| 摘 要： | 超临界机组三输入三输出协调控制系统对象结构对变负荷过程中的热量平衡与负荷调节的抗扰动能力提出了更高的要求。文章分析了国电北仑电厂1 000 MW超超临界机组工艺过程,提出了超超临界机组协调控制优化方案;采用了一系列改进措施来改善过程协调性与动态品质,如加快锅炉动态响应的并行前馈控制,在锅炉主控制器中通过变参数控制,对进入给水指令的锅炉主指令进行分解,然后通过反馈信号来校正前馈等,获得了满意的效果。

| Abstract: | The object structure of 3-inputs and 3-outputs for the coordinated control system of ultra supercritical(USC)units calls for a better heat balance during the load changing and a stronger anti-disturbance capability for the load regulation.The paper analyzes adequately the production process of 1 000 MW USC units in Guodian Beilun Power Plant,and puts forward an optimized control strategy for units.The optimized control measures are adopted to improve the process coordination and dynamic quality,including pa... |
