| 摘 要： | 针对循环流化床锅炉发生床料翻床事故的原因及常规翻床处理方法的不足,提出模糊—专家控制策略,即通过控制一次风支管风门和利用一次风机液力耦合器调节两侧床层风压,实现两侧床料的平衡。当被调量偏差的绝对值超出阀值则系统启动基于规则的专家控制功能;当偏差的绝对值小于阀值时,系统将退出专家控制而激活模糊控制功能。控制策略在300 MW循环流化床机组上应用之后,有效避免了翻床事故的发生。

| Abstract: | Owing to cause of bed overturn accident with bed material in circulating fluidized bed（CFB） boiler and deficiency on common treatment to routine bed overturn,fuzzy-experts control strategy has been put forward,that is,balancing bed materials of two sides can be realized by controlling primary air manifold branch gate and adjusting bed pressure of two sides,by using hydrodynamic coupling for primary air.When absolute value of adjusting volume deviation exceeds valve value,system startup will be on rules of expert control;when absolute value of adjusting volume deviation less than valve value,system will withdraw expert control,and activate fuzzy control.After application of control strategy in 300 MW circulating fluidized bed（CFB） boiler,bed overturn accident has effectively avoided. |
