Abstract
Schematic diagram to illustrate the separation and identification of nonlinear flow characteristics for the proposed method. Due to a fact that steam turbines and generators have different dynamic characteristics at different operating points, the static nonlinear flow characteristic (e.g., yellow solid lines in (a)) is overwhelmed by input and output data with dynamic characteristics, such as the blue dots in (a) and their corresponding time series are shown in (b). The key to identifying the nonlinear flow characteristic is to separate it from the linear dynamic submodels at different operating points. The separation is achieved based on some special segments, such as the steady-state segments with constant amplitudes (e.g., red solid lines in (c)), and the slope response segments with large amplitude changes (e.g., green dash lines in (c)).
上传的数据集文件包括一个m文件和一个mat文件,它们的文件名分别为“main_code”和“Figure_data”。
m文件可以用Matlab软件打开和运行。将m文件加载到mat文件中,并且可以自动绘制一些图形以在链接的论文中显示工业案例研究的结果。
