摘　　要：建立了ＰＷＭ 变频调速系统动态性能精确计算的场—路模型和计算方法。重点探讨了电流的集肤效应计算、仿真过程中可能出现的数值振落的抑制以及定转子相对运动等问题，为此引入了插值运动的边界和数值临界阻尼法。Field Path model and calculation method are set up for dynamic performance to be accurately calculated in a system of PWM frequency conversion and speed regulation in the paper. It mainly discusses the calculation of the skin effect by electric current, the suppression of numerical vibration which may appear during simulation, and the problem on both the stator and the rotator moving relatively. For this purpose, the paper introduces a damping method resulting from interpolated motional boundary and numerical value critical. Finally, some of actual calculation examples are proposed herein.
