Process for adapting measurement suite configuration for gas turbine performance diagnostics

摘要

A method and system is described that estimates gas turbine engine module performance changes from gas path measurement data using a linear predictor-corrector estimation process. A measurement configuration matrix M_C and a fault configuration F_C matrix are assembled. The configuration matrices M_C and F_C are used to adapt a typical linear predictor-corrector type of performance estimation process to a given measurement suite and are ideally suited for linear estimation systems such as those using a Kalman filter.
