    2003年DCS改造后，两套锅炉系统底子完结了炉况安稳条件下的自动控制。通过设置适宜的炉排转速、鼓风转速、引风转速限幅值，底子保证了煤的充分燃烧，减少了环境污染。完结了工况安稳时整个锅炉系统的自动控制。一起由于引入燃烧周期的自适应调整‘力Ⅱ快了负荷大幅改动时的响应速度。提高了系统控制的自动化程度。 但在运转期问，发现该锅炉在负荷改动较大的工况下，控制过程中存在以下几个问题：锅炉汽包液位测量存在较大误差;燃烧控制系统无法投自动。 [b]3 问题分析与改进 3.1 汽包液位控制改进[/b] 在锅炉汽包液位测量中，由于汽包液位系统是一个没有自平衡才能的被控方针。当供水量俄然下降或出口蒸汽流量增大时。由于此时锅炉传给汽包的热量不变。致使液体许多汽化。构成汽包液位测量成果偏大;当供水量俄然增大或出口蒸汽流量减小时，情况相反，也就是我们常说的“汽包虚伪液位”.而该锅炉在汽包液位检测回路的原设计方案中忽视了这个问题;直接影响了汽包液位控制的平稳，为此，我们对汽包液位测量成果引入压力补偿，补偿公式如下：

h=[△P+gH(ρ“-ρ)]/[g(ρ”-ρ’)]

式中：h一补偿后的汽包液位;△P-变送器测量的差压值;g-重力;H一汽包高度;ρ-液体参阅密度;ρ‘-水的密度;ρ“-蒸汽密度。汽包压力与ρ’、ρ”之间的联络曲线用折线近似后如表3所示PLV03-0-1 RadiSys。

在HS2000DCS控制点的组态中。运用RPV点中的表达式及折线化算法，很简单完结以上补偿联络。原设计所给出的汽包液位三冲量控制方案如图1所示。PLV03-0-1 RadiSys

通过分析发现，调节器的输人为：汽包液位设定值-汽包液位测量值+主蒸汽流量-给水流量。实践运转中由于各种扰动的影响。给水流域和主蒸汽流量简直不可能相等。该方案的控制成果将使汽包液位发作静差。为此，采用在三冲量基础上的串级控制方案。如图2所示。由于主调节器的效果。该方案较好地了静差PLV03-0-1 RadiSys。
