Design of Virtual Simulation Experiment for Harmonic Detection and Control of Electrified Railway

电气化铁路是电网典型谐波源,是电气信息类专业教学的典型案例,其检测与控制实验涉及电压等级高、安全风险大、动态谐波真实复现困难,传统实验教学模式下难以实现线下操作。据此,基于团队最新科研成果,利用智能信息处理、3D仿真建模、网络通信控制等现代技术,构建谐波知识学习、检测、控制3大实验模块共14个实验步骤,开发高仿真三维场景的电气化铁路谐波检测与控制虚拟仿真平台。学生通过虚拟三维场景,可获得对各种设备、牵引变电所和电力机车运行场景的全方位工程认知,自主选择参数、设备、器件设计实验方案,身临其境地开展谐波检测与谐波控制实验,“现场”观测实验效果。

Electrified railway is a typical harmonic source of power grid,and it is a typical case of electrical information specialty teaching.Its detection and control experiment involves high voltage level,high safety risk,and it is difficult to reproduce dynamic harmonics.The traditional experimental teaching mode cannot be realized.Accordingly,based on the latest scientific research achievements of the team,using modern technologies such as intelligent information processing,3D simulation modeling and network communication control,the harmonic knowledge learning,harmonic detection and harmonic control experimental modules with 14 experimental steps are constructed,and the virtual simulation experimental platform for harmonic detection and control of electrified railway with high simulation 3D scene is developed.Through the virtual three-dimensional scene,students can obtain all-round engineering cognition of various equipment,traction substation and electric locomotive operation scenes,independently select parameters,equipment and devices,design experimental schemes,and personally carry out harmonic detection and control experiments,and“on-site”observation experimental results.
