摘要
Abstract
In the traditional runback(RB)control logic,the rate of pressure reduction is fixed,and the high-pressure regulating valves are closed according to the fixed pressure reduction curve,which cannot take into account the changes in main steam temperature and feed water flow.After the RB control optimization,the pressure reduction rate is dynamically and nonlinearly corrected by using the main steam temperature and feed water flow.The variations in the main steam temperature and feed water flow rate are actively guided by the high-pressure regulating valve to prevent them from exceeding the limit and improve the success rate of RB.关键词
