Abstract
On the basis of analyzing problems occurred in automatic control logic of feedwater for Huaneng Shidongkou Second Power Plant,relevant control strategy optimizations were conduc-ted,such as regulating the upper limit parameters of flow in feedwater pump,adj usting the lower limit of feedwater control valve,modifying the distribution strategy of two parallel feed-water pumps,and preventing the PID controller of the feed-water system from intergral saturation.Af-ter improvement,the control logic can not only satisfy the control of feedwater during the unit's start-up period,but also realize full-time automatic control of feedwater during start-up,shutdown and running of the unit.关键词
