The electric power system is an important part of the national economy. Substation, as a core element of the electric power system, has problems such as difficulties to supervise. This paper proposes the use of digital twin technology to solve the problem of regulatory difficulties. Firstly, the mathematical model of substation digital twin is established. Then the digital twin engine is designed based on the model, which realizes real-time orientation of the personnel through UWB location technology, realizes real-time monitoring of personnel, work, equipment operation, and work area through job management, realizes real-time monitoring of production data through equipment data mapping, realizes early warning and rapid emergency response through operation rules. At last, the prototype system is developed to verify the function. The experimental results show that the system can effectively improve the supervision capability of the substation. This solution can provide a useful reference for systems with similar needs.
