This first portion of the Atlantic Wind Connection will feature an Alstom kV HVDC transmission system that includes converters and. Alstom Grid’s HVDC demonstrator system with power converter modules. The improved controllability of the VSC in this system makes it well-suited for smart grid. Some of the major companies dominating the HVDC transmission market are ABB (Switzerland), Siemens (Germany), Alstom (France).

List of HVDC projects

Challenge Interconnect three or more regions and power systems to facilitate power exchange and trading, and to provide added system security, efficiency and flexibility to the benefit of the overall grid. Trusted project partner with a collaborative customer engagement model, extensive technical domain expertise resulting in optimized solutions that exceed customer expectations.

Retrieved akstom January ABB sets world record. Interconnecting Grids Challenge Interconnect asynchronous AC electricity grids to enable energy exchange, which provides dynamic reserve power support, relieve energy bottlenecks and maximize the efficient use of available power. Retrieved 25 September Line Commutated Converter is a mature cost effective HVDC technology based on thyristor power semiconductors, which enables the bulk transfer of power of up to 8 GW with lower losses and inherent DC fault protection.

Overhead Line, km Rating: Archived from the original PDF on February 16, Challenge To get power into congested cities to address increasing demand, lack of power highways and difficulties with establishing rights of way for a new grid. Benefits include Provides lowest loss solution, with the most efficient method of transmission technology Enables the controllability of intermittent power Maximizes the submarine cable capacity. Back to Back Rating: HitachiToshibaMitsubishi.

Where the power exchange or transmission crosses water, or an environmentally sensitive region, cables may be the favored method of interconnection between the HVDC Converter Stations. This is a list of notable high-voltage direct-current power transmission projects. Robust leading edge technology designed and built in advanced automated manufacturing and testing facilities to maximize quality and system performance.

Generally overhead lines are used for interconnectionbut an important class of HVDC projects use submarine power cables. HVDC transmission is particularly attractive and may be the only technically feasible method of transmitting power using cables. Benefits include Minimizes the visual impact of the power infeed on the local landscape Provides high levels of power injected directly to where it is needed Manages fault propagation providing a power “firewall” between the interconnected networks Provides lowest loss solution, with the most efficient method of transmission technology.
