Why are reactive power and voltage related? When the control system of a generator increases/decreases the current of the rotor, voltage and reactive power are increased/decreased.What is the relation between these two physics concepts? How comes and reactive power sustains voltage?
EDIT This question is definetely not a duplicate.Every synchronous AC generator has a field excitation. That means that there is DC current on its turning rotor. How comes that when this current is increased the reactive power produced is increased as well as the voltage?
