A plant for transmitting electric power through HVDC comprises two converter stations (101, 102) interconnected by a bipolar direct voltage network (103) and each connected to an alternating voltage network (104, 105). Each converter station has a Voltage Source Converter with switching cells each including at least one energy storing capacitor. The Voltage Source Converters are configured to utilize a direct voltage having a higher magnitude for a first of the poles than for a second thereof with respect to ground. |
