High Voltage Direct Current (HVDC)Transmission Systems ...

1 Presented at Energy Week 2000, Washington, , USA, March 7-8, 2000 High Voltage Direct Current (HVDC)Transmission SystemsTechnology Review PaperRoberto CharpentierRaghuveer SharmaABB Power SystemsWorld BankABB Financial ServicesSwedenUnited StatesSwedenSynopsisBeginning with a brief historical perspective on the development of High Voltage Direct Current (HVDC)transmission Systems , this paper presents an overview of the status of HVDC Systems in the world today. Itthen reviews the underlying technology of HVDC Systems , and discusses the HVDC Systems from adesign, construction, operation and maintenance points of view. The paper then discusses the recentdevelopments in HVDC technologies. The paper also presents an economic and financial comparison ofHVDC system with those of an AC system; and provides a brief review of reference installations of HVDC Systems .

generated (by Thomas Alva Edison) was direct current (DC) electrical power. The first electricity transmission systems were also direct current systems. However, DC power at low voltage could not be transmitted over long distances, thus giving rise to …
