Moisture regaining feed-forward control method based on supplied material water content differences
InactiveCN103383541AImprove the calming effectShort delayRatio controlAdaptive controlLoop controlClosed loop
The invention discloses a moisture regaining feed-forward control method based on supplied material water content differences. Due to comparison of the differences of smoke block supplied material water content and a preset value, a water supplying coefficient of a loose moisture regaining cylinder is modified, and therefore actual water supply amount is adjusted. The method includes the steps of collecting material water signal w1, comparing the differences between the w1 and a material water content preset value w0, obtaining a water supply coefficient modified value K' through calculation, collecting material flow signal P, obtaining a water supply amount value SP after calculation, and modifying an actual water supply amount value in real time according to the water supply amount value SP through a water flow meter after data stack delay so that the actual water supply amount value is consistent with the water supply amount value SP. Front-period turbulence is taken as a main reason, on the basis of the water content differences between smoke blocks at an inlet, a water supply coefficient K is modified, and the preventing effect of turbulence of the water content at a smoke sheet outlet is good. Data stack delay is short, and the response speed of water supply amount closed-loop control of a loose moisture regaining device is greatly improved.

According to the method, the output fluctuation of the photovoltaic system isstabilized with the combination of the energy storage device, the problem that the capacity design of the energy storage system existing in the current energy storage stabilization technology is too large is solved, the stabilizing effect is improved without affecting the grid connection reliability, and the overall economic performance of the system is improved.
