| 摘 要： | 为克服谐波分析法的近似性,提出利用三相交流电路的波形对称条件,通过坐标变换得到感应电动机的常因数状态方程,根据基于对称因数矩阵的状态方程解析求解方法,确定状态变量的初值,直接求得非正弦变频电源供电时感应电动机传动系统稳态运行的时域解.以方波电压源供电感应电动机传动系统为例,分别进行稳态仿真和动态仿真.仿真结果的对比表明,该方法正确、有效,可为其他电力传动系统的稳态分析提供参考.

| Abstract: | To overcome the approximation of harmonic analysis method,the constant-factor state equation of induction motor is built by coordinate transform using the wave symmetry conditions of three-phase AC circuit.The initial values of the state variables are confirmed according to the analytic method based on the symmetrical-factor matrix,and the time-domain solution to steady-state operation of induction motor drive system of non-sinusoidal variable-frequency power is solved directly.As an example,the steady-state and dynamic process of the induction motor drive system of quadrate-wave voltage source are simulated respectively.The correctness and validity of the proposed method is proved by the comparison of the simulation results,and can provide some references for the steady-state analysis of other electric drive systems. |
