Turbine performance diagnositic system and methods

摘要

A turbine performance diagnostic system (50) 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.
