Optimization of Frequency Modulation Control of Supercritical Reheating Unit

摘要

Through the research on the optimization of FM power plant, main disturbance of the power grid in a side of turbine, the boiler side mainly response delay and inertia and coal quality and for coal and furnace dust, aimed at the problems existing in the traditional PID in the unit control, based on the two degree of freedom PID control unit optimization scheme is put forward. The simulation is carried out before and after optimization, and the stability and economy of power grid frequency have been greatly improved.
