摘要： A system and method for anomaly detection is provided. The system (100) and method (200) include utilizing one or more processors, such as in a server, for receiving (108) operational and dynamics data (104) from sensors associated with devices (102), filtering the data, establishing a set of baseline dynamics data and eliminating data dependencies (110). The system and method further include generating an expected level of data variation (112), identifying an anomaly based on a deviation of the device data from the baseline data normalized by the expected level of data variation (114), optionally correlating an anomaly with potential causes, and providing an output indicating an anomaly (116).

摘要： A fuel, an oxidant, and a diluent can be introduced to a combustion zone, wherein the oxidant comprises air, oxygen-enriched air, or oxygen-lean air. At least a portion of the fuel can be combusted to produce an exhaust gas comprising, nitrogen, nitrogen oxides, and carbon monoxide. The exhaust gas can be expanded to produce mechanical power and an expanded exhaust gas. A concentration of at least one of oxygen, hydrogen, nitrogen oxides and carbon monoxide, in the exhaust gas or the expanded exhaust gas or both can be determined, and an amount of the oxidant or the fuel introduced to the combustion zone, or both, can be adjusted based on the determined concentration to produce an exhaust gas containing a combined amount of oxygen and carbon monoxide of less than about 2 mol % and a nitrogen concentration ranging from 20 mol % to 75 mol %. The diluent to the combustion zone can include at least a portion of the exhaust gas containing a combined amount of oxygen and carbon monoxide of less than 2 mol % and a nitrogen concentration ranging from 20 mol % to 75 mol %.

摘要： The present invention comprises systems and methods for determining stability margin of a combustor. One embodiment of the present invention includes the steps of providing a measuring device in communication with the combustor, wherein the measuring device generates signals indicative of combustor quantities; performing an autocorrelation calculation on the signals to determine the correlation time of the signals in the combustor; and determining the damping coefficient from the autocorrelation calculation, wherein the damping coefficient signifies a proximity of the combustor to instability. The damping coefficient may be estimated from the oscillatory envelope of the autocorrelation calculation data.
