利用先验知识和专家经验,在划分机组运行状态的基础上,建立了基于规则的机组安全返回策略,其目的在于当机组能量失衡时,辅助协调控制系统快速将机组主要运行参数拉回正常范围,避免机组解列、跳闸。
According to the Priori knowledge and experts′ experience,a rule-based run back strategy is designed on the division of operation modes of the ultra supercritical units,aiming at assisting the coordinated control system when energy is out of balance and avoiding unit tripping by pulling back the main parameters to normal range.
