EXAC2

Package: PowerDynamicsOpenAPIModels · Source: Dynamics/DynamicGeneratorComponent/AVR/EXAC2.json

Modified AC2. 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 AC2A Excitacion System. The alternator main exciter is used, feeding its output via non-controlled rectifiers. The Type AC2C model is similar to that of Type AC1C except for the inclusion of exciter time constant compensation and exciter field current limiting elements. EXAC2 in PSSE and PSLF
