Research On Condition Monitoring Of Electric Energy Metering Device Based On Information Fusion Technology

The work of electric energy measurement is a very important work of the electric power enterprise,and it is also the key to establish the trust relationship between the power enterprises and the users.The rapid development of electricity m arket requires that the management level of electric energy measurement must be improved,and the accuracy and reliability of measurement must be ensured.All of which must rely on the progress and development of science and technology.Based on the measurement automation system of Guangzhou Power Bureau and the electric energy metering device management as the research object,introduces the basic structure of the electric energy metering device,aiming at the electrical energy metering device in all possible operation,a detailed analysis of application of monitoring technology in power principle,technology and realization method of metering device running status evaluation.By comparing the background and significance of the state monitoring technology of electric energy metering device and the research trend at home and abroad,the state monitoring technology of the current energy metering device and the technical problems to be improved are sorted out.At the same time,combined with the structure of measurement automation system in Guangzhou Power Supply Bureau,based on the data collected at present,we select and analyze useful monitoring data.The focus of this paper is to combine the information fusion technology with the state monitoring of the electric energy metering device.The use of information fusion technology combined with fuzzy analysis method for data processing,signal measurement automation system collected,establish the monitoring parameters of all kinds of signals of the electric energy metering device state monitoring based on fuzzy relation matrix,the electric energy metering device status on-line monitoring and anomaly judgment.After the completion of the theoretical analysis,the actual case verification is carried out to ensure the feasibility of the research results.
