摘要： In a method and computer program product for optimizing power plant control values and a power plant optimizing system an optimization module (1) minimizes total plant operation costs while achieving predetermined required output values for produced power and process steam. This is done by, at a given time, determining future values of control values and simulating, in a simulation module (2), the behavior of the plant up to a given future time. Corresponding fuel costs and generated power are determined in the simulation, and incorporated in an objective function. The optimization module (1) minimizes the objective function by varying the control values. According to the invention, a rate of ageing of plant components is determined when simulating the future behavior of the plant, and the objective function to be minimized comprises said rate of ageing.

摘要： In a method and computer program product for optimal operation of a power plant and a power plant optimising system an optimisation mode (1) minimises a cost function (J[u],J[P]) that comprises a deviation of lifetime of plant components (LTp(τ)) from a desired nominal lifetime trajectory (LTn(τ)). This is done by, at a given time, determining future values of input values (u(τ),P(τ)) such as control values (P(τ)) or process values (u(τ)) to the plant and simulating, in a simulation modulate (2), the behaviour of the plant up to a given future time. Corresponding lifetime values are determined in the simulation, and incorporated in an objective function. The optimisation module (1) minimises the cost function (J[u],J[P]) by varying the input values (u(τ),P(τ)). As a result, it is possible to operate the plant such that component lifetime (LTp(τ)) follows the desired trajectory (LTn(τ)).

摘要： A control system for controlling an industrial process includes an indicator generator configured to determine at least one fuzzy logic based indicator from measured process variables. The control system also includes a state estimator configured to determine estimated physical process states based on the fuzzy indicator. For controlling the industrial process, the process controller is configured to calculate manipulated variables based on (i) defined set-points and (ii) a physical model of the process using the estimated physical process states. Combining a fuzzy logic indicator with a model based process controller provides robust indicators of the process states for controlling an industrial process in a real plant situation in which measured process variables may possibly contradict each other.
