例子是关于单机-无穷大系统三相、单相短路、两相短路和两相短路接地的仿真模型，其中测量和显示模块均设置好了，可以得到各种短路情况下的电路电流波形。-Example is a single machine- infinite bus system, three-phase, single-phase short circuit, two-phase short-circuit and two-phase short-circuit ground simulation model, which measure and display modules are set up, you can get a variety of short-circuit case circuit current waveform.
