Research on Intelligent Diagnosis Unit of Substation Equipment Based on Big Data and Internet of Things

变电站是电力系统的核心枢纽,一旦出现设备故障,极有可能导致设备损坏与停电事故,因此,变电设备的故障诊断具有十分重要的意义。基于大数据与物联网的变电设备智能诊断单元,给出了智能诊断单元的结构层次,提出了物联网大数据平台的功能及要求,并在此基础上提出了采用初级诊断算法与高级诊断算法相结合的变电设备故障诊断方法。最后,针对变电设备智能诊断单元开展了现场应用。现场应用案例结果表明,提出的变电设备智能诊断单元能够准确诊断变电设备故障,并能发出故障预警信号,给出运维检修建议。

Substation is the core hub of power system.Once equipment failure occurs,it is very likely to cause equipment damage and power failure.Therefore,fault diagnosis of substation equipment is of great significance.The intelligent diagnosis unit of substation equipment based on big data and Internet of things was studied in this paper.The structure of the intelligent diagnosis unit was presented,the functions and requirements of the big data platform in Internet of things were put forward,and a fault diagnosis method of substation equipment based on the combination of primary diagnosis algorithm and advanced diagnosis algorithm was proposed.Finally,the field application of the intelligent diagnosis unit of substation equipment was carried out.The result of field application showed that the proposed intelligent diagnosis unit for substation equipment can accurately diagnose the fault of substation equipment,and can send out fault warning signal,and give advice for maintenance and overhaul.
