Abstract
A plant for transmitting electric power through HVDC includes two converter stations interconnected by a monopolar direct voltage network and each having an alternating voltage side for feeding electric power from one of said alternating voltage sides to the other. Each station has a line commutated converter. The plant is upgraded by making the direct voltage network bipolar, providing each station with a Voltage Source Converter and providing two switches for both line commutated converters or both Voltage Source Converters and a device configured to control said four switches.
