The objective of this paper is to present a new simulation code for the steam power plant at both full load and partial loads. The simulation program has been created to model a thermal power plant (i.e. Neka steam power plant 4x440 MW) which has a slide pressure boiler at partial loads. Results of this simulation code are compared with an actual running power plant results. The comparison shows that the modeling resultsagree very well with actual results. At the next part simulation of the power plant has been created considering constant pressure for boiler (i.e. governing via a throttle valve), and performance of the plant has been compared and discussed in two cases
