Shunt voltage regulators for autonomous induction generators. Part II: circuits and systems

For pt. I, see ibid., p.262-5. The paper presents different kinds of circuits used for autonomous induction generator output voltage regulation. Operation of SVC (static VAr compensator) and STATCON (static condenser) based voltage regulators is explained, and the advantages and disadvantages of each type are shown. Different control strategies of voltage source and current source inverter based STATCONs are discussed. A novel current sensorless fixed frequency type of voltage regulator is also shown. In addition, extended simulation results are given, based on a real induction machine data.
