What was the technology of HVDC in 1990?
The development of HVDC systems in the last 10 years has three main avenues compared with the technology of 1990: 1. The traditional classic HVDC technology is still dominating but with improved equipment and sub-systems (e.g. valves, dc-bushings, AC-filters, DC-filters etc.) 2.
What is the role of Transformers in HVDC?
All modern HVDC valves are water-cooled and air insulated. Transformers: The converter transformers adapt the AC voltage level to the DC voltage level and they contribute to the commutation reactance.
