Analysis of HVDC and HVDC Light Technology
نویسنده
چکیده
Transmitting power at high voltage and in DC form instead of AC is a new technology proven to be economic and simple in operation which is HVDC transmission. The HVDC (High Voltage Direct Current) technology is used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems. A further development in this technology is HVDC light where HVDC light converters are used for faster and efficient conversion of power. HVDC Light is a fundamentally new power transmission technology developed recently. It is particularly suitable for medium to small-scale power transmission applications. This new transmission and distribution technology, HVDC Light provides an important role to today’s requirements on our network systems and opens up new opportunities for both investors and environmentalist alike. HVDC light technology for transmission of electric power is introduced in this paper. Its features, advantages and applications and comparison with simple HVDC system are pointed out. The paper gives a note on the advantages of HDVC light cables over AC underground cables.
