Simulation Research Of Middle Point Temperature Control Of Supercritical Once-through Boiler

The most important systems in the supercritical once-through boiler-conditioning systems are the water-conditioning and fuel-conditioning systems. With the proper coordination of this two-conditioning systems, superheated steam temperature can meet the basic stability. Therefore, the key and the difficulty of supercritical units'automation control is the control of fuel-water ratio, effect of restricting the control of supercritical units in the overall level of control. This article bases on neural network decoupling control study, the amount of fuel and to the water for the coordinated control of the strong coupling of the characteristics of the object will be decoupled algorithm is introduced into the control system design. Design through the design of the simulation study. The results show that the design has a good decoupling effects and control system for regulating the quality is satisfactory.
