Digital Twin System for Transformer Station Based on Cloud-edge Collaboration Architecture

The transformer station is an important link in the transmission process of the power grid, digital twin is a new way to develop intelligent transformer, which can effectively improve the safety of the transformer station. In this paper, the digital twin technology is applied to the transformer station. Firstly, the basic architecture of digital twin is analyzed, two network deployment schemes are proposed according to the requirements of three-dimensional model construction, information transmission, and two-way interaction to provide a stable infrastructure for digital twin. Then, according to the characteristics and needs of the transformer station, a digital twin transformer station is built based on the cloud-edge collaboration architecture, and the capabilities of the cloud and the edge are defined. Finally, a digital twin transformer station model is built from multiple perspectives. An all-weather detection model is proposed for the safety requirements of the transformer station, and the detection content and information interaction are determined.
