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。
The coordinated control strategy of 300 MW unit decentralized control system is introduced. The system designed a variety of load-limiting functions in the case of auxiliary faults, improved the stability of the combustion system under the RB mode, and put forward a method of rapidly adjusting the amount of fuel according to the differential action of feedforward.
