【摘要】：随着经济发展和社会生产对绿色经济的迫切需要,大力发展清洁能源,已经成为电力行业发展的必然趋势。风电产业具有储量大、分布广、技术可靠的特点,已成为我国发展清洁能源的重要方向。但随着风电工程建设项目的快速发展,工程施工项目也越来越多,参与施工单位的质量管理水平也存在差异,因此,如何确保风电场施工质量就成为一个迫切需要解决的问题。风电机组的施工质量不仅关系到投资成本和运营成本,更关系到人民群众的生命和财产安全,因此,怎样对风电工程的施工质量进行管理,在投资成本、施工工期、自然环境等因素的制约下,切实提高整个工程的施工质量,是摆在我们面前的一个十分重要的课题。由于风电场建设涉及到的工作内容多而且杂,不仅有房屋建设,还有道路铺设;不仅有大型吊装,还有弱电控制系统调试;不仅有架空线路,还有地埋电缆敷设,不一一列举,本文通过节选大型混凝土浇筑、风机吊装、变电站安装调试三个最主要的工程,运用质量控制的原理,结合大唐闽侯青林风力发电场工程建设项目的特点,对风电场工程建设重点施工项目施工质量评价及管理的研究,对该工程在施工过程中出现的混凝土浇筑中出现的冷缝、磨面、蜂窝等质量问题进行深入分析,风力发电机组吊装过程中容易出现的险情进行总结,结合电力系统风力发电机组易出问题的内容,有针对性的进行分析,针对变电站系统及控制系统相关电缆、盘柜等安装调试中出现的问题进行汇总分析,找出这些问题产生的原因,有针对性的制定方案和措施,进一步提高施工质量,为巩固质量控制的成果,从制度、标准、流程等方面,强化执行,保障质量控制取得实效。本文共分四章,第一章,简要介绍了风电场施工质量控制研究的背景和意义,第二章介绍福建闽侯青林风电场的概况,运用鱼刺图、直方图分析人、机械、材料、工艺、环境对施工质量的影响情况,从而找出影响混凝土浇筑、风机吊装、变电站安装质量的关键原因。第三章针对分析的原因,制定这三个主要工作的施工方案,做好工程施工的过程控制。第四章提出了确保施工方案可靠施工的保障措施。最后得出结论,通过细化施工方案,完善质量保障措施,能够切实有效保证风电场建设项目的施工质量。
[Abstract]:With the urgent need of green economy in economic development and social production, the development of clean energy has become an inevitable trend in the development of electric power industry. Wind power industry has the characteristics of large reserves, wide distribution, reliable technology, and has become an important direction of clean energy development in China. However, with the rapid development of wind power engineering construction projects, more and more engineering construction projects, participating in the quality management of construction units are also different, so how to ensure the construction quality of wind farms has become an urgent problem to be solved. The construction quality of wind turbine is not only related to the investment cost and operation cost, but also to the life and property safety of the people. Therefore, how to manage the construction quality of wind power project, in the investment cost and construction period, Under the restriction of natural environment and other factors, it is a very important task for us to improve the construction quality of the whole project. Since the construction of wind farms involves many and miscellaneous tasks, not only houses but also roads are laid; there are not only large lifting installations, but also commissioning of weak electricity control systems; not only are there overhead lines, but also buried cables are laid, not to mention them. In this paper, by selecting three main projects of large concrete pouring, blower hoisting, substation installation and commissioning, and applying the principle of quality control, combined with the characteristics of the construction project of Minhou Qinglin wind farm in Datang, The evaluation and management of construction quality of key construction projects of wind farm engineering are studied. The quality problems such as cold joint, abrasive surface, honeycomb and so on, which appear in concrete pouring in the construction process of the project, are deeply analyzed. In the process of wind turbine hoisting, the dangerous situation is summed up, combined with the content of the wind turbine in power system, the analysis is carried out pertinently, aiming at the relevant cables of substation system and control system, Collecting and analyzing the problems in the installation and commissioning of cabinets, finding out the causes of these problems, formulating relevant plans and measures to further improve the construction quality, in order to consolidate the achievements of quality control, from the system, standards, Process and other aspects, strengthen implementation, ensure quality control to achieve practical results. This paper is divided into four chapters. The first chapter briefly introduces the background and significance of wind farm construction quality control research, the second chapter introduces the general situation of Fujian Minhou Qinglin wind farm, using fish burr diagram, histogram analysis of people, machinery, materials, technology, The influence of environment on the quality of construction is discussed, and the key factors affecting the quality of concrete pouring, blower hoisting and substation installation are found out. In the third chapter, according to the reasons of the analysis, the construction scheme of the three main works is formulated and the process control of the project construction is done well. The fourth chapter puts forward the guarantee measures to ensure the reliable construction of the construction scheme. Finally, it is concluded that the construction quality of the wind farm construction project can be effectively guaranteed by refining the construction scheme and perfecting the quality assurance measures.
