Abstract

The current paper presents a review of literature on the performance of the Combined Cycle Gas Turbine (CCGT) Power Plant. Focus is placed on the modelling of CCGT and optimization techniques. Available literature emphasizes the importance of CCGT as an effort to increase the efficiency of Gas Turbines (GT) through heat recovery. Using standard models that have wide consensus, the review highlights on various factors that affect the performance of CCGT. Performance, as measured by relative efficiency, is viewed as the ability to effectively use existing resources optimally. The review notes several optimization techniques based on existing and new models including operational, design, and environmental factors.
