|
摘要
在计算机、多媒体影响传统理论教学方式和教育手段的同时,实验教学作为理论教学的延伸和理论联系实际的重要环节,在创新型人才培养、教育教学质量提高方面充当重要角色。当今时代,信息化、网络化飞速发展,虚拟仿真实验优势明显,必然成为传统物理实体实验的有力补充。本文借助MATLAB软件强大的仿真功能,以电流互感器结构理论为基础,重点介绍基于Simulink系统电流互感器模型的构建过程及参数设置的要点。然后利用该模型,进行负载对电流互感器传导精度的影响、一次侧过电流及饱和特性对电流互感器传输特性的影响等4项仿真实验。通过模型建立、参数选择、实验设计及仿真结果的深入分析,仿真实验的灵活性以及在培养学生创新能力方面的优越性得到充分的展现。
While computer and multimedia affect the traditional teaching methods and means of education,experiment teaching as the link between theory and practice plays a significant role in the cultivation of innovative talents and the improvement of the education quality.With the rapid development of information and internet,virtual simulation experiments have obvious advantages and will inevitably become a strong complement to traditional entity experiments.Thus,based on the structure principle of current transformer and powerful simulation function of MATLAB,the construction of current transformer model and parameter setting are emphatically introduced in this paper.Then the four simulation experiments of the application performance of the current transformer are carried out using the model,such as the influence of primary side overcurrent and saturation characteristics on transmission characteristics of current transformer.From building the model,the setting of the parameters to the analysis of the simulation results,the flexibility of the simulation experiment and the superiority in cultivating the students'innovation ability are showed.
