摘要
本文是异步电机在起动—断电—重合闸的瞬态情况下,建立了异步电机在α-β-0静止坐标系下的仿真模型,并分析了重合闸时初相角对冲击电流和电磁转矩的影响。利用MAT-LAB/Simulink中的一些基本模块进行了仿真,并给出了仿真结果。
A mathematical model for induction motor at starting, absence of the su-pply and relcosing are formulated in this paper. The simulation model based on α-β-0 static coordinate is constructed by using the basic components of MATLAB SIMULINK toolboxes. The transient current and electric torque are predict when reclosing with different initial phase angle. The simulated results are also given here.
