| 摘 要： | 为满足华北电网"两个细则"自动发电量控制(AGC)的要求,以大同第二发电厂三期工程为例,提出了超临界机组的AGC协调优化控制策略。该优化控制策略在汽机主控中加入了微分信号回路,使汽轮机侧能够快速响应负荷的变化;对负荷速率环节进行修正,当负荷与压力的综合工况改变时,提高负荷变化速率;在压力设定中引入了保持策略,避免了压力偏差大时的波动;用水煤比和压力偏差对锅炉主控前馈进行校正,缩短了锅炉侧的响应时间;在给水控制中加入了过热度调节,有利于压力的变化,避免了水量波动。文中对控制策略优化前后的数据进行比较,证明了优化后机组AGC性能指标有较大提高。这表明优化控制提高了超临界机组的AGC协调控制能力,能够适应"两个细则"的要求,可以争取到一定的补偿。
