Three-dimensional visualization of secondary system based on digital twin

Abstract

The digital twin technology has become mature and has entered the stage of popularization and application, but the research on digital twin technology of substation secondary system has not been carried out systematically. This paper provides the idea of digital twin digital analog integration application of secondary system, which realizes the information interconnection of three-dimensional model, loop relationship model and transmission data model. Through the correspondence between physical model such as optical cable and field reality, the physical loop information and corresponding virtual loop information can be viewed more intuitively. Combined with the multi-dimensional data-driven model technology, the correlation information of the secondary physical loop and the logic loop is dynamically displayed in 3D visualization, to provide technical support for the operation and maintenance.
