摘要
根据河坡电厂过热系统工艺及控制对象的分析 ,设计了设定值可变的串级汽温控制系统 ,该系级兼顾高过壁温与主汽温双重控制的特殊要求 ,经现场投运 ,控制品质优良 ,达到运行要求。
By analziyng the superheat(SH)system and the control object,a casecade control system with changable setpoint is designed,which can meet the special control demand of both SH steam temperature and SH wall temperature.Practical application prooves that the controller has good performance and meets the requirement of operating parameters.
