The single-phase self-excited induction generators (SPSEIG) are the best choice for supplying small and remote loads, where grid extension is not possible. The robust cage rotor construction, low cost, absence of exciter, self-protection against fault and stable operation are the essential advantages of the SPSEIG. The self-excitation of the SPSEIG is similar to that in the three-phase induction generators, as they are unable to generate their air gap magnetic field. So, in the isolated mode, they must be equipped with terminal capacitors, for supplying their air gap magnetic field in the form of reactive power.
