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.
