The class represents IEEE Std 421.5-2005 type ST4B model. This model is a variation of the Type ST3A model, with a proportional plus integral (PI) regulator block replacing the lag-lead regulator characteristic that is in the ST3A model. Both potential and compoundsource rectifier excitation systems are modeled.  The PI regulator blocks have nonwindup limits that are represented. The voltage regulator of this model is typically implemented digitally.<br /></p><p><br /></p><p>Reference: IEEE Standard 421.5-2005 Section 7.4. <br /></p>
