Performance Analysis and Simulation Study of Boiler-Turbine Coordinated Control System

The boiler-turbine coordinated system is a very important process of a power generation unit. This paper takes 300MW power plant as the controlled object and conducts simulation study on its different kinds of load control modes under the environment of the MATLAB. The parameters of PID controller are optimized using signal constraint (S-C) module in Simulink toolbox. By analyzing the results of the simulation and comparing both the advantages and disadvantages of them, we can provide references for the choices of load control mode of power unit.
