摘要
火电机组实施低氮燃烧器改造后,机组燃烧特性发生较大变化,需要对机组的AGC功能进行优化,满足电网调度对变负荷速率的要求,并在频繁的AGC变负荷工况下减小机组的汽压、汽温的变化幅度。陕西国华锦界能源有限责任公司1号机组低氮燃烧器改造后的AGC策略优化取得了良好的效果,介绍了在国华锦能公司1号几组AGC策略优化的实施情况。
Combustion characteristics of the unit changes greatly after low nOx burner retrofit of coal-fired power unit, AGC function of the unit needs to be optimized. The reguirement of grid dispatching for load change rate can thus be met, and the changing of steam pressure and temperature of the unit can be reduced during freguent load change under AGC. AGC strategy optimization achieves good effect of No.1 unit in Shanxi Guohua Jinjie Energy Co., Ltd. after low nOx burner retrofit. AGC strategy optimization of No. 1 unit in Shanxi Guohua Jinjie Energy Co.,Ltd. is also discussed.
