Problems solved by technology
The biggest disadvantage of the mathematical modeling method is that it is difficult to obtain an accurate mathematical model for complex industrial processes. Generally, only the identification method can be used to obtain an approximate mathematical model, and the obtained mathematical model has a large error
[0007] Limited by factors such as theoretical knowledge and practical experience, when using pattern recognition, rule reasoning and mathematical modeling, it is difficult for on-site measurement personnel to accurately locate the cause of the fault and quickly solve the problem

Description
technical field [0001] The invention mainly relates to the technical field of electric power equipment, in particular to a reliability-based fault analysis method and device for an electric energy metering device. Background technique [0002] As a trade settlement device between power users and power supply companies, once the energy metering device fails, the power supply company needs to investigate and deal with the cause of the failure in the shortest possible time to avoid economic disputes with users. However, with the full application of smart meters and the full coverage of electricity consumption information collection, the appearance and types of problems externalized after the failure of electric energy metering devices are intricate, so higher skill requirements are put forward for the on-site metering personnel of power supply companies. [0003] At present, there are mainly three troubleshooting and diagnosis methods for electric energy metering devices: patte...
