This paper describes the application of an adaptive predictive expert (ADEX) control solution to the attemperation process for superheated steam temperature control in the ScottishPower coal-fired power station at Cockenzie near Edinburgh in Scotland. The project comprised two phases, the first of which was a trial to establish the feasibility and potential benefits of ADEX compared with the ex...

To facilitate daily cycling of large electric generating units that were originally designed for baseload operation, the control system has to be redesigned for plant maneuverability over the operating range. A methodology for synthesizing an integrated feedforward–feedback control (FF/FBC) strategy is proposed for wide-range robust control of commercial-scale steam-electric power plants. In th...

This paper deals with the state and unmeasured disturbance estimation within the nonlinear model predictive control of the superheated steam temperature in a once-trough boiler of a fossil fuelled power plant. The nonlinear model of the once-trough boiler has very high order, it is significantly nonlinear and load dependent. Model is excited by several disturbances, but not all of them are meas...

The gas-steam power plant combines a gas and steam plant, where Heat Recovery Steam Generator (HRSG) is unit for generating steam. waste heat from this system channelled to the chimney with Thermoelectric (TEG) module generate electrical energy. TEG uses thermal conduction process wall, height, diameter, velocity variables are considered analysis. To optimize analysis, we used dimensional analy...

Environmental and economic objective functions are used simultaneously to select the operating conditions of a steam and power plant. Different methodologies to solve bi objective optimization problems were implemented successfully. The life cycle potential environmental impact and the operating cost of the utility plant are minimized simultaneously. A methodology is presented to estimate the p...
