In order to realize shared concurrent personnel training and improve the training efficiency of turbine rotor fault, a hydraulic turbine rotor fault simulation system based on virtual simulation is designed. The foundation layer transmits all relevant data such as the foundation and fault of the turbine rotor to the application layer through the network interface, switch and other equipment. Based on the data, the application layer establishes the three-dimensional modeling of the hydraulic turbine rotor by using VRP modeling control program and 3ds max, and optimizes the model color based on the visual attention mechanism. The details of the hydraulic turbine rotor are displayed through the online simulation module of this layer. After the rotor fault is diagnosed by support vector machine, and the results are transmitted to the management layer. The management can present the fault simulation of hydraulic turbine rotor model through a variety of equipment and complete the virtual scene interaction through VRML interaction mechanism. The test results show that the system has good three-dimensional modeling effect of hydraulic turbine rotor, and the color visual effect of the model is good. Obtaining hydraulic turbine rotor fault diagnosis results can provide reliable support for fault simulation, present accurate fault simulation results to students, and meet the training application needs of multi-personnel sharing and concurrent interaction.
