The Application of Digital Twin Technology in Substation Management

With the development of information technology, the level of intelligence in substations has also improved, and at the same time, faults in substation equipment have also occurred frequently. To prevent power equipment from malfunctioning during operation and affecting the operation of substations, a substation management system based on metaverse digital twin technology is proposed. The system mainly collects data generated during the operation of the substation through the monitoring and protection module, and transmits it to the digital twin module through the communication module in the system. The virtual substation model is generated through mirroring, and the PLC automatic control module is used to control the voltage, reactive power, operation status, etc. of the equipment. The test results show that the system can achieve modeling of substations with single structure, large scale, and complex structure. It can effectively control the voltage and power of equipment in substations, and plays a very important role in improving the operational level of equipment in intelligent substations.
