In the first converter stations the alternating current (AC) is transformed into direct current (DC), which is transmitted via cable to the second converter station on the other side of the link, where it is transformed back to AC. HVDC Plus is a highly controllable and flexible system and brings operational benefits to both transmission systems.

High-voltage direct current - IPFS

At the heart of an HVDC converter station, the equipment which performs the conversion between AC and DC is referred to as the converter.Almost all HVDC converters are inherently capable of converting from AC to DC (rectifiion) and from DC to AC (), although in many HVDC systems, the system as a whole is optimised for power flow in only one direction.

Siemens at CIGRE 2018: Unlock the potential of

CIGRE 2018 took place at Paris from August 25th until 31st. Digitalization provides the key to success in the increasingly distributed energy landscape. Siemens experts explained how to make these changing energy systems even more safe and efficient. Digitalization enables predictive planning and new business models beyond just the provision of grid capacity.

Compact High Voltage Direct Current (HVDC) Transmission

A major driver for developments of new offshore HVDC connections is the ability to decrease the size of the station. Optimization of the converter station may reduce the size with 50%, which drives down cost of the platform. One component to reduce the size of the station is to shift from air insulated DC switchyard to DC-GIS.
