摘要

对于主蒸汽温度具有大惯性、大延迟、时变性、不确定性和非线性特点的控制对象

采用传统的串级控制方法难以取得良好的控制效果。分析了德国西门子公司的主蒸汽温度控制策略

其通过计算过热器蒸汽焓值确定喷水减温阀出口温度的设定值

主蒸汽温度将随负荷的变化而改变

以适应不同运行工况下过热蒸汽温度动态特性的变化

从而获得良好的控制品质。试验表明

该策略具有较好的鲁棒性和抗干扰性

改善了主蒸汽温度调节的动态特性。

Abstract

The main temperature is a control object with behaviors of large inertia and delay

time variability

uncertainty

and non-linerarity etc.

hence it is difficult to obtain good control effectiveness using general cascade control strategy.The main steam temperature control strategy put forward from Siemens Corporation has been analysed

in which the set value of output temperature for valves used to spary desuperheating water is determined by calculating the steam enthalpy of superheater

the main steam temperature can vary with the load to adapt the variation of dynamic behavior under different operating conditions

and to reach a good control effectiveness.Test shows that the control strategy from Siemens Corporation has good robustness and anti-jamming ability

and the dynamic behavior of main steam temperature regulaton being improved.
