多参数约束的汽轮发电机组远程振动诊断知识库研究

Multiple Parameter Constraint of Turbo-generator Set Remote Vibration Diagnosis Knowledge Base Research

统计、分析、对比了汽轮发电机组轴系振动信号的处理技术,提出了汽轮发电机组振动故障远程诊断知识库应是多参数约束的建立方法,并阐述了多参数约束的汽轮机发电机组振动知识库的建立及振动特征的对应关系,结合工程实例提出了多参数约束的知识库的建立及对汽轮发电机组振动故障诊断的科学性,为远程诊断知识库的进一步深入研究提供方向。

Statistics, analysis, contrast the shafting vibration signal of turbo-generator set processing technology, puts forward the turbo-generator set vibration fault remote diagnosis knowledge base should be the establishment of the multiple parameter constraint method, and expounds the multiple parameters of steam turbine generator unit vibration characteristics of the corresponding relation and establishment of knowledge base, combining with engineering examples, the establishment of knowledge base and multi-parameter constraint is proposed for vibration fault diagnosis of steam turbine unit is scientific, puts forward the direction of the further study of remote diagnosis knowledge base to provide.
