Research and application of substation digital twin technology based on panoramic state monitoring

With the deepening development of smart grid, the intelligent operation and maintenance of substation has become the core demand to improve the reliability and efficiency of the power system. This paper puts forward a digital twin technology framework based on panoramic state monitoring for the problems such as many hidden dangers and lagging fault response in the traditional substation operation and maintenance mode. Through the construction of 3 d digital model, combined with multi-source sensor data collection and intelligent analysis algorithm, the real-time monitoring, fault warning and intelligent maintenance of equipment status are realized. Practical application shows that the technology can significantly improve the efficiency of operation and maintenance, reduce the risk of failure, and provide technical support for the digital transformation of the power system.
