission and transformation projects. The content and purpose of post-evaluation of transmission and transformation project are emphasized. According to the preliminary data of the project, this paper narrates the research results of the post-evaluation work at home and abroad, briefly introduces the relevant theories of the post-evaluation work of the project, mainly includes the research significance, the method and the train of thought of carrying out the post-evaluation work of the project. Post-evaluation objective, post-evaluation content. According to the post-evaluation steps, a post-evaluation index system and evaluation model for power transmission and transformation projects with strong application and high rationality are constructed, and the evaluation criteria are given. Finally, taking the 110kV Jiulong transmission and transformation project as an empirical analysis, the paper first describes the overall situation of the 110kV Kowloon transmission and transformation project, and briefly explains the design scale, construction situation and operation of the project. Then according to the principle of constructing index system, according to the steps of index construction, combined with the complexity of transmission and transformation project structure, through consulting a lot of literature and adopting stratification method, the index system is divided into multiple layers, and the overall goal is refined layer by layer. Combined with the expert opinion and the characteristics of the transmission and transformation projects, the original evaluation indexes are preliminarily determined. While ensuring the comprehensiveness of the initial index system of post-evaluation, the problems of limitation, overlap and poor representativeness of the indicators are solved. The final indexes of post evaluation of transmission and transformation projects are obtained by using grey relational analysis method to carry out index screening for post evaluation of transmission and transformation projects. According to the operation steps of Fuzzy Analytic hierarchy process (FAHP), the 10 primary indexes and 30 secondary indexes are determined and the index elements are compared, and the judgment matrix and the corresponding weight values are obtained. The post-evaluation work is carried out one by one in four stages of the target layer, and the overall post-evaluation results of the 110kV Jiulong Power Transmission and Transformation Project are finally formed. Through the implementation of the case, the paper verifies the scientific nature and practicability of the index system and its model, which enriches the relevant theories of post-evaluation of transmission and transformation projects, and provides an interesting reference for the in-depth study of post-evaluation system of transmission and transformation projects. Further improve the power supply enterprise management level and economic benefits, for the subsequent implementation of transmission and transformation projects to provide decision-making advice and reference.
