【摘要】 缺相故障是三相感应电动机的典型故障之一。本文采用三相感应电动机在αβ0坐标系下的数学模型,根据具体故障情况下定子绕组的接线,推导出电机定子端电压的约束条件。编写了一个适合于感应电动机对称和定子不对称运行情况的实用仿真计算程序。通过对定子三角形接法的三相感应电动机的两种故障状态,即电源一相断开和定子绕组一相开路的运行过程进行仿真计算,并对仿真结果进行分析,得出了一些有用的结论。更多还原

【Abstract】 Stator phase failure is one typical fault of a three-phase induction motor. According to the mathematical model of the 3-phase induction motor in αβ0 coordinates, with stator voltage constraints of symmetrical and asymmetrical conditions, the simulation program is applied to two kinds of stator faults: stator delta connection with one-line disconnected and one phase open-circiuted. Through an example, the results are analyzed.更多还原
