显示 更早的评论
hello
someone who has already done this course can help me please?
in the represent power system component point there are a task whitout solution. i don´t know if its a mistake or im doing it wrong. the of the second module. i have done al the step they ask me to but the simulation still not working. i have followed the solution steps to see if its me but no, the simulation still not working. in the follow image as you can see this is the correct way to solve the problem but does not work

I was able to duplicate the issue. This is happening because the default value for one of the Wye-Connected Load block parameters has changed in R2024b.
Under Parasitics, change the Parasitic parallel conductance to 0. Keep the units as 1/Ohm.
Now when you submit, you should pass assuming everything else is correct.

Just got to this issue myself, was connecting the same output to the signal assessment to the scope to see how it looked on the scope, and form what I could tell there was no issues.
Setting the Parasitic Parallel Conductance to 0 as stated worked for me.
Thanks Cris

Ran into this issue and tried to fiddle with some parameters, watch videos to see if there was a bypass and no lluck. Saw this post and I did what you recommended with Parasitics setting and the error was clear.
Thank you for saving time and further headache.
