HVDC converter station

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. In addition to the converter, the station usually contains:

• three-phase alternating current switch gear
• transformers
• capacitors or synchronous condensers for reactive power
• filters for harmonic suppression, and
• direct current switch gear.
