Fault prediction method for plant

Abstract

Disclosed is a method of predicting a plant fault including: defining a rotary machine elements for predicting a fault determination among plant components; defining a fault type and a fault condition of each of the rotary machine elements; classifying and coding the fault condition of the rotary machine element into a fabrication and installation condition, a load condition, a lubrication condition, and an environment and operation condition; associating the fault type of the rotary machine element with code values of the four fault conditions and storing the association in a database; receiving status information on the fault condition of the rotary machine element for predicting a fault from a user; and determining the fault type corresponding to a combination of the code values of the received fault conditions. Complex factors in the fault possibly caused in the plant is predicted more clearly beyond simple defect detection.
