The class represents IEEE Std 421.5-2005 type ST2A model. Some static systems utilize both current and voltage sources (generator terminal quantities) to comprise the power source.  The regulator controls the exciter output through controlled saturation of the power transformer components.  These compound-source rectifier excitation systems are designated Type ST2A and are represented by ExcIEEEST2A.<br/><br/>Reference: IEEE Standard 421.5-2005 Section 7.2. <br/>
