ABSTRACT
InChapter 7, Vol. 1, we alluded to the induction generator mode both in stand-alone (capacitor excited) and grid-connected situations. In essence for the cage-rotor generator mode, the slip S is negative (S < 0). As the induction machine (IM) with a cage rotor is not capable of producing reactive power, the energy for the machine magnetization has to be provided from an external means, either from the power grid or from constant (or electronically controlled) capacitors [1–24].
