面向控制的过热蒸汽温度动态特性分析
摘要
由于火电机组热力系统建模及仿真机技术的复杂性
模型本身热力系统动态过程机理模型通常难以直接用于机组控制系统的设计。为此
以超临界600MW机组直流锅炉为研究对象
构建了超临界压力直流锅炉数学模型和基于仿真试验结果的对象传递函数辨识模型
并分析了其合理性
为锅炉控制系统的设计建立了的基础。
Abstract
Because of the complexity in establishing model and emulation technology for the thermodynamic system of thermal power units
a mechanism model for dynamic process of the thermodynamic system is generally difficult to be directly used for designing control system of units.For this
taking once-through boiler of supercritical 600 MW unit as the research object
a mathematical model of supercritical pressure once-through boiler
and a model for identifying the object transfer function based on results of emulation test
have been built
and the reasonableness of them being analysed
laying a foundation for designing control system of boilers.
