300MW机组协调控制策略的应用及改进

Application and improvement of coordinated control strategy on 300MW unit

介绍了300 MW机组分散控制系统的协调控制策略。系统设计了多种辅机故障时的负荷限制功能,改进了RB方式下保证燃烧系统稳定的措施,提出了根据前馈的微分作用快速调节燃料量的方法。

Coordinated control strategy of 300MW unit is introduced.it designs kinds of load limit functions responding to subsystem fault,improves measure which ensures burning system steady on RB mode,and describes method of adjusting fuel flow rapidly which based on derivative action of feedforward.
