A parametric study of gas turbine cycles for electrical power generation

Sales of industrial gas turbines have risen sharply recently, and it appears they may soon become the preferred method for base load power generation. This switch from more traditional powerplants is due to such factors as the gas turbine's high efficiency, small size and low emissions.; The purpose of this thesis is to analyze the performance of current state-of-the-art gas turbine power systems, using computer simulations. The major losses in real cycles are accounted for, and comparisons between program output and existing data are performed to check the validity of assumptions made.; Gas turbines examined include the well established aero-derivative and heavy frame single-shaft units, both in simple and combined cycle applications. Also analyzed is an older design currently re-entering the market, the reheat cycle gas turbine. Based on the performance data gathered, insights are made into the designs of current models, and the changes expected in future designs.
