digsilent中模型开环测试设置完成后，如何运行？

在一份资料中看到model搭建完成后可以不连接其他设备，进行开环测试，操作如下：
. o7 u0 f$ i4 ?9 _
         Verify the behaviour of the model by an open-loop test, i.e. the controller is not connected to any
, G  v8 A$ J8 ]) yother element (synchronous generator) in the grid:
4 P. d; y/ J! S; U+ u  y  K$ h
Open-Loop Response:
 1    Test the model with a step response to the reference voltage “usetp” (open-loop-test) [17].
 2    Define a variable set to monitor for the VCO element and visualize the results of the simulated step response
$ a# ?8 x& u0 S

#17: Open-Loop Test
/ j, r; g0 S5 ~
 1     Open the event list ( ) and use the “New Object” button to insert a “Set Parameter(EvtPara)” event
 2     Select the AVR controller for the element.
5 p$ `) N( l$ I 3     Insert the name of the variable ‘usetp’ and the new value for this variable (=0.9).

补充：2    Define a variable set to monitor for the VCO element and visualize the results of the simulated step response

$ v3 Q/ ~0 x( H这一步也完成了，问：接下来怎么做？是执行计算初始条件然后开始仿真吗？

接下来就是定义一些你要观察的变量的值，然后做仿真，显示结果。
