Construction of the relay protection device model data center

Relay protection systems in the power grid are individually modeling protection devices based on their respective operational requirements. However, this approach leads to issues such as redundant modeling, independent operation of protection systems, data silos, and challenges in interacting with other business systems. To enhance the level of integrated operation and management, as well as the informatization, automation, and interactivity of the power grid dispatching, there is an urgent need to research the construction method of a relay protection device model center. This research aims to integrate and share comprehensive models and data elements of protection devices distributed across different systems, address the problem of independent maintenance of models and parameters in various systems, improve workforce efficiency, and contribute to the development of modern power systems.
