Research and Development of a Mathematical Model for the Surface Heater of a Large-sized Thermal Power Plant

利用STAR - 90仿真支撑系统为平台 ,开发了一套较为精确的数学模型来研究回热加热系统。该模型不仅能够满足一定的静态精度 ,准确地反映和再现实际回热加热系统运行过程各种工况的主要特征 。

With a simulation supporting system STAR-90 serving as a platform developed is a fairly accurate mathematical model to study a regenerative heating system. The model is capable of not only meeting a given static precision, but also accurately reflecting and reproducing the major features of various operating conditions of a specific regenerative heating system. Furthermore, it is also feasible to employ the above mathematical model for the research of certain dynamic characteristics of heaters.
