继电保护装置：atmega128与cpld合成结构：ad转换器对模拟电流采样，读到的数据存在ram中，并进行fft计算与参考值对比，发出出口信息，完成电动机综合保护，还能提供转子笼条断条的故障-Protection devices: atmega128 and cpld Composite Structure: ad converter for analog current sampling, read data exists in ram, and make fft calculation c

simulink下的异步交流异步电机dqo模型，可以模拟异步电机定子短路和转子断条的故障-asynchronous AC induction motor dqo under simulink model can simulate asynchronous motor stator and rotor off of a short circuit fault

采用MAXWELL/ANSYS的异步电动机转子断条故障的模拟，可直接运行(The rotor broken bar fault of asynchronous motor with MAXWELL/ANSYS can be simulated directly, and it can run directly)
