摘　　要：针对滑压运行调峰机组燃煤电站锅炉燃烧系统特点，设计一套新颖实用的控制方案。对主压力-燃料量控制回路及带氧量校正的送风控制回路采用二自由度PID算法以兼顾目标跟踪和干扰抑制；对不同负荷所投入的燃烧器火嘴数量进行燃料量调节回路的PID参数自整定以适应不同负荷工况；改变给粉机电机转速和送引风量的调节方式及电源切换方式。According to the features of combustion control system of coal-fired utility boiler, a novel practical control strategy is presented. Both set-point following and disturbance resistance are considered, 2 independent parameters PID algorithm is used for main steam pressure-amount of coal loop and forced draft fan with O2% regulating loop, PID parameters are tuned according to numbers of coal feeder motors at different boiler load. Coal feeder motors and FDF & IDF motors are all changed to VVVVF control.
