Parameter Optimization Calculation and Realization Method of Cascade Circuit for Superheater Spray Desuperheating

精确计算减温器喷水的主汽温度串级回路的调节器参数,可以使系统获得更快的响应,同时稳定过热蒸汽出口的温度参数。通过优化计算,说明闭环响应速度、工作周期变化的一种趋势,从而找到可能的变化方向,便于精确认识和优化常规的控制策略。

Accurate calculation of the regulator parameters of the main steam temperature cascade circuit of the desuperheater spraying water can make the system respond more quickly and stabilize the temperature parameters of the superheated steam outlet at the same time. By optimizing calculation, a trend of closed-loop response speed and work cycle change was explained to find the possible direction of change, so as to accurately understand and optimize the conventional control strategy.
