More Information
Summary:A method (300, 400) for monitoring the health of a compressor of a gas turbine is disclosed. The method (300, 400) includes receiving a plurality of turbine data points (302, 402), wherein the plurality of turbine data points may include one or more operating parameters, at least one of a computer discharge temperature (CTD), and one or more performance parameters. The plurality of turbine data points may be categorized based on the one or more operating parameters (304, 404). A statistical variability measure of at least one of the CTD (306,406) and the one or more performance parameters may be computed for each of the plurality of bands. An alarm indicator (308, 408) may be computed based on the at least one statistical variability measure. The method may also include combining two or more of the operating parameters, the CTD and the performance parameters using sensor fusion techniques. The alarm indicator may be computed based on the combined parameters.
