Improvement of Boiler Feed Water Control Strategy in Coal mine Owned Power Plant

In this paper,combined with analysis on disturbance factors of boiler feed water system of A coal mine power plant,based on the traditional three-impulse control strategy of feed water control,a new strategy is proposed which considers drum pressure differential hysterics signal as the inner feed-forward tracking vice ring,and delays water supply instruction.Practices proves that the control strategy has strong anti-disturbance ability by combustion disturbances,evaporation disturbance test
