1. A computer-implemented method for monitoring and diagnosing combustion anomalies in an operation of a gas turbine, the method implemented using a computer device coupled to a user interface and a memory device, the method comprising:
storing a plurality rule sets in a memory device, the rule sets relative to the operation of the gas turbine, the rule sets comprising 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 at least one of a temperature spread of an exhaust flow of the gas turbine, a swirl angle of the exhaust flow, a health of a plurality of secondary flame detectors of the gas turbine, and a transfer of the gas turbine from a first mode of operation to a second lower NOX mode of operation; receiving real-time and historical data inputs from a condition monitoring system associated with the gas turbine, the data inputs relating to parameters affecting at least one of the temperature spread of the exhaust flow of the gas turbine, the swirl angle of the exhaust flow, the health of the plurality of flame detectors of the gas turbine, and the transfer of the gas turbine from the first mode of operation to the second lower NOX mode of operation; determining a fuel gas line pressure drop using the received data; comparing the determined pressure drop to a predetermined threshold range; and recommending to an operator of the gas turbine to transfer the mode of operation of the gas turbine from the first mode to the second mode without reducing a load of the gas turbine if the determined pressure drop meets the predetermined threshold range. |
