预测性维修技术在核电厂的应用研究

Study on Application of Predictive Maintenance Technology in Nuclear Power Plant

为保障核电厂机组的安全稳定经济运行,核电企业逐步引入基于设备状态的预测性维修(PdM)。本文基于某核电厂的生产实践,对PdM技术的发展应用情况及在核电厂实际应用过程中面临的挑战进行了探讨,指出考虑到核设备的复杂性和特殊性,在应用PdM技术时,应根据设备的分级情况、设备失效机理和PdM技术自身的成熟度合理选择不同的维修策略;同时还应注意收集和分析设备的数据信息以便优化PdM技术,从而获得满意的设备管理结果。

In order to ensure the safe,stable and economic operation of nuclear power plant units,nuclear power enterprises have gradually introduced predictive maintenance(PdM)based on equipment status.Based on the production practice of a nuclear power plant,this paper discusses the development and application of PdM technology and the challenges faced in the practical application of PdM technology in nuclear power plants,and points out that in consideration of the complexity and particularity of nuclear equipment,when applying PdM technology,different maintenance strategies shall be reasonably selected according to the classification of equipment,the failure mechanism of equipment and the maturity of PdM technology itself;at the same time,attention shall also be paid to the collection and analysis of equipment data information in order to optimize predictive maintenance technology,so as to obtain satisfactory equipment management results.
