Hello.
I am running a simulation (1 day with 1 min time step) of a simple network with solar panel and loads.
When I display the result of the voltage in the voltage profile(Mag) 3D graph I get a value of 230 V.
But when i display the voltage profile (p.u.) I get 0.8 p.u.
As the circuit is defined with kv=0.4 (RMS Line-to-Line), 230V should be 1 p.u. and not 0.8 p.u. (assuming voltage profile (Mag) displays the RMS Phase-to-line value).
How is the p.u. value calculated ?
are the assumption I make correct ?
Thank you for your help,
Lionel Bally
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Well, this situation normally happens when the voltage bases are not defined. In this case what you can do, is to create a control file with the DSS editor (Edit DSS File when the contructor is enabled), there insert a line declarig the voltage bases, for example:
Set Voltagebases=[115, 4.16, .48]
In this array you must include all the voltage bases. Then associate this file as a DSS Control file. Then everything should work fine.

Perfect ! Thank you very much.
