Research And Design Of Substation Simulation System Based On Virtual Reality

Aiming at problems existing in current substation training systems,such as weak to fault simulation,the lack of the sensed presence,simple inspection way and the defective of the system function,the research and design of substation simulation system based on virtual reality is proposed.The simulation object is a 110 kV substation.And the perfect interactive functions that Unity3 D offered and the powerful hardware support of HTC vive are used in this system.The main research contents are as follows.(1)Through collecting video and picture material of transformer substation,consult references,the main equipment model and fault model of transformer substation are established by using 3d modeling software.The modeling of equipment is based on polygon modeling.And it also presents the visual effects of fault of substation equipment with particle system.Meanwhile,the equipment information and fault information are stored in the database.(2)The immersive simulation platform is built according to the system simulation.Through the docking of the system software and the hardware equipment,the interactive control program is written to realize the system immersive roaming,immersive device interaction and immersive fault simulation.(3)In order to deepen students' cognition of professional knowledge,video teaching module is introduced into the system design,which can be selected according to the needs of students to play video or 3d animation video.In order to consolidate the basic knowledge system of the students,the system assessment module was developed,the database technology was used as the benchmark,the test information was called,and the system assessment function was realized.The system integrates 3d visualization,fault simulation,immersion teaching,video display and assessment.The system is fully functional,portable,expandable and maintainable.The traditional desktop simulation model of substation is broken,and immersive technology is adopted to bring a real sense of presence,immersion and interest to the students.The fault simulation is added to make up for the lack of simulation system.And the basis for the students' learning effect test is provided by the introducing of the appraisal system,and the improving of the system of evaluation mechanism.
