Most of the world’s electricity production is met by steam turbine systems, in which it is important to optimize both power production with multistage turbine and thermal efficiency to consume the least possible amount of fuel.
The simulator studies the operation of a subcritical base system with overheating of the steam that enters the
turbine, where it generates electric power, and returns to the thermal generator after being condensed and pumped.
To increase the thermal efficiency, numerous technological devices have been added over time, especially with regard to steam generator, which will be analyzed in the simulation.
