基于汽温特性的火电机组过热蒸汽温度控制优化研究
摘要
以某台330MW机组锅炉过热蒸汽温度为研究对象
在分析过热蒸汽温度特性的基础上
构建了以机组负荷为变量的前馈动态补偿函数
并采用Matlab软件对该函数进行了仿真验证。结果表明
以负荷为变量的前馈动态补偿函数较静态补偿函数超调量更小
调节时间短
具有较好的稳定性
可提高过热蒸汽温度的控制品质。
Abstract
Taking the temperature of superheated steam in boiler of a 330MW unit as the object
the feedforward dynamic compensation function considering load as the variable was constructed
based on the analysis of temperature characteristics of the superheated steam.Moreover
simulation verification of the function mentioned above was conducted by Matlab soft.Results show that
compared with static compensation function
the feedforward dynamic compensation function has smaller overshoot
shorter regulating time
and better stability.It can improve the quality of temperature control for superheated steam.
