Abstract: A system and computer-implemented method for monitoring and diagnosing anomalies in a wheel-space of a gas turbine is implemented using a computer device coupled to a user interface and a memory device and includes storing a plurality rule sets in the memory device, the rule sets relative to the wheel-space, the rule sets including at least one rule expressed as a relational expression of a real-time data output relative to a real-time data input, the relational expression being specific to a temperature of the wheel-space. The method also includes receiving real-time and historical data inputs from a condition monitoring system associated with the gas turbine, the data inputs relating to sources providing heat to the wheel-space and estimating a wheel-space temperature value using the inputs relating to a temperature of the wheel-space.

Abstract: A system and method for monitoring and diagnosing anomalies in an output of a gas turbine, the method including storing a plurality rule sets specific to a performance of the gas turbine. The method further including receiving real-time and historical data inputs relating to parameters affecting the performance of the gas turbine, periodically determining current values of the parameters, comparing the initial values to respective ones of the current values, determining a degradation over time of the at least one of the performance of the compressor, the power output, the heat rate, and the fuel consumption based on the comparison, recommending to an operator of the gas turbine a set of corrective actions to correct the degradation.
