Research and Implementation of Rules Extraction Technology for Digital Twin Objects in Distribution Network Based on Semantic Understanding

The digital twin of electric topology grid refers to the digital twin of topology grid, mapping the real world topology grid into a virtual digital space, and then fully reflecting the dynamic changes of entities and their relationships in the whole life cycle time scale through full coverage of high-density dynamic data, so as to achieve intelligent analysis, dynamic decision-making and mutual inductance cooperation based on the full model data of digital twin. The digital topology grid can affect the twin interaction of real reality and digital reality by constructing the closed loop data flow of the electric topology grid. The digitization electric network constructed by it relies on the efficient real-time data flow to realize the situation awareness, virtual deduction, and operation management regulation of the electric grid. Digital twin grid is an inevitable stage for the transformation of fresh forms of electric energy, for example, the smart electric grid, energy Internet of Things, active topology grid, etc., in recent years, and is also an effective test method for new digital infrastructure tasks of electric power from 2020. From the perspective of topology grid digital twin object rules, this paper uses a semantic understanding method to extract topology grid digital object rules, to meet the needs of topology grid digital technology, and promote the business appliance of topology grid digital technology.
