摘要
重点分析无线通信技术在变电运维设备故障处理中的应用方案,融合远距离无线电(Long Range Radio,LoRa)、5G、边缘计算以及无线传感网等技术,实现变电设备从数据采集、传输到故障诊断的全流程自动化.通过在某变电站的应用试验,验证了方案的可行性,故障预警准确率高达 95.2%,定位误差仅为 10.5 cm,平均处理时长缩短至18 min,大幅提高了故障诊断与处理效率.
Abstract
The application scheme of wireless communication technology in fault handling of substation operation and maintenance equipment is emphatically analyzed,and technologies such as Long Range Radio(LoRa),5G,edge computing and wireless sensor network are integrated to realize the automation of the whole process of substation equipment from data collection and transmission to fault diagnosis.Through the application test in a substation,the feasibility of the scheme is verified.The accuracy of fault early warning is as high as 95.2%,the positioning error is only 10.5 cm,and the average processing time is shortened to 18 min,which greatly improves the efficiency of fault diagnosis and processing.
