Simple gas turbine performance model for various types of combined cycle power plants (Calibration of the model by the simple cycle data)

Recently, gas turbines have been used as key components of a variety of combined cycle power plants including integrated coal gasification combined cycle and humid air turbine etc., and their characteristics strongly influence the total performance of these power plants. The purpose of this article is to demonstrate the usefulness of a relatively simple model of gas turbine performance, which is commonly applicable to modern air-cooled high temperature gas turbines. Gas turbine performance in such combined cycles can be estimated with the model calibrated by the simple cycle data of the turbine.
