Abstract:
This paper presents the mathematical modeling of the steam turbine unit
with the fuzzy controller in an isolated operating condition, especially in
nuclear power plants. The water level in the steam generator is one of the
main causes for the shutdown of the reactor. This problem has been of
immense concern during the past years as the steam generator and
governor speed control is a highly nonlinear system showing inverse
response dynamics. In the present research a simulink model of turbine
with fuzzy controller is designed. The results are compared and analyzed
with MRAC design technique to determine better methodological solution
for the steam turbine speed control and achieved, time to the adaption
effectiveness of 0.3 to 2.5% with and without GDB. Improved set point
tracking and control with respect to turbine speed are demonstrated for the
cases when governor dead-band is present and absent.
