Model-based combined cycle power plant load control
A combined cycle power plant has a control system that develops a gas turbine control signal to control the combustion of gas within the gas burner to thereby control the electrical energy produced by the electrical energy generation unit, wherein the control system includes a controller 112, a proc...

| description | A combined cycle power plant has a control system that develops a gas turbine control signal to control the combustion of gas within the gas burner to thereby control the electrical energy produced by the electrical energy generation unit, wherein the control system includes a controller 112, a process model 116, and a controller input signal generation unit, wherein an input of the process model is coupled to an output of the controller to produce a predicted steam turbine output, and the controller input signal generation unit develops a controller input signal for the controller by combining the predicted steam turbine output, a load set point 104, a measured gas turbine output 106 and a measured steam turbine output 108. This control system provides better unit power set-point tracking and disturbance variable rejection for overall more robust control, and thus operates to optimize the gas turbine operation of the combined cycle power plant in a manner that provides cost savings over time. |
