OverexcLim2
Class Description
Different from LimIEEEOEL, LimOEL2 has a fixed pickup threshold and reduces the excitation set-point by means of a non-windup integral regulator. <i>Irated</i> is the rated machine excitation current (calculated from nameplate conditions: <i>V</i><i><sub>nom</sub></i>, <i>P</i><i><sub>nom</sub></i>, <i>CosPhi</i><i><sub>nom</sub></i>).
