摘要
把感应电机定子侧绕组的每一个并联分支看成是一个支路,转子侧等效为d轴和q轴两个相互垂直的绕组,建立了基于绕组并联支路的感应电机磁链方程和电压方程.根据故障后支路的电压方程和磁链方程得出了各种绕组短路故障的等效模拟电路;对于绕组断线故障,可令该绕组的阻抗为一个相当大的数来模拟,最后用一个45 kW的电机参数进行仿真.
In this paper, by treating the stator side as every parallel stator branch circuits and disposing the rotor side as d and q windings equivalently, the induction motor model based on each parallel stator branch circuit is built. According to the basic electric circuit theory, the simulation method of various winding fault is deduced. This method has the advantages of strong generality and conceptual clearness, which may be used as a powerful tool to analyze the effect of stator winding faults to large induction motor performances for the investigation of new diagnostic and protective method. Finally, the numerical simulation is conducted and the resuits of the phase to earth short are given.
