Overvoltages on a series-compensated 750 kV system for the 10000 MW Itaipu project

The paper summarizes the most significant results of a Transient Network Analyzer study performed for the Itaipu transmission system in Brazil. This study considers an installed capacity of 10000 MW to be transmitted over 900 km from the Itaipu power plant to the São Paulo load area. Fault initiatio...

Description
Summary:The paper summarizes the most significant results of a Transient Network Analyzer study performed for the Itaipu transmission system in Brazil. This study considers an installed capacity of 10000 MW to be transmitted over 900 km from the Itaipu power plant to the São Paulo load area. Fault initiation, fault clearing, energization and reclosing overvoltages on two possible 750 kV ac schemes are mainly described. Emphasis is placed on some special transients which can be associated with series-compensated schemes and which can be of importance to insulation co-ordination, reclosing and equipment specification. Methods for controlling these transients are also proposed.
