【摘要】：近年来,我国经济的发展稳步向前,居民生活质量不断的提高,伴随着电力的需求也日益增加。目前,许多省市的用电负荷也不断增长,部分地区的电力供应已经无法满足居民和企业的需求,由此大型超高压输变电工程的建设及投运势在必行,因为它具有显著改善电网结构、及时满足社会用电需求和促进地方经济发展等重要作用。国家也在大力着手于大型变电站的建设,以输变电工程为主要内容的电网建设也迎来快速的展的大好时机。输变电工程的建设需要大量的人力和物力,耗资甚大;这样庞大的工程在管理上要求也相对严格,输变电工程项目的规划设计、实施建设、使用都有不同的部门来完成;这样形成了的运营模式使得各部门要自成一体,各部门负责人只对自身环节负责,没有人对项目的整体投资和利益负责,这是在管理过程中存在的严重缺陷,对项目没有一个整体的全过程的总体评价。因此,在此环境条件下,大力开展输变电工程项目综合效益问题的分析及评价显得尤为重要,这也对提高我国输变电工程以及类似工程项目的管理水平有着重要的现实意义本文以沈南500kv输变电工程项目为背景,研究输变电工程项目综合效益评价。本文首先阐述了选题背景和意义,通过相关文献的查阅,系统了解了国内外输变电项目综合效益评价的研究现状,然后,对输变电项目综合效益评价相关的评价理论与方法进行了介绍,结合沈南输变电工程项目的特点以及效益评价的特点,选取了层次分析法和模糊综合评价方法对该工程项目进行综合效益评价;接着,介绍了沈南输变电工程建设规模并分析了工程建设的内容,然后从技术效益、经济效益、社会效益、节能降耗四个方面对该工程项目进行分析研究,并以此为基础构建了该项目综合效益评价的指标体系;最后,运用层次分析法计算各个指标的权重,根据选取的模糊综合评价方法对输变电工程效益进行综合评价,得出评价结果为良好,基于结果分析,反映了沈南输变电工程项目的可行性,并且具有良好的经济效益,同时符合节能降耗的要求。本文研究成果对电力工程项目的决策以及对推广电力工程项目提供了科学的依据,同时也有一定的借鉴意义。
[Abstract]:In recent years, the economic development of our country has been advancing steadily, the quality of life of the residents has been improved constantly, and the demand for electricity is also increasing day by day.At present, the power load of many provinces and cities is also increasing, and the power supply in some areas can no longer meet the needs of the residents and enterprises. Therefore, the construction and operation of large-scale ultra-high voltage power transmission and transformation projects are imperative.It plays an important role in improving the structure of power grid, meeting the demand of electricity and promoting the development of local economy.The country is also vigorously engaged in the construction of large substations, and the power grid construction, which takes the transmission and transformation projects as the main content, also ushered in a good opportunity for rapid development.The construction of transmission and transformation project needs a lot of manpower and material resources, and it costs a lot of money, so the management requirements of such a huge project are relatively strict, and there are different departments to complete the planning, design and implementation of the transmission and transformation project.The mode of operation formed in this way makes the departments themselves responsible for their own links, and no one is responsible for the overall investment and interests of the project. This is a serious defect in the management process.An overall evaluation of the whole process without a single project.Therefore, under this environment, it is particularly important to carry out the analysis and evaluation of the comprehensive benefits of transmission and transformation projects.It is also of practical significance to improve the management level of transmission and transformation projects and similar projects in China. This paper takes Shennan 500kv transmission and transformation projects as the background to study the comprehensive benefit evaluation of transmission and transformation projects.This paper first describes the background and significance of the topic, through the reference of relevant documents, systematically understand the domestic and foreign comprehensive benefit evaluation of transmission and transformation projects research status, and then,This paper introduces the theory and method of comprehensive benefit evaluation of transmission and transformation project, and combines the characteristics of Shennan transmission and transformation project and the characteristics of benefit evaluation.This paper selects the analytic hierarchy process and fuzzy comprehensive evaluation method to evaluate the comprehensive benefit of the project, then introduces the construction scale of Shennan power transmission and transformation project and analyzes the contents of the project construction, and then from the technical benefits, economic benefits,Four aspects of social benefit, energy saving and consumption reduction are analyzed and studied, and the index system of the comprehensive benefit evaluation of the project is constructed. Finally, the weight of each index is calculated by using the analytic hierarchy process (AHP).According to the fuzzy comprehensive evaluation method selected for comprehensive evaluation of transmission and transformation project benefit, the evaluation result is good. Based on the analysis of the result, it reflects the feasibility of Shennan transmission and transformation project, and has good economic benefit.At the same time meet the requirements of energy saving and consumption reduction.The research results in this paper provide a scientific basis for the decision-making of power engineering projects and the promotion of power engineering projects, and also have certain reference significance.
