A systematic terminology for the field of HVDC networks has been developed, closing the gap between the well-established terminologies from AC power systems and HVDC technology. The most relevant items, topologies and concepts have been given clear and unique defined names, and these have been classified in a systematic way.
The motivation for this work has been to help to reduce the communication problems that are emerging when power system engineers talk to HVDC technology engineers. The main guidelines underpinning the approach taken here is to minimise conflicts with the mentioned two existing terminologies and with existing publications on HVDC networks. A significant effort has been made to make the terminology "future-proof" not only covering today's HVDC technology but also potential future developments like large meshed HVDC grids and high power HVDC-HVDC converters.
