Abstract
Digital twin (DT) is a key technology to improve the digital and intelligent level of substation operation and maintenance. In order to accelerate the application of DT in substations, this paper deeply studies the framework structure and key technologies of the substation DT. First, combined with the operational characteristics of substations, a five-dimensional DT model is proposed, which consists of physical entities of substation, digital models of substation, twin service, twin datasets, and the connection among the parts. Secondly, the framework structure for realizing the substation DT is designed, including device layer, perception layer, network layer, platform layer and application layer. Finally, the key technologies of substation DT are analyzed, and three technical aspects are elaborated from the application of 3D digital model fusion, the construction of substation lightweight digital model, and the interaction between data middle platform and application layer based on multi-agent.
Keywords
substation digital twin, five-dimensional model, framework design, multi-agent, lightweight construction method
