摘要
介绍了自动发电控制(AGC)的功能以及机组协调控制系统(CCS)的控制方案,提供了韶关市坪石发电厂2×300MW国产循环流化床亚临界机组为提高AGC投运率、优化AGC调节品质而采取的协调控制策略。实际运行表明,机组AGC月投入率达99.3%,调节品质基本满足电网调度要求,提高了机组整体的自动化水平。
The functions of AGC and the control scheme of the unit coordinative control system (CCS) were introduced.The coordinative control strategy,which is adopted in 2×300MW domestic subcritical CFB unit in Shaoguan Pingshi Power Plant for raising the AGC operation rate and optimizing the AGC adjustment quality,was provided.The practical operation shows that the month operation rate of the unit AGC is 99.3%,and the adjustment quality of the AGC can basically satisfy the requirements of the power grid;so the automation level of the whole unit was raised.
