Hi guys,
I work now with an inverter feeding a synchronous machine (load-commutated). The characteristic of the firing angle as a function of stator current is usually constant up to certain level and then it starts to fall.
In this case the firing angle is rising at the beginning with the...
Thanks a lot for your replies. I had similar opinion that it is possible to have high excitation current at zero field voltage applied to the exciter winding, but only during transients. The excitation current should be falling so that the voltage on the magnetizing inductance (-L*dif/dt) is...
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...
