摘　　要：介绍了感应电机模型在EMTP(Electromagnetic Transient Program)中的实现方法及转子断条故障的模拟方法.对转子不同根数的断条故障进行了仿真,分析了转子电流及定子电流边频分量的变化规律.得出了如下结论:转子导条断裂后,转子导条电流增大;断条数越多,转子导条电流增大越明显;离故障位置越近的导条,电流增大越大,越远的增大越小.定子电流中的边频分量随着断条数的增加而增加,但断条数增加到一定数量,反而减小.The implementation of induction motor model in EMTP and the broken bar simulation method is introduced in this paper. Then the variations of rotor bar currents and the （1 - 2s ）f1 component of stator current under different number broken bars are studied. Some conclusions drawn are as follows： After the broken bars, the rotor bar currents become bigger; the more serious the fault the bigger the bar currents change; the colser the relative position to the fault position, the bigger the bar current increases. The （1 -2s）f1 component of stator current increases when the number of continuously broken bars increase; but, when the number of broken bars exceeds a certain number, the （1 -2s ）f1 component will decrease with the increase of broken bars.
