Unified Model of Substation for Dispatching and Centralized Control Applications

The IEC 61850 model has been widely used in substations nowadays, but it is quite different from the IEC 61970 model, and each one has its own emphasis, resulting in the two model systems being unable to communicate with each other. In this paper, a unified model of substation is constructed based on the analysis of various applications. The modeling idea, model architecture and organization are introduced, the entity model and relation model are introduced in detail, and finally the construction and maintenance process of the model are introduced, and the feasibility of the unified model is verified through practical application.
