EXAC1

Package: PowerDynamicsOpenAPIModels · Source: Dynamics/DynamicGeneratorComponent/AVR/EXAC1.json

Modified ESAC1A. 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. EXAC1 in PSSE and PSLF
