【摘要】 针对300MW及以上容量的大型火力发电机组凝结器和除氧器水位受控对象的特点,分析现有控制系统的不足,采用了除氧器和凝汽器水位耦合受控对象的多变量分程协调控制系统.经多台机组实际运行表明,该控制系统结构合理,控制器参数易于整定,具有较强的自适应能力,控制品质优良.更多还原

【Abstract】 Because of the controlled water objects with strong coupling property and the insufficiency of the ex- isting control system,it has adopted that the subsection coordination control system for the water coupling ob- jects of the steam condenser and the deaerator.The test result of practical industrial process of many units has proved its effectiveness and its excellent performance,and stronger adaptive capability than the old control plan.更多还原
