Design and Cutting Method of Substation Information Model Describing the Primary Equipment and its Connections

Model inconsistency will impede efficient data exchange among different systems. Currently, substations and master stations use different standards to describe the equipment in substations and have established corresponding models respectively. The substation model focuses on logic nodes to describe the equipment data, which is not compatible with the master station model. Therefore, a data point table is necessary to translate the information in different stations. Such a method increases the maintenance cost and reduces the data quality of the communication process. To bypass the communication barriers, this paper established the equipment entity model from the view of the substation primary side, designed the node calling method to achieve the hierarchical management of equipment connections, and proposed the exact and fuzzing match method to achieve efficient model cutting in response to the master station requirements.
