Dynamic modelling and simulation of power plant systems

This paper gives a brief review of the modelling and simulation techniques and describes basic steady state and dynamic models for power plant components. As an example, a dynamic model for a 677 MW coal- and gas-fired power plant has been built with MATLAB and SIMULINK. Every power plant component was modelled using mainly physical modelling techniques and a whole-plant model can easily be configured by graphically linking the standard components by steam and gas flows, as in physical processes. The simulation results of responses to typical plant disturbances are satisfactory.
