摘要
已有监测方法存在通信盲区,采集数据平稳度较差,致使设备故障预测误差率较高,无法满足智能电网发展需求。为此,提出基于改进射频识别(radio frequency identification,RFID)技术的输配电设备全生命周期智能化监测方法。划分输配电设备全生命周期阶段,并总结生命周期阶段判定特征;以此为基础,改进RFID技术搭建多天线RFID通信框架;以搭建通信框架为依据,结合设备不同生命周期阶段特性,自适应调整运行数据的采集间隔,获取输配电设备运行数据;有效结合整合移动平均自回归(autoregressive integrated moving average,ARIMA)模型与支持向量机算法,提前预测输配电设备故障,从而实现输配电设备全生命周期的智能化监测。试验结果表明:所提方法的输配电设备运行数据采集平稳度数值较小,故障预测误差率较低。输配电设备智能化监测结果可以反映智能电网的稳定运行、发展进度与供电质量,以此保障输配电设备的可靠运行。
The existing monitoring methods have communication blind areas and poor data collection stability,resulting in high error rate of equipment fault prediction,which can not meet the development needs of smart grid.Therefore,an intelligent monitoring method for the whole life cycle of power transmission and distribution equipment based on improved radio frequency indentification(RFID)technology was proposed.The overall idea was to divide the whole life cycle stages of transmission and distribution equipment,and summarize the judgment characteristics of life cycle stages;based on this basis,the RFID technology was improved to build a multi-antenna RFID communication framework;based on the construction of the communication framework,combined with the characteristics of different life cycle stages of the equipment,the collection interval of operation data was adjusted adaptively to obtain the operation data of transmission and distribution equipment;autoregressive integrated moving average(ARIMA)model and support vector machine algorithm were combined effectively to predict the failure of power transmission and distribution equipment in advance,so as to realize the intelligent monitoring of the whole life cycle of power transmission and distribution equipment.The test results show that the proposed method has a small value for the smoothness of data collection in the operation of the transmission and distribution equipment,and a low error rate of fault prediction.The intelligent monitoring results of power transmission and distribution equipment can reflect the stable operation,development progress and power supply quality of the smart grid,so as to ensure the reliable operation of power transmission and distribution equipment.
