中文摘要:针对数据提取粗糙,导致配电设备监测预警精度差的问题,将便携式智能传感技术中的光纤传感技术应用到配电设备监测及预警中。基于光纤光栅传感原理,解决光纤传感器温度应力交叉敏感问题,应用样本关联系数,粗略提取最初的振动时间段数据,应用支持向量机方法,提取配电设备监测数据细节,架构配电设备预警流程,完成基于便携式智能传感技术的配电设备监测及预警研究。以配电设备的电流波形与电压波形为实验指标,测试结果表明,监测结果与实际的波形相差较小,且添加故障后,震荡幅度较小,在配电设备正常时,完成配电设备监测及预警。

Research on Monitoring and Early Warning of Power Distribution Equipment Based on Portable Intelligent Sensing Technology
Abstract:Aiming at the problem of poor monitoring and early warning accuracy of distribution equipment due to rough data extraction in vibration period, the optical fiber sensing technology in portable intelligent sensing technology is applied to monitoring and early warning of distribution equipment. Based on the fiber Bragg grating sensing principle, solve the cross sensitivity of temperature and stress of optical fiber sensor, roughly extract the initial vibration time period data by using the sample correlation coefficient, extract the monitoring data details of distribution equipment by using the support vector machine method, construct the early warning process of distribution equipment, and complete the monitoring and early warning research of distribution equipment based on portable intelligent sensing technology. Taking the current waveform and voltage waveform of distribution equipment as the experimental indicators, the test results show that the difference between the monitoring results and the actual waveform is small, and the vibration amplitude is small after adding fault. When the distribution equipment is normal, the monitoring and early warning of distribution equipment are completed.
