<p>In a method and computer program product for optimal operation of a power plant and a power plant optimising system an optimisation module (1) minimises a cost function (JÄuÜ,JÄPÜ) that comprises a deviation of lifetime of plant components (LTp( tau )) from a desired nominal lifetime trajectory (LTn( tau )). This is done by, at a given time, determining future values of input values (u( tau ),P( tau )) such as control values (P( tau )) or process values (u( tau )) to the plant and simulating, in a simulation module (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 (JÄuÜ,JÄPÜ) by varying the input values (u( tau ),P( tau )). As a result, it is possible to operate the plant such that component lifetime (LTp( tau )) follows the desired trajectory (LTn( tau )). <IMAGE></p> |
