摘　　要：以1000 MW超超临界机组风烟系统为例,介绍了整机自启停系统(APS)机组风烟系统全程自动控制策略设计。实际顺序控制功能采用分级控制结构,分为设备级、单元级和功能组级,论述了各级的顺控功能。全程控制策略对于顺序控制与过程控制针对不同的控制变量采用不同的控制方式,过程量调节系统除有手动调节外,还设计了自动备用状态和自动调节状态。系统投运效果证明了控制策略的有效性和合理性。With the air and flue gas system of 1000 MW ultra supercritical power unit as an example,the complete automatic control strategy for the air and flue gas system of APS（Automatic Plant start-up and shut-down System） unit is introduced.The hierarchical sequential control is discussed,including device layer,element layer and functional group layer.Different control modes are designed for different control variables in both process control and sequential control.The regulation system of process variables has the manual,auto-standby and automatic modes.Its rationality and validity are verified by operational effect.
