Software for monitoring and evaluating the performance of gas turbines is being developed under the auspices of Gas Research Institute (GRI). Reference  provides an overview of the GRI project.
This paper describes the PEGASUS software and monitoring system. PEGASUS is an acronym for Performance Evaluation of GAS Users Systems. Field test results, on multi-shaft turbines used in the gas pipeline industry, have demonstrated the potential of the software. The software and instrumentation, can help identify maintenance and upgrade actions to improve performance.
