Abstract :
In this paper, an on-line deterioration prediction method and residual life evaluation are proposed for maintenance of rotating equipment. Status of the rotating equipment is inspected by vibration measurement and a mathematical model for the deterioration of the equipment is derived in order to predict future condition of the rotating equipment. For the construction of the deterioration model, outliers in the vibration data caused by measurement errors and so on are eliminated in order to improve accuracy of the deterioration model. Residual life of the rotating equipment is evaluated from the deterioration prediction by using the deterioration model. The effectiveness of the proposed deterioration prediction method and residual life evaluation are assured by actual data of rotating equipment in thermal power plants.
