Virtual reality technology is applied to substation training and a substation training system is established. Based on virtual reality technology, this paper studies the methods of substation electrical equipment operation, maintenance and simulation training. The overall structure of the substation training system is given, and the functions of the substation training system, the system software and hardware environment configuration and the object modeling method are introduced. The research results show that the application of virtual reality technology to construct virtual environment for substation simulation system can greatly improve the realism of substation scene. At the same time, the power system simulation software is connected with the virtual substation to simulate the various operating states of the substation, which brings a technological leap to the substation simulation training work.
