对于我们电气专业的仿真而言，我们主要用到的可能是Simulink工具箱，SimPowerSystem工具箱。当然也有可能涉及到SimExtra工具箱。但主要是实用前两者来进行电力系统，电力电子和电机等方面的仿真。因此在进行这些仿真的时候，有一些基本的原则：-For our simulation of electrical expertise, we may be used in Simulink main toolbox, SimPowerSystem toolbox. Of course, there may relate to SimExtra toolbox. But mostly for the first two practical power systems, power electronics and motor and other aspects of emulation. Therefore, when conducting these simulations, there are some basic principles:
