Reactive load
Generators operating in parallel distribute reactive current proportionally according to their rated capacity. Large capacity generators should carry more reactive load, while smaller capacity generators should negatively provide less reactive load. In order to realize the automatic distribution of reactive load, the excitation current of the generator can be changed by the excitation device with automatic high voltage regulation to keep the terminal voltage unchanged, and the inclination of the generator voltage regulation characteristic can be adjusted to realize the rational distribution of the reactive load of the parallel running generator.
