Deterioration Prediction of Rotating Equipment Based on Vibration Measurement by Considering Data Reliability

Abstract

In this paper, a deterioration prediction method is proposed for maintenance of rotating equipment. Status of the rotating equipment is inspected by vibration measurement. A mathematical model of deterioration is introduced in order to predict future status of the rotating equipment. Defects of the rotating equipment are estimated by using the prediction using the mathematical model. For the construction of the mathematical model, outliers such as measurement errors are eliminated in order to improve accuracy of the mathematical model. The effectiveness of the proposed deterioration prediction method is assured by actual collected data of rotating equipment in thermal power plants.
