大型高炉是钢铁制造过程中的重要装备,由于高炉运行过程复杂,干扰因素繁多,经常会有异常炉况发生。为及时监测异常炉况、保证高炉顺行,本文利用高炉运行数据,开发了一种基于MWPCA和高斯混合模型的算法对高炉异常过程进行监测。由于高炉运行数据存在非高斯分布和时变的特点,利用高斯混合模型改进了传统PCA监测模型的T2统计量,使算法可以适应高炉数据的独特分布特征,并加入了滑窗机制,使算法具有实时更新的能力。随后,将算法应用在华南某大型钢铁集团的真实高炉数据上,检测了算法的有效性,并将其与基础算法进行了对比分析,证明了算法在高炉异常监测能力上有所提高。 相似文献

Very often, there are several kinds of different scale structures, such as atomic/molecular microscale, device/boundary mesoscale and working procedure/operation unit macroscale, etc., referred in the operation of a blast furnace system. However, not enough attention has been paid to the multiscale feature of the blast furnace system by traditional analytic methods which are the average ones over a fixed scale. For this reason, the current work performs a multiscale identification and further makes a dynamical analysis on the blast furnace system from the time series sets of two important components in the blast furnace hot metal, i.e., silicon content and sulfur content, collected from a pint‐sized blast furnace. The results render a strong indication of multiscale characteristic and multiple dynamics, i.e., randomicity, chaos, and limit cycle but with different rates of contribution to the whole system, contained in the blast furnace system. Furthermore, compared with the original blast furnace system, every subscale structure has lower complexity. All of these can serve as guidelines to carry out modeling, control and optimization on complex blast furnace system from the viewpoint of multiscale in the future, and may throw more light on understanding and characterizing its complex dynamics. © 2011 American Institute of Chemical Engineers AIChE J, 2011 相似文献

The prediction and control of the inner thermal state of a blast furnace, represented as silicon content in blast furnace hot metal, pose a great challenge because of complex chemical reactions and transfer phenomena taking place in blast furnace ironmaking process. In this article, a chaos‐based iterated multistep predictor is designed for predicting the silicon content in blast furnace hot metal collected from a pint‐sized blast furnace. The reasonable agreement between the predicted values and the observed values indicates that the established high dimensional chaotic predictor can predict the evolvement of silicon series well, which conversely render the strong indication of existing deterministic mechanism ruling the dynamics of complex blast furnace ironmaking process, i.e., a high‐dimensional chaotic system is suitable for representing the blast furnace system. The results may serve as guidelines for characterizing blast furnace ironmaking process, an extremely complex but fascinating field, with chaos in the future investigation. © 2009 American Institute of Chemical Engineers AIChE J, 2009 相似文献
