Design And Implementation Of Interactive Simulation System For3d Virtual Traction Substation

The traction power supply system is an integral part of the electrified railway,composed of a traction substation and traction network.The two elements complement each other and jointly maintain the catenary network’s power supply and electric locomotive.Traction substation,which connects the power network with the traction network,is an essential part of the power transmission in the traction power supply system and one of the core guarantees of power transmission.This thesis designs and develops a virtual substation interactive simulation training system by combining virtualization technology with traditional teaching.The following aspects are the main research content of this thesis:(1)This thesis designs the three-dimensional virtualized traction substation its functional modules according to the system’s overall hydrangea.It determines the overall technical route of the system realization.At the same time,it studies the technical theory of system realization,determines the system frame structure,and designs the overall completion of the three-dimensional virtualized substation system.Simultaneously,the 3D simulation technology is analyzed,the virtual engine and modeling tools of the system are determined,and design the development process of the simulation system.(2)This thesis selects the data of a traction substation in the west of China,the three-dimensional modeling and rendering of the whole traction substation,including the power equipment,the internal and external environment of the station,the buildings,houses,and roads involved,are carried out by using the modeling software.The problems in the modeling and rendering process are analyzed and expounded.According to different weather conditions,this thesis builds other traction substation scenes,studies and designs the virtual coordinate transformation method and the collision detection method of the 3D model.The above work completed the overall modeling and scene construction.(3)Designing and developing an Android and PC composite system for interactive simulation training of virtualized substations.Designing and developing functional modules such as function modules that can display power equipment information,equipment model search module,and critical power equipment learning according to user needs.Embedded question banks and related power calculations improve the richness of non-interactive operations.(4)Developing and designing the visualized roaming inspection module of the virtual substation.According to the standardized substation tour process analysis,the corresponding programming script is intended to realize the fixed-point tour and complimentary view tour and simulate the substation’s realistic tour operation scenes.Use the digital twin technology to develop the system capable of warning the transformer’s distance and design the main transformer’s digital twin in the substation.The digital twin model incorporates perceivable data and feeds back the system through multiple sources of information.Simultaneously,secondary collision detection is added based on the visual roaming tour to realize the system’s development finally.
