just follow those steps :

1- go Simulink Library

2-sinks

3-find (To work space block) and add it to your model

4-connect it to the STATCOM output

give it a name , for example y1

5-open the workspace and select from last option (Array)

6- when you finish running your model

7-you will find y1 in the workspace and how many values are in it

8- go to your command window

and copy and paste this code :

t=0:10/size(y1):10;

y1;

plot(t,y1)

I hope that helps

Sorry, when I run your model in my Matlab it gives me an error, I think we have different versions

connect three phase voltage current measurement block at the output of STATCOM

The Model which u selected is phasor type so you need to see these in phasor type simulation 

dear friend I try to connct measurement block but I think that this model must be correction.can you correct this and attach for me?
