Two control strategies were evaluated for a new type of electric power plant as part of a large utility network. An entrained coal gasifier fuels a gas turbine/steam turbine combined-cycle unit forming the integrated plant which was simulated by computer to analyze alternative control strategies. Transient operation of this gasification-combined-cycle (GCC) plant was studied to determine open-loop response as a stand-alone plant, as well as closed-loop response while functioning in a typical utility power system. GCC plant performance during specified operating contingencies, such as equipment trip or emergency shutdown, was also studied. This volume presents the model descriptions for the Texaco entrained gasifiers, Selexol unit, oxygen plant, scrubber, ammonia absorber, water balance, combustion turbine-generator and gas-turbine controls, heat recovery steam generators, steam turbine-generator and steam-turbine controls, fuel gas expander, power system, and station controller.
