Transformers in HVDC Transmission
Matti Stoor
Andre Canelhas
Abstract
Power transformers are integral in the HVDC transmission systems and provide multiple functions. Correctly optimised transformers lower the cost for other equipment in HVDC schemes. This article describes the basics of HVDC and gives a view of where the HVDC development stands today. Both the LCC and VSC technologies are described, as well as newer converter concepts that lower losses and harmonic stresses. Finally the authors call for innovative solutions in order to boost the power density of transformers.
