Digital Twin Coal Mine Underground Substation Based on VR Technology

The operation environment of coal mine underground substation is complex, difficult to monitor in realtime, and cannot cope with all types of faults. To reduce the underground electrical safety accidents caused by irregular operations, this paper proposed digital twin coal mine underground substation based on VR (virtual reality) technology. Firstly, the digital twin coal mine underground substation based on VR technology is designed by considering the operational data, electrical characteristics, and operation procedures of the coal mine underground substation. Then, the mapping of the coal mine underground substation in the virtual space was established to digitally express the physical model of the substation and the equipment operation logic in the virtual scene. Finally, relying on VR technology, the interaction capability between the system and the user is improved, and several functions such as roaming inspection, data analysis, and analog diagnosis in the substation are realized. The digital twin coal mine underground substation based on VR technology has the advantages of digitalization, intelligence, and efficiency, which provides a new idea for the operation and maintenance of the coal mine power supply system.
