HVDC Power Transmission - an overview | ScienceDirect Topics DC (HVDC) transmission is considered advantageous and in some cases superior to AC in applications such as long underwater cable crossing, long-distance bulk power transmission, stable AC interconnection, interties with low short-circuit levels, coupling 50/60 Hz systems, and long-distance underground cable systems [75–79].The feasibility and benefits of an HVDC link are thus ...
What is an HVDC (High Voltage Direct Current) Transmission ...· An HVDC converter station uses thyristor valves to perform the conversion from AC to DC and vice versa. The valves are normally arranged as a 12- pulse converter. The valves are connected to the AC system by means of converter transformers. The valves are normally placed in a building and the converter transformers are located just outside.
