High-voltage direct-current (HVDC) transmission technology is used to convert the AC power produced in the wind farms to low-loss direct current. To accomplish this, several substations distributed throughout the wind farm transform the generated AC before it is converted to DC power by an HVDC platform. The electricity is transported onto land by a submarine cable, where it is converted back into AC. This technology is vital for cable lengths of more than 80 kilometers, as otherwise the transmission losses would be too great. ©
