Synchronous Fault Diagnosis Method for Smart Electricity Meter Communication with Small Signal Stability
To address the low accuracy of fault diagnosis caused by the interference of small signal stability in meter,a communication fault synchronous diagnosis method of intelligent meter considering small signal stability is proposed.According to the structure circuit of RS-485 communication chip in smart meter,the communication process of smart meter is analyzed,the communication fault analysis tree of smart meter is established,the fault communication connection of smart meter is studied in the form of network layer directed graph,the communication fault of smart meter is diagnosed synchronously,the small signals involved in the synchronous diagnosis of communication fault of smart meter are filtered to remove noise,and the synchronous diagnosis results of communication faults of smart meters are optimized.The experimental results show that when the learning rate is certain,the loss value of the design method is lower and the diagnosis accuracy is higher;when the learning rate changes,the diagnostic accuracy of the design method reaches the highest at 0.005,which ensures the synchronization of intelligent meter communication fault diagnosis process,and provides a theoretical reference for the intelligent application of intelligent meter.
