The introduction of HVDC section inside an electric system requires that the transmission operator or the investor, if we are talking about a merchant line, to produce a study of different parameters for the best technical/economic evaluation of the investment. What we do CESI, an international leader for HVDC interconnections, can support its Clients in each part of the project: System Specification System Studies Tender Technical Specifications & Tender Assistance Design Review Quality Assurance Factory Test Commissioning & Performance Test. Why CESI CESI has a long term worldwide experience in HVDC links. Among others, we would like to cite: Brazil-Rio Madeira; Spain – Balearics; Italy – Sardinia; Italy – France; Italy – Montenegro; Colombia – Panama; Italy – Greece; Italy – Corsica – Sardinia; Egypt – Saudi Arabia; Dubai – Iran; China - Three Gorges –Shanghai; China, Xianjabà –Shanghai. * "A high-voltage, direct current (HVDC) electric power transmission system uses direct current for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems.[1] For long-distance transmission, HVDC systems may be less expensive and suffer lower electrical losses. For underwater power cables, HVDC avoids the heavy currents required to charge and discharge the cable capacitance each cycle. For shorter distances, the higher cost of DC conversion equipment compared to an AC system may still be warranted, due to other benefits of direct current links."
