超临界机组干湿态自动转换控制方法
|
摘要
针对常规的给水控制策略无法使干湿态转换自动进行,易发生干湿态频繁切换、转态时间长等问题,设计了一套超临界机组干湿态自动转换控制策略,既能实现干湿态转换的全程自动控制,降低运行人员的操作强度;又能提高机组的自动控制水平,使机组快速穿过干湿态转换这一主参数不稳定区域,进而提高机组的安全运行水平。
Aiming at the problem that the conventional feed water control strategy can not make the dry and wet state conversion automatically, it is prone to the frequent switching of dry and wet state and long transition time, which will be prone to the frequent transformation of wet-dry state and the long transition time, a set of automatic control strategy for wet-dry state transfer of supercritical unit is designed, which can not only realize the whole process automatic control of wet-dry state transfer, but also reduce the operation intensity, but also can improve the level of automatic control of thermal power units, which can make the thermal power unit pass through the unstable region of main parameters of wet-dry transfer process, and improve the safe operation level of thermal power units.
