HVDC Light^® - a preferable power transmission system for renewable energies

摘要

Today''s growing energy market and demand for renewable energies has generated an increasing request for advanced transmission technologies. The transmission systems must be able to handle demanding conditions, such as long distance water crossing, but still have low power losses. During the last decade the HVDC Light^® has proven to be a preferable solution for such applications, in particular for offshore wind power. The main benefit of HVDC is that it uses dc transmission, instead of ac, which allows for asynchronous interconnections and suppresses the need for reactive power compensation. HVDC Light^®, based on the voltage sourced converter (VSC) technology, has great performance when it comes to both active and reactive power control and it is a low loss transmission system ready to connect the energies of tomorrow.
