汽机岛DEH系统APS启动和停止
1.DEH系统APS启动
DEH系统启动在中电江门电厂APS控制中设计的是一键启动模式,无需对DEH系统进行特别操作,即自动挂闸、自动冲转、自动投入同期、并网、自动带负荷。启动过程分为3个阶段:汽机挂闸、汽机冲转、机组并网。
1.1汽机挂闸
当机组满足冲转条件时,DEH系统接收到机组APS启动信号后,将对ETS系统进行首出复位,对机组自动挂闸。挂闸后主汽门全开,联通阀全开。
1.2汽机冲转
机组挂闸后DEH系统自动投入ATC方式,并根据当前的调节级内上缸壁温判断当前启动方式:冷态、热态、极热态。
冷态启动时机组冲转分一下几个阶段:HONEYWELL CC-MCAR01集成系统模块

systems [62], and the extended circle criterion can be used to derive sufficient conditions for the stability of a class of simple fuzzy PI control systems [63]. Due to the strict requirements of circle criterion, Furutani proposed a moving Popov criterion to analyze the stability of fuzzy control system. When the parameters in this criterion θ When set to zero, the criterion is consistent with the circle criterion [64].
4.7 other methods
Robust control techniques (such as vector stabilization, H ∞ control theory and linear matrix inequality) are used to derive TS fuzzy control systems with uncertainty [46]. In addition, the concept of generalized energy [65], the concept of cell mapping [66], the geometric state space method [67], the Hurwitz stability condition method [68], the absolute stability criterion method [69], the method based on kudrewicz theory [70] and the extended Haddad method [71] have been used to analyze the
