Busbar Configurations for HVDC Grids

E. Torres, P. Eguia, A. Iturregi, O. Abarrategui, A. Etxegarai



The development of HVDC grids requires analyzing the configuration of DC busbars for the connection of converters and for meshing the grid, taking into account the specific characteristics of DC regarding fault clearance and current interruption. In principle, similar busbar topologies to
those used in AC systems can be used. However, due to technical and economic considerations DC switchyards can be optimized by means of the combination of DC breakers of different
technologies. This paper reviews the main characteristics of DC fault current, its interruption and the different technologies of DC circuit breakers, as well as proposals from manufacturers and
researchers for the design and optimization of DC switchyards.
