摘要

在超临界600MW机组简化模型的基础上

对现有3种火电机组煤质校正方案进行建模仿真

并将仿真结果与实际曲线进行了对比

分析了各校正方案的优缺点及控制指标

提出了一种煤质自适应校正方案

显著提高了机组协调控制对煤质变化的响应速度和精度

并已应用于多台超临界600MW火电机组。

Abstract

On the basis of simplified model of a supercritical 600 MW unit

simulation on current three coal quality correction schemes was conducted.Moreover

the simulation results were compared with the actual curves to analyze the advantages and disadvantages of each correction scheme and the control indices

thus to propose a coal quality adaptive correction scheme with excellent performance.The new scheme efficiently enhanced the response speed and accuracy of the unit coordinated control system on the coal quality

and has been successfully applied in multiple supercritical 600MW units.
