<P>PROBLEM TO BE SOLVED: To monitor performance and predict root causes of changes in the operation of turbines. <P>SOLUTION: A turbine performance diagnostic system 300 creates a performance report for one or more turbines 60 and includes an assessment module that receives operating data from at least one turbine and produces a performance report 70 from the operating data. The assessment module includes a change detection module 308 configured to determine when at least one parameter has changed beyond an associated threshold and generate an alarm, and a root cause analyzer 312 coupled to the change detection module that predicts a root cause of the alarm utilizing a Bayesian Belief Network (BBN). The performance report includes an indication of the predicted root cause. <P>COPYRIGHT: (C)2012,JPO&INPIT |
