SYNTHETIC EVALUATION ON CONDITIONS OF EQUIPMENT IN POWER PLANT BASED ON FUZZY JUDGMENT AND RCM ANALYSIS

Aiming at the problem that the equipment in power plant are complex and difficult to evaluate their conditions accurately,a synthetic evaluation method on conditions of equipment in power plant based on fuzzy judgment and RCM analysis is proposed on the basis of system division and characteristic condition parameter extraction. By fully using the operating parameters, condition monitoring parameters and statistic operation parameters, the conditions of system and equipment are preliminarily evaluated.Then the knowledge deduction is done based on RCM analysis data, and the failure modes and positions are identified. It is shown by the instance that this method is feasible and effective, and the evaluated results can be used as a support next in making scientific maintenance decisions.
