锅炉不同动态数学模型的比较

Comparison of Different Boiler Mathematical Models

以带有ＨＧ６７０／１４０５自然循环锅炉的２０万千瓦机组为例，建立了６种不同的数学模型；根据数字计算得出的结果，给出了燃料量改变后６种不同模型所反应的机组主要参量的动态过程，并对其动态过程加以比较，探索这些模型的特色．

Based on six different mathematical models of a 200 MW generating unit with HG 670/140 5 natural circulation boiler, this article gives the dynamic responses of main generating parameters affected by fuel changes according to digital computation. In addition, the dynamic processes are compared to gain the characteristics of these models.
