摘要
结合超临界机组的特性及协调控制数学模型,详细分析了某600 MW机组协调控制逻辑。其锅炉主控和汽机主控逻辑均包含具有增益系数的典型加法器。针对以锅炉跟随为基础的协调方式(BFCC),借助机组的全工况仿真系统进行仿真优化试验,以比较不同增益系数下机组负荷及主汽压力的控制效果,确定最优的增益系数。研究结果对深入了解超临界机组的协调控制潜力和提高机组对自动发电控制(AGC)的适应能力,具有一定参考意义。
Combining with the characteristics of the supercritical power unit, and the mathematical model of coordinated control, the coordinated control logics of certain 600 MW supercritical power unit are analyzed in detail. In both boiler master control logic and turbine master control logic, typical adder with gain coefficient is included. In accordance with the boiler following based coordinated control （BFCC） mode, the simulation optimization test is conducted with help of full-scope simulator of the unit. The control effects for unit load and main steam pressure under different gain coefficient are compared, thus the optimal gain coefficient is determined. The results of research possess certain reference significance to understand the potential of coordinated control of supercritical power unit, and improve the adaptability of the unit upon automatic generation control （AGC）.
