Multiobjective optimal power plant operation requires an optimal mapping between unit load demand and pressure set point in a fossil fuel power unit (FFPU). In general, the optimization problem with varying unit load demand cannot be solved using a fixed nonlinear mapping. This paper presents a modern heuristic method, particle swarm optimization (PSO), to… (More)

Coordinated control schemes, at fossil fuel power plants, drive units as a whole through a variable pressure operating policy. Ordinarily, the pressure control loop set-point is obtained from the unit load demand through a fixed nonlinear mapping that does not allow for process optimization under operating conditions different from the originals. This paper… (More)

This paper presents an overall control scheme for wide-range multiobjective-optimal operation of a fossil-fuel power unit. The scheme provides the means to accommodate operating scenarios characterized by multiple operating requirements, and to attain optimal operation along any arbitrary unit load-demand pattern. The proposed strategy builds upon current… (More)

A coordinated-control scheme with a compensator for a fossil-fuel power plant is presented. The compensator is intended to reduce the interaction effects among the control loops to ease control during wide-range normal operating conditions. Placed between the controllers and the power plant, the compensator only introduces compensation factors among the… (More)

This paper presents two realizations a 2-DOF PI fuzzy gain-scheduling controller for widerange speed control of combustion turbogenerators. The 2-DOF scheme allows independent tuning of the reference tracking and the disturbance rejection characteristics for the controlled system. Then, the fuzzy approach extends these characteristics all over the operating… (More)

Abstract: This paper introduces a compensation scheme for power-voltage interaction in a gas turbine driven power plant. The compensation scheme includes two fuzzy systems. The first fuzzy system compensates the effects of a change in voltage set-point over the power control loop. Complementarily, the second fuzzy system diminishes the effects of a change… (More)

Development of control systems for power plants must demonstrate satisfactory real-time performance in both, the development and the target platforms, before going into actual operation. This paper presents the tuning procedure of a four-loop cascaded control scheme for a gas-turbine driven electric generator, and the real-time performance evaluation,… (More)

A gain-scheduling control scheme produces a nonlinear global controller from a series of local controllers tuned at specific operation points. A major problem on the design of gain scheduling controllers is the design and implementation of the switching logic to have a smooth plant response all over the operation range. This point is solved with the… (More)
