HVDC

An HVDC electric power transmission system may be less expensive and suffer lower electrical losses for long-distance transmission. In addition, HVDC avoids the heavy currents required by the cable capacitance for submarine power cables. HVDC also enables power transmission between asynchronous AC power grids, and can supply power to urban heavy load center.

NR’s complete HVDC transmission solutions are built upon the latest LCC-HVDC(Line Current Commutated HVDC) and VSC-HVDC(Voltage-Sourced Converter HVDC) technologies. Combined with deep system studies and design, NR offers “All-In-One” HVDC Transmission solutions with long-term warranty and long-lasting spare part supply to meet clients’ needs.

LCC-HVDC Transmission

Base on vast experience and strong technical background, NR offers LCC-HVDC solution package to both new and retrofit projects. The “All-In-One” LCC-HVDC solution package is composed of in-depth system study & design, high quality manufacturing, well system integration, FAT, commissioning and maintenance.

VSC-HVDC Transmission

VSC-HVDC Transmission

Compared to LCC-HVDC transmission, VSC-HVDC transmission has no limitation in minimum short circuit capacity, and thus it can be used in grid interconnection or directly connected to weak grids, such as power supply to island, city center infeed and decoupling to urban grid. Based on its strong technical background and vast experience over HVDC transmission project, NR ...
