Abstract:Aiming at the multi-end maintenance of the relay protection equipment and the inconsistency between the information and the site, the patrol record is cumbersome and error-prone, the manual setting check workload is large and the core is easy to leak, the intelligent substation fiber loop and the signal can not be visualized and displayed. This paper builds a relay protection mobile operation and maintenance system based on multi-dimensional business data fusion, and integrates with the statistical analysis system to realize single-ended maintenance of the account data and multi-system sharing. It integrates with the state maintenance system to realize the standardization of inspection content and intelligent report processing. Integrate with the online monitoring system of the secondary equipment and the OMS fixed value setting system to realize the intelligentization of the fixed value check and improve the check efficiency; and integrate with the SCD control system to realize the visual display of the virtual circuit virtual circuit, virtual terminal and loop relationship of the intelligent device. Through the above analysis, the system realizes automatic collection, intelligent sorting, interactive integration and network sharing of substation relay protection information, and effectively improves the operation level and management of relay protection equipment and secondary circuit on-site operation and maintenance while reducing operation and maintenance costs.
