新型的水煤比控制策略分析及应用

Analysis and Application of the New Fuel Follow Water Control Strategy

分析了煤跟水控制策略保持物质平衡的特性,能从本质上解除能量(燃料)和物质(给水)的双向耦合作用,介绍了新型的煤跟水控制策略兼顾汽温、汽压的调节特性,并通过在某超临界直流炉水煤比控制系统成功应用案例,说明了该控制策略的先进性及在超临界机组控制的广泛应用前景。

This paper analyzes on the characteristics of the coal water control strategy to maintain the material balance,which can essentially remove the two-way coupling effect of energy(fuel)and material(feedwater),introduces the regulation characteristics of the new coal water control strategy that takes into account the steam temperature and steam pressure,and through a successful application case in a supercritical once through boiler water coal ratio control system,illustrates the progressiveness nature of the control strategy and its wide application prospect in the control of supercritical units.
