电磁场虚拟仿真实验的构建与开发

本项目针对电磁场理论难学、难懂、难用及特高压输电试验成本高的特征,借助虚拟仿真技术,以电力电缆、绝缘子和分裂导线为实验对象,采用需求牵引基于问题的互动式、设计式、探究式等相融合的教学方法,将电磁场静电场的重点知识分解到3个实验项目中。实验数据均来源于实际工程案例。通过自行建立电力电缆、绝缘子和分裂导线模型,并仿真计算,查看电场分布情况,使学生初步认识电力设备绝缘结构的特点,充分理解电磁场理论在实际工程中的应用。最终达到“基本原理学习、综合能力提高、建立工程意识”的教学目标。

Virtual Simulation Experiment of Electric Eield of Typical UHV Transmission Equipment

This project aims at the characteristics of electromagnetic field theory that is difficult to learn, understand, and use, and the cost of UHV transmission test is high. With the help of virtual simulation technology, power cables, insulators and split conductors are used as experimental objects. The author adopts demand-driven, problem-based teaching methods that integrate interaction, design, and inquiry,and decomposes the key knowledge of electromagnetic field and electrostatic field into 3 experimental projects. The experimental data are all derived from actual engineering cases. Students build power cables, insulators, and split conductor models by themselves, and perform simulation calculations to check the electric field distribution, so that students can have a preliminary understanding of the characteristics of the insulation structure of power equipment and fully understand the application of electromagnetic field theory in practical engineering. Finally, the teaching goal of "learning basic principles, improving comprehensive ability, and establishing engineering awareness" is achieved.
