The power grid may have higher requirements on coordinated control system(CCS) of power unit, thus the measures of enhancement of CCS are stated. These include add load demand signal as feedforward signal to boiler main steam pressure control loop; and balance pressure through changing load demand when larger change of main steam pressure occurs. The implementation of these measures will improve the regulating quality of CCS, enhance the adaptive capability to external load change and eliminate the overshoot of main steam pressure.
