Metadata modeling and management for power communication network operation and maintenance

With the rapid development of the smart grid, the network scale and structure of the power grid are becoming larger and more complex, and the corresponding power communication network operation and maintenance management has put forward higher requirements. At present, the power communication network operation and maintenance data face the following two major problems: the metadata model is not unified, and there is a lack of management tools for the operation and maintenance metadata. Aiming at these problems, this paper establishes a unified power communication network operation and maintenance meta-model, and designs a power communication network operation and maintenance metadata management system based on this, which realizes the automatic acquisition of metadata and the analysis of blood relationship information. The work of this paper not only provides a unified information model specification for the management of the metadata of the power communication network operation and maintenance, which facilitates the storage and interaction of the metadata, but also provides a useful technical reference for the management of the metadata of the power communication network operation and maintenance.
