This excitation systems consists of an alternator main exciter feeding its output via non-controlled rectifiers. The exciter does not employ self-excitation, and the voltage regulator power is taken from a source that is not affected by external transients. Parameters of IEEE Std 421.5 Type AC1A Excitacion System. This model corresponds to ESAC1A in PSSE and PSLF
