Hello,
I realize this is not electronics, but I thought I would try here anyway. I am trying to get an overview of generator output voltage-reactive power control (which is done by the Automatic voltage regulator and the exciter of the generator), but there is something I cannot seem to find answers to somewhere else.
When you control a synchronous generator with a drooping VQ-characteristics in real life, (maybe because you are operating several generators in parallel and you want to share the reactive power load), does the VQ-droop curve go into the negative quadrant of reactive power? Or is it similar to the power-frequency droop curve in that it is only kept within positive power?
The reason I ask is because the syn gen can be operated both for absorbing and supplying reactive power, so I was wondering if this is reflected in the droop characteristics of the VQ droop curve?
All comments and answers are appreciated!
