Sažetak
HVDC is a technology which has been used for longdistance bulk power transfer, connecting different synchronous zones or submarine connections. Lately, HVDC has experienced a revival. In Europe, this revival is being driven by the strong increase in generation from renewable energy sources, the liberalization of the energy system, and the diffi culty in investing in new overhead transmission. In countries such as China, India and Brazil, the development is driven by a fast growth in energy consumption and the need for large amounts of energy, often from remote locations. HVDC transmission uses power electronic converters to interface between the alternating current (AC) grid and the direct current (DC) grid. Two types of HVDC exist: the traditional line commutated converter (LCC), which uses thyristors, and the voltage source converter (VSC), which uses insulated gate bipolar transistors (IGBT). LCC HVDC has the highest available ratings, but VSC offers better controllability and easier integration of cross-linked polyethylene (XLPE) cables for bidirectional power fl ow. HVDC is seen as the transmission technology of the future, specifi cally as the connection technology for renewable energy sources but also for a new backbone system. This new backbone system is expected to be in the form of a DC grid, with considerable parts of it being built using cable connections.
