DEB协调控制系统的稳定性分析

Stability analysis on DEB coordination and control system

分析了单元机组参数随负荷不同而变化的原因 ,以及DEB协调控制系统的设计思想和控制机理 ,指出单元机组的DEB协调控制系统实际上是以参数基本不变的炉膛为控制对象 ,而将参数变化较大的的环节置于闭环之外 ,从而避免了系统在工况变动时 。

This paper analyzes the reason that the unit machine set parameter varies with the different load and the design idea and control mechanism of DEB coordination and control system.And it also poses that this system acctually makes the common unchangable parameter stove chamber the control object,makes the bigger varifying parameter link outside of close round to avoid the effect of varifying parameter to system stability when the working situation varies.
