Dear all, good morning.
I need some help.
I’m developing a study of current transformer (CT) saturation in the face of networks with harmonic content for my master’s thesis.
What’s happening is that I’m trying to implement the circuit with a saturable transformer, and I’m getting an error when running the circuit using a current source in the primary.
In fact, I can only analyse the circuit with a voltage source.
Could someone please help me with this error?
Please see this FAQ section on the state source dependency error message. You can also find additional information in the PLECS online help under Using PLECS + Error Messages + State source dependency. Note in that section of the manual there are example models showing how to resolve the state-source dependency error.
Regarding your model, note that you can use a Sine Wave, Sum, and Controlled Current source to greatly simplify your model. The example below shows the setup for the first three harmonics.
