本文介绍了由作者开发的通用电力电于系统仿真软件ＺＵＰＥＳＳ及其在斩波牵引系统的应用。由于斩波牵引系统惯性大，起动过程极长而斩波频率一般较高，如果采用二值开关模型模拟斩波器，仿真系统的起动过程需要较长的计算时间，仿真效率很低。为此我们提出了多级模型的仿真方法，即采用状态平均模型和开关模型相结合的多级模型，使仿真在保证应有精度的条件下具有较快速度、较高效率。
This article introduces the general power electronic system simulation software developed by the author ZUPESS and its application in the chopping traction system. Due to the large inertia of the chopper traction system, the extremely long starting process and the high chopping frequency, if the binary switch model is used to simulate the chopper, the startup process of the simulation system needs longer calculation time and the simulation efficiency is very low. To this end, we propose a multi-level model of the simulation method, that is, the use of the state average model and the switch model combined multi-level model, the simulation to ensure the accuracy of the conditions with faster speed, higher efficiency.
