COMPUTER AIDED MODELLING OF LARGE POWER PLANTS

Abstract In spite of their global complexity, power plant processes are essentially modular, in that they are composed by many elements of very few types. This fact has been exploited in conceiving and developing a computer package for computer aided modelling of power plants, which is presently being applied to fossil fired and nuclear units. This work describe the application of the package to a 320 HW fossil fired units equipped with a once-through boiler. In particular there are described the basic principle adopted for definition and modelling of the power plant elementary components. The results got in simulation are compared with real plant data both concerning transient conditions induced by perturbation of the main input variable and steady state computations for different plant loads.
