摘要: For the participation of steam power plants in regulating network frequency, boilers and turbines should be co-ordinately controlled addition to base load productions. Lack coordinated control over boiler–turbine may lead instability; oscillation producing boiler parameters; reduction reliability unit; inflicting thermodynamic tension on devices. This paper proposes a multivariable system based improved sliding mode controller (ISMC). The controls two main parameters i.e., turbine revolution superheated pressure output. this purpose, comprehensive model including complete exact description subsystems is extracted. are determined according our case study that 320 MW unit Islam-Abad plant Isfahan/Iran. ISMC method simulated its performance compared with related real PI (proportional-integral) controllers which have been used unit. simulation results show capability proposed controlling local frequency presence variations disturbances boiler.
