UN 0820A-P Var.1 HIER 448925 R1 reactive power
When the generator runs in parallel with the system, it can be considered as running with the bus of the infinite capacity power supply. To change the excitation current of the generator, the induced potential and stator current will also change, and the reactive current of the generator will also change. When a generator is running in parallel with an infinite capacity system, the excitation current of the generator must be adjusted in order to change the reactive power of the generator. The change in the generator excitation current is not the usual “voltage adjustment”, but simply changes the amount of reactive power being fed into the system.
