基于物联网的分布式电动机故障诊断与保护系统研究
Research of distributed fault diagnosis and protection system of motor based on Internet of Things
摘要
Abstract
In view of problems that traditional motor protection device cannot realize early fault diagnosis and does not have networking function,the paper proposed a design scheme of distributed fault diagnosis and protection system of motor based on Internet of Things and support vector machine algorithm.Lower computer of the system uses symmetrical component method to decompose stator current of motor,judges fault type according to current component value to realize site protection of motor,and sends current data to embedded gateway by ZigBee technology,uploads it to upper computer through GPRS network.The upper computer extracts fault feature vector by wavelet packet decomposition,uses support vector machine to classify motor fault,so as to realize early fault diagnosis and prediction.The actual running results show that the system can diagnose motor fault accurately and implement comprehensive protection effectively.关键词
