【摘要】：随着我国国民经济持续稳定的快速发展,很多地区对电力需求进一步加大,为此,电网建设的力度也进一步加大,输变电工程就成为电网发展与建设的核心和重点。但由于输变电工程具有不同于其他工程的显著特点,该类工程点多、面广、战线长,极易受到地形、地貌、地质条件、地理环境、自然气候、生态环境等因素的影响,因而,若要使得输变电工程项目在保质保量的基础上得以顺利实施并达到预期的建设目标,就不仅需要对项目做好详细全面且深入的可行性研究,而且更需要在此基础上制定出科学合理正确有效地工程设计方案。但更重要的是,在获得多个设计方案的基础上,如何对它们进行科学的分析和评价,使各方案通过相互的比较和对比,能够相互补充与完善,积极汲取各自的优点而使工程设计方案更加的科学合理就更为重要。为此,本课题就此问题展开针对性研究。目前,对输变电工程设计方案的分析已属于常态化化工作,但各单位在分析的内容、分析的方法、分析的步骤、分析的指标等方面还存在很大的差异,为此,本课题在明确输变电工程的特点、在其实施中可能遇到的问题和风险以及输变电工程设计需考虑的内容、应遵守的原则等内容基础上,就如何把输变电工程设计作为一个整体项目,把项目管理的科学思想与科学方法引进来,如何对输变电工程设计方案进行更加科学的分析、评价和管理进行了深入系统的分析与探讨。并以朔州110KV输变电工程设计方案为例,在确定了输电工程设计方案的分析内容和输变电工程设计方案评价的基本准则、评价方法以及评价流程的基础上,结合朔州输变电工程的特点,确定了最重要的四个评价指标即投资效益、方案的科技含量、项目的成功度和对环境的影响。然后,对该工程进行了多方案的对比性分析和互斥性分析,按照输变电工程设计方案的评价流程对朔州输变电工程设计方案进行了实例评价,不仅为最终选出最为合理的方案提供了科学的依据,而且还根据分析结果,对朔州输变电工程的设计方案提出了若干改进建议。这一研究结果不仅对输变电工程设计方案的科学选择具有重要的价值,而且对及时发现设计中存在的问题、提高工程设计管理水平、节约项目投资、为工程项目的后期实施提供有力的保障也具有重要的意义。
[Abstract]:With the sustained and stable rapid development of our national economy, the demand for electricity in many areas has been further increased. Therefore, the power grid construction has been further strengthened, and transmission and transformation projects have become the core and focus of the development and construction of the power grid. However, because the power transmission and transformation projects are different from other projects, such projects have many points, wide scope, long front, easy to be affected by topography, geomorphology, geological conditions, geographical environment, natural climate, ecological environment, and so on. If the transmission and transformation project is to be carried out smoothly on the basis of quality and quantity, and to achieve the expected construction goal, it is necessary not only to do a detailed, comprehensive and in-depth feasibility study on the project. Moreover, it is necessary to work out a scientific, reasonable, correct and effective engineering design scheme on this basis. But more importantly, on the basis of obtaining a number of design plans, how to scientifically analyze and evaluate them so that they can complement and perfect each other through comparison and comparison. It is more important to learn their advantages to make the engineering design more scientific and reasonable. For this reason, this subject carries out targeted research on this issue. At present, the analysis of transmission and transformation engineering design scheme is a normal work. However, there are still great differences in the contents, methods, steps, indexes, etc., of the analysis, etc., for this reason, there are still great differences in the contents of the analysis, the methods of the analysis, the steps of the analysis, the indexes of the analysis, and so on. On the basis of defining the characteristics of transmission and transformation projects, the problems and risks that may be encountered in the implementation of transmission and transformation projects, and the contents to be considered in the design of transmission and transformation projects, as well as the principles to be observed, How to take transmission and transformation engineering design as an integral project, how to introduce scientific ideas and scientific methods into project management, and how to carry out more scientific analysis of transmission and transformation engineering design scheme, The evaluation and management are analyzed and discussed systematically. Taking the 110KV transmission and transformation project design scheme of Shuozhou as an example, the paper determines the analysis content of transmission engineering design scheme and the basic criteria, evaluation methods and evaluation flow of transmission and transformation engineering design scheme. Combined with the characteristics of Shuozhou Power Transmission and Transformation Project, the most important four evaluation indexes, namely, investment benefit, scientific and technological content of the project, project success degree and impact on the environment, are determined. Then, the multi-project comparative analysis and mutual exclusion analysis are carried out, and the design scheme of Shuozhou transmission and transformation project is evaluated by an example according to the evaluation process of the transmission and transformation project design scheme. It not only provides a scientific basis for selecting the most reasonable scheme, but also puts forward some suggestions for improving the design scheme of Shuozhou transmission and transformation project according to the analysis results. The results are not only of great value to the scientific selection of transmission and transformation engineering design schemes, but also to the timely discovery of design problems, the improvement of engineering design management level, and the saving of project investment. It is also of great significance to provide effective protection for the later implementation of the project.
