摘　　要：600MW超临界直流机组协调控制系统以及动态特性都比较复杂。直流炉热惯性小,主汽压作为直流机组控制的桥梁,其控制精度和调节品质直接影响机组安全、经济运行。在方案优化中,充分考虑使用了前馈、变增益、变参数等方案,使机组负荷在快速响应的同时,主汽压力能控制在允许范围内。coordinated control system of 600WM supercritical pressure once-through unit and Dynamic Characteristics are both complicated.Once-through boiler have small Thermal inertia,The live steam pressure control as the bridge of coordinated control system,the control quality and regulation of the accuracy impact on the safety of the unit,and economic operation.In design of this control system,we fully considered the control modes using pre-feed,variable gains and parameters,for controlling the main steam pressure in an allowed range when the unit load is rapidly responsed.
