System and method for predicting turbine rub

摘要

A system for predicting turbine rub includes a monitoring system configured to form operational values for a turbine based on information received from the turbine and a correlation engine configured to form at least one correlated value from the operating values that correlates a first operating value to a second operating value. The system also includes a variable deriver configured to form at least one derived variable from a one of the operating values and a rub predictor that forms a rub prediction based on the at least one correlated value and the at least one derived value.
