Abstract:
1. An apparatus for monitoring gas turbine system performance comprising: a sensor module adapted to sense a plurality of gas turbine operating parameters and temperature measurements during the operation of said gas turbine system, wherein said gas turbine system comprises a plurality of combustor cans; a data analysis module adapted to receive said plurality of gas turbine operating parameters and temperature measurements to generate at least one actual swirl value and at least one predicted swirl value; a statistic calculation module adapted to receive said at least one actual swirl value and said at least one predicted swirl value and to generate at least one failure test statistic; and a failure detection module adapted to receive said at least one failure test statistic and to generate at least one failure flag signal, wherein said at least one failure flag signal indicates a presence of a failed combustor can in said plurality of combustor cans.
