基于电力物联网的配电设备监测与故障预警研究

Research on power distribution equipment monitoring and fault warning based on power internet of things

根据配电台区的设备组成分析了监测需求,基于物联网技术设计了3层结构的主站系统,利用改进阻性基波电流法分析避雷器泄露电流,根据阻性电流增长情况判断避雷器运行状态。利用油温变化率、异响声波分贝监测变压器状态,经过模拟实验证明监测方法可以准确反映实际情况,为实现配电设备自动化监测以及故障智能诊断提供了技术方案支持。

According to the equipment components of power distribution area,monitor requirements were analyzed,three layer structure was also designed based on the Internet of Things technology of master station system,analysis of the fundamental wave current method with improved resistance arrester leakage current according to the impedance current growth situation judgment arrester running state.Using the oil temperature change rate and abnormal sound wave decibel to monitor the transformer state,the simulation experiment proved that the monitoring method could accurately reflect the actual situation,which provided technical support for automatic monitoring and intelligent fault diagnosis of distribution equipment.
