摘要

本文利用Simulink s函数对电厂过热器进行了动力学和控制仿真。过热器是热交换器，将能量从烟道气转移到过热蒸汽。过热器及其输入、输出管道和配件的组成称为过热器总成。过热器总成的惯量往往是蒸汽温度控制系统设计的决定性因素。用一组非线性偏微分方程描述了过热器总成的数学模型。为了分析数学模型的准确性，用测试信号对系统进行了搅拌。在电厂进行的实验进行了数学模拟。测量数据与仿真结果进行了比较。

Simulation of power plant superheater by Simulink S-functions

The paper deals with simulation of both dynamics and control of power plant superheaters by means of Simulink S-functions. Superheaters are heat exchangers that transfer energy from flue gas to superheated steam. A composition of superheater, its input and output pipelines, and fittings is called a superheater assembly. Inertias of superheater assembly are often decisive for design of a steam temperature control system. Mathematical model of a superheater assemble is described by sets of nonlinear partial differential equations. To analyze accuracy of the mathematical model, the system was agitated by test signals. Experiments carried out at the power plant were simulated mathematically. Data obtained by the measurement was compared with simulation results.
