Overvoltages Due to Harmonic Magnification in the Paraguayan AC Network Owing to AC Faults Close to the Itaipu' HVDC Station

摘要

The paper deals with overvoltages caused by harmonic magnification in the Paraguayan 220-66 kV network. The high harmonic distortion is due to faults within the 500 kV collector ring feeding the Itaipu' HVDC link. To compensate for this weakness of the Paraguayan network with respect to the Itaipu' system, alternative countermeasures such as series filters with harmonic dampers, or shunt filters with temporarily connectable shunt reactors, are considered.
