传统楼宇配电设备故障方监测需安装大量温度传感器与通信装置,成本高,计算过程复杂。提出一种新的楼宇配电设备控制回路故障监测方法。通过采集终端、数据传输部分以及监控信息处理部分三个部分实现。采集终端安装在配电设备回路中,利用带通滤波分割重构Hilbert幅值谱,获取原始信号的时频矩阵,采用HHT方法提取回路故障特征,输入多级SVM中进行训练,实现对故障的分类识别。实验结果表明,所提方法监测准确性高。

A large number of temperature sensors and communication devices need to be installed in the fault monitoring of traditional building power distribution equipment,which has high cost and complex calculation process.A new fault monitoring method for control loop of building distribution equipment is proposed.Through the collection terminal,data transmission and monitoring information processing three parts.The acquisition terminal is installed in the circuit of distribution equipment.The Hilbert amplitude spectrum is reconstructed by band-pass filter segmentation,and the time-frequency matrix of the original signal is obtained.The fault feature of the circuit is extracted by HHT method and input into multi-level SVM for training,so as to realize the fault classification and identification.The experimental results show that the proposed method has high monitoring accuracy.
