摘要
本文讨论了一种关于变压器空载合闸和短路的对比教学方式。笔者利用PSCAD/EMTDC软件搭建单相变压器供电仿真模型,将变压器空载合闸和短路的状态分别模拟出来,对其影响因素进行参数设置,最终得到励磁涌流波形图和短路电流波形图。这种将理论计算结合离线仿真的对比教学方式,有利于电气工程专业本科生全方位理解二者,启发思维,达到良好的教学效果。
The paper discusses a contrastive teaching of transformer no-load switching and short-circuit. Based on theory explanation and formula reasoning,a model has been built with PSCAD/EMTDC software to simulate trans-former non-load switching and short-circuit,the parameters of influencing factors are set,and the current waveform figures are saved. This teaching method combines the theory and simulation in helping undergraduates for more comprehensive understanding and an inspired thinking. It might achieve satisfactory teaching effect.
