Hi,
I'm trying to understand the power systems library. I am coming from an optimization background and familiar with some power grid simulation software tools. However, I am having difficulties in understanding/interpreting the models within this library. I read the user's guide and went over the examples. Especially AC3ph is of interest to me.

I'd appreciate if anyone could give suggestions. Here are a couple of my questions (see the simple model attached):
1-How do I observe the natural coordinate (abc phase system) outputs?
2-How do I plot the sinusoidal of the  voltage source?
3-How do I observe neutral related information (especially for line components)?
4-Is there documentation somewhere explaining how to relate the real parameters/measurements  to the parameters of the library models (how can the info/test sheet obtained from a transformer manufacturer be used to set parameter values of a transformer model )?

Thank you very much in advance.
