600 MW超临界直流锅炉自动控制系统的特点及控制方案

Characteristics and Schemes of Control System of 600 MW Supercritical Strait Boiler

针对内置式启动控制的600 MW超临界直流锅炉动态特性的复杂性,提出采用前馈、变定值、变参数、变增益、变结构的控制方案,并详细分析了给水控制系统和主汽温控制系统。

Faking the complexes dynamic features of internal seperator start-up systems of 600 MW supercritical pressure boiler, a control design adopts feedforward, varying set point, varying parameter, varying gain and varying structure was bring forward, analyses the feed water control system and the main steam temperature control system detailed.
