循环流化床锅炉床温及床压建模
摘要
为了优化循环流化床(CFB)锅炉床温及床压控制
根据对床温、床压与一次风量和回料阀开度关系特性的分析
利用Libsvm软件包建立了基于支持向量机(SVM)算法的CFB锅炉床温及床压模型
并采用Matlab软件和300 MW机组CFB锅炉运行数据对所建模型进行了验证。结果表明
该模型具有较好的准确性以及较强的泛化能力。
Abstract
In order to optimize the bed temperature and pressure control effect for circulating fluidized bed(CFB)boilers
the Libsvm soft package was employed to establish a support vector machine based bed temperature and pressure model
on the basis of analyzing the relationship among the bed temperature/pressure
primary air and fuel valve opening degree.Moreover
this model was verified by Matlab software and field test data of a 300 MW unit CFB boiler.The results show that
this LIBSVM-based algorithm has great accuracy and well generalization ability.
