ABSTRACT:
This report presents the results of reliability and availability assessments performed with the cooperation of seven utilities operating combined-cycle power plants in service since 1974 to evaluate:
• Combined-cycle unit equivalent availability and equivalent forced outage rates
•
mean downtime (MDT)
• Gas turbine reliability correlations with service hours, starting frequency, fuel type, and service factor
A data base was developed for 45 plant components or systems for the period 1978 through 1980; this led to recommendations for improving outage data collection for the purpose of reliability analyses. In addition reliability, availability, and maintainability prediction models for several commercial combined-cycle plant designs were developed and validated.
