HVDC converter station - Wikipedia
An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. [1] It converts direct current to alternating current or the reverse.
Although LCC HVdc grids or hybrid VSC/LCC HVdc grids are possible, this article focuses on VSC HVdc grids, their substation lay out, and how they differ from their ac counterparts. HVdc substations consist of a dc switchyard connecting multiple lines or cables and, possibly, one or more converter stations.
