Power System Cable Operation and Maintenance Technology Based on OneNET
The present work tries to propose a OneNET-based technology of power system cable operation and mainte-nance,aiming at addressing the high difficulty in power cable maintenance owing to the specificity of power cable deploy-ment.Based on the analysis of the operation configuration and specific cable configuration of the A power system,monito-ring of the cable operation status of the power system is carried out from the perspectives of system planning and deploy-ment,as well as data access and storage,and the temperature,current,and voltage characteristics of the received cable status data are extracted.Using the OneNET platform,a fault diagnosis model based on cable status data is established,which works according to the matching results of the mapping relationship set between cable status data and faults.The application of the proposed technology has been indicated by test results to achieve a fitting error remained lower than 2.0×10-4,with a maximum error of only 1.7749×10-4 and a minimum error of only 1.2626×10-4,during the 30-day operation and management of the A power system cables.
