【摘要】：抽水蓄能电站的设备检修,是发电设备安全、经济运行,发电设备利用率提高,设备潜力被充分发挥的重要措施,是设备全过程管理的一个重要环节。由于计划检修模式存在的一系列问题,随着国内外大型设备检修模式的改进,水电机组检修开始采用状态检修的模式。实践证明发电设备的状态检修相对过去多年实行的计划检修是先进的、经济的。对于国网新源下属众多的抽水蓄能电站,在现代高新技术的持续发展和应用的环境下,研究如何在抽水蓄能电站实施状态检修意义重大。本论文通过对新源系统抽水蓄能检修体制发展历史和现状的研究,指出计划检修的片面性与弊端,分析抽水蓄能电站状态检修的可行性；在总结了水轮机典型诊断故障基础上,详细分析了机组状态监测系统在水电机组运行状态评价、机组运行优化以及机组性能试验方面的应用案例；制定了抽水蓄能电站机组状态检修的具体实施流程和方案；提出实施状态检修的关键是要选择与布置合适的测点、构建机组状态在线监测系统、建立机组远程监测与诊断中心,为水电机组状态检修提供必要的技术手段,为设备状态检修提供科学决策依据。通过实施新源公司抽水蓄能设备检修标准化管理,必将提高整个新源公司生产设备的可靠性及生产管理水平。在取得成功经验后,可以在相应抽水蓄能设备检修管理方面加以推广应用。
[Abstract]:The equipment maintenance of pumped storage power station is an important measure for the safe and economical operation of the generating equipment, the improvement of the utilization ratio of the generating equipment and the full development of the equipment potential. It is also an important link in the management of the whole process of the equipment.Due to a series of problems existing in the planned maintenance mode, with the improvement of the maintenance mode of large equipment at home and abroad, the maintenance of hydropower units began to adopt the mode of condition-based maintenance.It is proved by practice that the condition based maintenance of power generation equipment is advanced and economical compared with the planned maintenance implemented in the past years.Under the environment of the sustainable development and application of modern high technology, it is of great significance to study how to implement condition-based maintenance in pumped storage power stations.Based on the research on the history and present situation of pumped storage maintenance system in Xinyuan system, this paper points out the one-sidedness and malpractice of planned maintenance, analyzes the feasibility of condition maintenance of pumped storage power station, and summarizes the typical fault diagnosis of hydraulic turbine.The application cases of unit condition monitoring system in operation condition evaluation, unit operation optimization and unit performance test are analyzed in detail, and the concrete implementation flow and scheme of condition maintenance for pumped storage power station unit are established.The key to implement condition-based maintenance is to select and arrange suitable measuring points, to construct on-line monitoring system of unit status, and to establish remote monitoring and diagnosis center for hydropower units, which provides necessary technical means for condition maintenance of hydropower units.It provides scientific decision basis for equipment condition maintenance.Through the implementation of the standardized management of the maintenance and repair of the pumped storage equipment in Xinyuan Company, the reliability and production management level of the whole production equipment will be improved.After the successful experience, it can be popularized and applied in the maintenance management of the corresponding pumped storage equipment.
