HVDC transmission and the environment
Power Engineering Journal, 1996The increased use of electrical systems has led to significant changes in the electromagnetic environment (RFI, TVI, telephone interference, carrier-frequency interference). The extent to which large electrical systems, such as HVDC transmission networks, impinge on the environment has become a topical and even controversial issue. This article takes a

IEEE Potentials, 2014
The development of transmission systems closely follows the growing demand on electrical energy. With the increasing size and complexity of transmission networks, the performance of power systems decreases due to problems related to load flow, power oscillations, and voltage quality.

Telecommunications for HVDC Transmission
IEEE Transactions on Power Apparatus and Systems, 1968The control and operational principles of HVDC transmission are briefly reviewed. Basically no telecommunication is necessary for operation, with the exception of telephone connections. As the demand for service and system control increases, telecommunication requirements will grow. General requirements of telecommunications are summarized and specific

The thyristor valve in HVDC transmission
IEEE Spectrum, 1973The application of thyristor valves rather than mercury-arc valves for rectification in high-voltage dc transmission systems has increased. Schemes in service include Eel River in New Brunswick, Canada, the Gotland extension in Sweden, and the Sakuma extension in Japan.

HVDC transmission for large offshore wind farms
Power Engineering Journal, 2002Onshore and offshore wind farms are a rapidly growing worldwide industry. The development of larger, more efficient turbines is opening up new frontiers in wind energy generation in the form of large offshore wind farms. The use of high-voltage direct current (HVDC) technology can fully realise the potential of these developments, overcoming the major ...

Synchronverter based HVDC transmission
2017 Innovations in Power and Advanced Computing Technologies (i-PACT), 2017This is an innovative control strategy for the High Voltage Direct Current (HVDC) transmission based on synchronverter technology. The control of sending end rectifier mimics a synchronous motor(SM) and the receiving end inverter controls acts as a synchronous generator (SG).

HVDC Transmission: A Path to the Future?
The Electricity Journal, 2010Direct current transmission has been the poor stepchild of the U.S. electric industry. Although early-generation plants were based on DC technology, it was soon deemed uneconomical to transmit electricity over long distances, but it now appears poised for a change.

The limits of HVDC transmission
Energy Policy, 2013Abstract Renewable energy is abundant, but not necessarily near the urban centers where it will be used. Therefore, it must be transported; and this transport entails a systemic energy penalty. In this paper simple qualitative calculations are introduced to show (i) that high-voltage direct-current (HVDC) power lines for megameter and greater ...
