An Analysis Procedure for the Validation of On-Site Performance Measurements of Gas Turbines

In order to ensure accuracy and credibility of an engine health monitoring system, it is vital that the measurements used in the analysis process be accurate. An analysis procedure has been developed to verify the accuracy of daily measurements taken from industrial gas turbines in the gas pipeline industry. The procedure has been extended to use the measurements to develop an engine health monitoring system for this class of equipment which is based solely on existing instrumentation. The method has been tested using field data from several gas pumping units and was found to be capable of isolating instrumentation problems and to correctly diagnose engine health deterioration.
