摘要: 火力发电厂辅助设备可靠性水平是影响机组安全性能的重要因素,建立辅机可靠性评价体系对提升设备管理水平至关重要,辅机可靠性指标种类繁多且相互关联,有因果关系,也存在隶属关系,有频次指标,也有时间指标,通过层次分析法和模糊综合评价法相结合,建立了包括目标层、管理层、设备层的递进多层次评价模型和体系,实现了对辅助设备可靠性全面、准确、综合的定量评价。选取国华电力4个发电公司12台机组共186台辅助设备进行实证分析,验证了评价模型的科学性和合理性。

Abstract: The reliabilities of the auxiliary equipments in thermal power plants are the major factors that affect the safety of the units. Therefore, it is important to establish an evaluation model to improve the management of the equipments. There are various and correlative indicators with cause-and-effect and subject relationships to evaluate the reliabilities, such as frequencies and times. In this paper, with the combination of the analytic hierarchy process(AHP) and the fuzzy comprehensive evaluation(FCE), the multi-level comprehensive evaluation model and system consisting of the goal level, the management level and the equipment level are established and the overall, precise and comprehensive quantitative assessment is obtained. In addition, the rationality of the model is verified by the practical evaluation on the 186 auxiliary equipments of 12 units from 4 power plants.

Key words: thermal power generation, auxiliary equipment, reliability, evaluation model
