安装完成后，插入硬件锁（Hardware Locks），可以是并口、串口或USB接口，视用户所购买版本不同而不同。双击 ，第一次打开软件，将会出现如下提示，图2.8，既没有取得有效认证，软件将会运行在功能受限的student版本下（参见第一章）。
实例（Instances）
元件实例是元件定义的图形“拷贝”，即通常所看到及应用在工程中的实体。准确来讲它不单是拷贝，因为在一个多元件系统中，同一元件定义可以在一个案例工程中生成多个实例，每一个实例都有自己的实体，而且可以设定不同的参数，甚至是不同于其他实例的图形外观。
3.1.2
模块是一种特殊形式的元件，它由基本元件组合而成，而且可以包含其他模块，从而可以形成分层系统结构。其运行方式相当于普通的元件，除非其不允许参数输入。
•研究在谐波谐振，控制，交互作用等引起的不稳定性；
•研究柴油机和风力发电机对电力网的冲击影响；
•绝缘配合；
•各种类型可变速装置的研究，包括双向离子变频器，运输和船舶装置；
•工业系统的研究，包括补偿控制，驱动，电炉，滤波器等；
•对孤立负荷的供电；
