Excitation of synchronous machine
Excitation of synchronous machine
(OP)
I develop a simulation model of synchronous machine including excitation winding and damper winding. Everything works more or less reasonable except of the excitation.
Let's say that I have rotating diodes excitation. Is it possible to have pretty high excitation current in the excitation (field) winding while the input voltage is zero?
By input voltage I mean the voltage on the terminals of the diode rectifier. I would suggest that at zero-voltage input it is kind of open circuit so there should be no excitation current. Am I right or is it completely wrong point of view?
I can get lot of measurements from the site, unfortunately not this kind.
Do you have any suggestions?
Thanks for all your tips.
Best regards
Martin

If we learn from our mistakes I'm getting a great education!

In my case this behavior can take 2 seconds or more and the excitation current is nearly constant or even growing so I guess it is a mistake in the modeling.
