In order to stabilize the voltage,power loss flow and reduce the probability of safety accidents,the abnormal automatic monitor-ing method based on PLC(Programmable Logic Controller)and 5G technology is proposed.It uses 5G technology Internet of Things tracking technology to collect power user load data,extracts abnormal current features based on load curve,applies PLC technology to analyze the influence of three-phase electricity imbalance,calculates actual power,phase voltage and phase current,evaluates local reference power,automatically drives abnormal current metering equipment to perform monitoring tasks,com-pletes automatic monitoring of current metering equipment.The example test results prove that the voltage limit,voltage phase loss,power loss current and the manual monitoring results of the proposed method are high,and the accuracy of automatic moni-toring is guaranteed.
