Abstract:
A simulation study of the main steam (steam inlet to the turbine) temperature control system shows that this control strategy is effective. Using microcontroller which is programmed using the PROTUS.
Simulation program to control temperature of the main steam, the microcontroller compare the actual temperature value with set point temperature value, if the temperature is high microcontroller send command to the control valve which will open with certain percentage according to the difference between two temperature and the spray water starting blowdown through the nozzle to cool down the temperature of the steam .
