Although there are many variations in power plant configuration and design, the basic working principle of the FFPPs keeps the same: fossil fuel is combusted, generating high pressure and tem-perature steam, which is then expanded to rotate a tur-bine, and drives the generator to produce electricity.1 For the FFPP, the main task of the control system is to regulate the electrical power output to meet the demand of the grid while maintain-ing the main thermal dynamical variables such as superheater/reheater steam temperature, throttle pres-sure, furnace pressure, drum water level, within given tolerances to keep the power plant operating safely.
