3.3.2模拟量控制系统（MCS）：在本系统中共设计了40多套自动调节系统，包括锅炉与汽机的所有重要参数的调节。如机炉协调控制系统（采用直接能量平衡的控制策略）、汽包水位调节、主汽压力调节、主汽温度调节、炉膛负压调节等。以下为汽包水位控制系统实例：
汽包水位是控制系统中最重要的控制指标。汽包水位过高将影响蒸汽质量，水位过低则引起锅炉干烧，造成水冷壁爆裂。在本方案中采用以汽包水位、给水流量和蒸汽流量构成三冲量控制系统与以汽包水位进行单冲量调节结合的控制方案，两种方案在不同负荷阶可手动自动无扰切换。汽包水位作为主调节器的输入，主调节器的输出作为副调节器的给定，与给水流量相平衡。通过调节主给水阀改变给水流量来维持汽包水位的恒定。把主蒸汽流量作为系统的前馈信号，反映和克服系统的外扰，给水流量信号反映和克服内扰。
3.3.3锅炉顺序控制（SCS）
顺序控制系统主要完成各辅机的顺序启停及联锁保护。在顺控逻辑中，采用了分级式结构，功能细化到单台设备控制。通过联锁、保护和安全跳闸功能保证余热锅炉的安全运行。锅炉顺控逻辑主要包括：锅炉启动、锅炉停车、床温高联锁停炉、给水泵与供浆泵跳闸联锁停炉、除灰顺序控制以及送引风跳闸联锁逻辑等。
