对灰色理论的基本原理进行了简单介绍,同时还介绍了用灰关联理论进行故障诊断的原理、方法及步骤,建立了简单的、适用于泵站机电设备的故障诊断模型.理论分析表明,在数据量不大的情况下,采用灰关联分析法是进行泵站机电设备故障诊断的一个简单有效的工具. The basic principle of gray theory is introduced briefly. At the same time, the principle, method and steps of fault diagnosis with gray relational theory are also introduced, and a simple fault diagnosis model suitable for pumping station mechanical and electrical equipment is established. Theoretical analysis shows that in In the case of small amount of data, the gray relational analysis method is a simple and effective tool for fault diagnosis of mechanical and electrical equipment in pumping station.
