摘　　要：总结了汽轮机回热系统常见故障,建立了回热系统典型故障集。在利用模糊规则建立回热系统故障征兆知识库基础上,提出了一种基于支持向量机多分类算法的回热系统故障诊断方法。最后将该方法用于某汽轮机组回热系统故障诊断中,结果表明,该模型能有效的识别回热系统故障。The faults of regenerative heating system are briefly summarized, the typical fault set of regenerative heating system is built. A fault diagnosis model of regenerative heating system based on multi-class support vector machines algorithm is presented. Finally, the faults in a regenerative heating system of a turbine unit are diagnosed with the aid of the presented method, the result of diagnosis shows that it is simple and practical and it can effectively identify the regenerative heating system faults.
