Thermodynamic models suitable for use as diagnostic tools for pipeline gas turbines have been developed. A basic requirement was the prediction of the performance of gas turbines subject to in-service deterioration, including effects such as compressor fouling, foreign object damage, and turbine damage. This was met by creating thermodynamic models capable of operation over the complete running range expected, with a provision for introducing arbitrarily controlled degradations. Models for a variety of types of gas turbines currently in pipeline use have been tested, demonstrating good agreement with user experience. The models are extremely flexible in use and may be used either for investigation of specific problems or to increase user understanding of operating problems.
