【摘要】：机组大修是电力企业生产的一个重要时期,有大量的施工人员进入作业现场参加紧张有序的检修和试验作业,由于机组检修工作作业多、区域分散,安全质量管理所面临的问题也就多且散,随着检修的进展,工作人员的精神状态变化也是一个不确定因素,这些都给机组大修的安全质量管理带来很大的困难,因此做好机组大修安全质量管控工作对发电厂的经济效益和社会效益都具有重要意义。本论文从绥中电厂1000MW超超临界机组大修的基本项目出发,根据电厂实际情况制定了详细的检修方案和安全、进度、质量管控措施,以能够准确衡量机组大修安全质量为目标,建立了一套简单、实用的安全质量评估体系。机组大修后热态评价表明机组大修后质量方面达到了优的标准,锅炉效率和汽轮机效率都有提高；厂用电率、空预器漏风率都有所降低,供电煤耗大约降低3g/kwh。大修过程中安全管理、物资、费用等方面也都达到优的标准。
[Abstract]:Unit overhaul is an important period in the production of electric power enterprises. A large number of construction personnel have entered the work site to participate in the intensive and orderly maintenance and test work. Due to the large number of unit maintenance work, the area is scattered. The problems faced by safety quality management are also numerous and scattered. With the progress of maintenance, the change of staff mental state is also an uncertain factor, which brings great difficulties to the safety and quality management of unit overhaul. Therefore, it is of great significance for the economic and social benefits of the power plant to control the safety and quality of unit overhaul. Starting from the basic project of overhauling of 1000MW ultra supercritical unit in Suizhong Power Plant, according to the actual situation of the power plant, the detailed overhaul scheme, safety, schedule and quality control measures are worked out in this paper, with the aim of accurately measuring the safety quality of unit overhaul. A set of simple and practical safety quality assessment system is established. The hot state evaluation of the unit after overhaul shows that the quality of the unit after overhaul has reached the excellent standard, the efficiency of boiler and steam turbine has been improved, the power consumption rate and air leakage rate of air preheater have been reduced, and the coal consumption of power supply has been reduced by about 3 g / kwh. Safety management, materials, cost and other aspects of the overhaul process are also up to the best standards.
