ABSTRACT
As previously discussed in Chapter 2, the induction generator has a serious limitation: an inherent need for reactive power. It consumes reactive power when connected to the distribution network, and, actually, it needs an external reactive source permanently connected to its stator windings to provide output voltage control. This source of reactive power keeps the current going through the machine windings needed to generate the variable magnetic eld. The movement of the rotor conductors causes the voltage across the induction generator terminals. Another way of inducing this voltage is to use the residual magnetism associated with an external capacitor that generates current by rotor movement inside this magnetic eld, inducing voltage as described in the following.
