Because the traditional power grid security accident simulation system has the defect of low simulation accuracy,it can not meet the needs of the current power grid.Therefore,the design and research of power grid security accident simulation system based on virtual reality technology is proposed.System software design is the core part,so the software part is mainly designed.The power grid model,transmission line model and other component models are constructed by means of component mechanism and hybrid modeling set.The simulation of power grid,transmission line and components is realized to prepare for the simulation of security incidents.The virtual reality technology is introduced into the model,and symmetrical and asymmetrical security accidents are simulated with various models.The simulation of power grid security accidents is completed and the system design is realized.The accuracy of the simulation system is tested through experiments.The results show that the simulation accuracy of the system is 25% higher than that of the traditional simulation,which shows that the system is highly effective.
