摘　　要：火电生产动力用煤品种繁杂,成分区别很大。随着煤质的变化给火电机组AGC控制带来了困难,因此针对煤质问题研究了一种基于CEMS的煤质计算新方法,用于燃料与风量调节的自动校正,使机组具有煤质自适应的AGC功能。Coal-fired power consumed varieties of coal is complex, element is very different. Thermal power units of the AGC control become difficult with the changes of coal quality. Conventional design of coordinated control more difficult to adapt to the changes of coal quality. The issue of coordination control is volatile or unstable and AGC don＇ t work become sedous. A study of new method of calculation based CEMS system to solve this problem, Coal thermal power units with the adaptive AGC function become a reality is based on fuel and air volume adjustment of automatic correction.
