Method for performing gas turbine performance diagnostics
First Claim
1. A method of performing diagnostics on a system comprising:
- receiving a plurality of measurement parameters, each corresponding to one of a plurality of parameters at a time k;
forming a deviation vector from said plurality of measurement parameters;
calculating an initial deviation vector from an initial fault vector;
calculating a multiple fault isolation deviation vector using said initial deviation vector and said deviation vector;
determining if an event is in progress;
performing statistical data validity to set a present inhibit flag and a past inhibit flag if said event is not in progress; and
performing module performance analysis based upon said multiple fault isolation deviation vector according to said present inhibit flag and said past inhibit flag if said event is not in progress.

Abstract
A method of performing diagnostics on a system comprises receiving a plurality of measurement parameters, each corresponding to one of a plurality of parameters at a time k, forming a deviation vector from the plurality of measurement parameters, calculating an initial deviation vector from an initial fault vector, calculating a multiple fault isolation deviation vector using the initial deviation vector and the deviation vector, determining if an event is in progress using the multiple fault isolation deviation vector, performing statistical data validity to set a present inhibit flag and a past inhibit flag, and performing module performance analysis according to the present inhibit flag and the past inhibit flag.
