Hi everybody
I have a question regarding synchronous generator terminal short-circuit. When the generator operates at full torque, and there is a short-circuit in generator terminals, torque starts to oscillate from positive to negative and back (and also starts to dampen). What about the direction of the first torque peak, which has the highest amplitude.. Is it always in the same direction as the rated operating torque, or is it in the opposite direction? If it is in the same direction as rated torque, it means that the first peak would have to be added on top of the rated torque, second option would mean that the first peak would have to be extracted from rated torque to get the total torque on the shaft.
Could someone explain which one is correct? I hope I was clear enough.
Thanks.
