The class represents IEEE Std 421.5-2005 type AC3A model. The model represents the field-controlled alternator-rectifier excitation systems designated Type AC3A. These excitation systems include an alternator main exciter with non-controlled rectifiers. The exciter employs self-excitation, and the voltage regulator power is derived from the exciter output voltage.  Therefore, this system has an additional nonlinearity, simulated by the use of a multiplier<br /></p><p>whose inputs are the voltage regulator command signal, <b>Va</b>, and the exciter output voltage, <b>Efd</b>, times <b>K</b><b><sub>R</sub></b>.  This model is applicable to excitation systems employing static voltage regulators.<br /></p><p><br /></p><p><br /></p><p>Reference: IEEE Standard 421.5-2005 Section 6.3.<br /></p>
