High-Reliability Combined-Cycle Program study. Final report. [170 units for 5-1/2 years]

Technical Report ·
OSTI ID:5288951
Operational data from a fleet of gas turbine power plants reporting under the General Electric Operational Reliability Analysis Program were evaluated. The evaluation was limited to data related to those events which caused the gas turbine to be shut down from an operational condition. From the evaluation the systems and components that are the largest contributors to forced outage events and forced outage downtime were determined. This determination is useful in establishing priorities for achieving improvements in the forced outage performance for future design gas turbine power plants. From an evaluation of the effects of service hours on plant performance, it was concluded that high-service-hours plants are more reliable than low-service-hours plants. Reliability determination techniques were developed for utilizing forced outage data to evaluate the relative merits of different system design alternatives. Additionally, reliability goals were established for a new design plant, fundamental causes of unreliability were identified, and several programs for improving the reliability of the next generation gas turbine plant were identified. 6 figs., 11 tabs.
