Abstract:
High voltage direct current (HVDC) transmission systems have gained prominence due
to their advantages over conventional alternating current systems. This is true especially
in the transmission of bulk energy over long distances and the interconnection of
asynchronous electrical systems. The first HVDC system was built in 1954 and since then
the technology used in these systems has undergone several improvements,
accompanying technological advances of power electronics devices. In recent years,
modular multilevel (MMC) converters have been introduced as having several advantages
over previous topologies. In this context, the main objective of this internship is the
modeling and implementation of MMC type converters as well as the development of a
control system for the converters when they form an HVDC link. For that, the RSCAD
electromagnetic transient simulation program was used. The results obtained were
satisfactory and demonstrated that the implemented system behaves according to results
reported in the literature.
