摘　　要：为可靠掌握变电站开关柜的运行状态,保证变电站的稳定运行,该文设计基于无线传感技术的变电站开关柜故障自动化监测系统。传感节点采集开关柜运行数据,组建分层分簇的无线传感网络,结合能量-周期更新机制,采用双簇头的传输方式传输采集的开关柜运行数据,利用概率神经网络实现开关柜故障自动化诊断,输出故障类别结果。测试结果显示,无线传感网络中节点覆盖率以及网络区域连通率均在93.34%以上,各个节点接收功率的热力分布情况均匀,可以实现开关柜故障的频率可视化。To reliably grasp the operation status of the substation switchgear and ensure the stable operation of the substation,a substation switchgear fault automation monitoring system based on wireless sensing technology is designed.Sensor nodes collect operating data of switchgear,construct a layered and clustered wireless sensor network,and combine the energy cycle update mechanism to transmit the collected operating data of switchgear using a dual cluster head transmission method.Probabilistic neural networks are used to achieve automatic diagnosis of switchgear faults and output fault category results.The test results show that the node coverage and network area connectivity in the wireless sensor network are both above 93.34%.The thermal distribution of power received by each node is uniform,which can achieve fault category classification and frequency visualization of switchgear faults.
