A 32nd order boiler-turbine model is developed to solve the optimal set-point scheduling problem for main and hot reheat steam conditions in a 235 MW gas fired electric generating plant. The optimization strategy uses control vector parameterization in which the boiler controller set-point function generators are modified to produce suboptimum signals. Constraints in the process variables are monitored by critical alarm limits, and hoop stresses in the heat exchanger tubes are estimated as well. Preliminary plant tests indicate these estimated savings may be realistic. The boiler-turbine model and optimization strategy illustrate the potential use of mathematical models for power plants.
