High Voltage Direct Current Electricity – technical information
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages … See more High voltage is used for electric power transmission to reduce the energy lost in the resistance of the wires. For a given quantity of power transmitted, doubling the voltage will deliver the same power at only half the current: See more Advantages A long-distance, point-to-point HVDC transmission scheme generally has lower overall investment cost and lower losses than an equivalent … See more Converter At the heart of an HVDC converter station, the equipment which performs the conversion between AC and DC is referred to as the converter. Almost all HVDC converters are inherently capable of converting from AC … See more Corona discharge is the creation of ions in a fluid (such as air) by the presence of a strong electric field. Electrons are torn from neutral air, and either the positive ions or the electrons are … See more Electromechanical systems The first long-distance transmission of electric power was demonstrated using direct current in 1882 at Miesbach-Munich Power Transmission, … See more Generally, providers of HVDC systems, such as GE Vernova, Siemens and ABB, do not specify cost details of particular projects. Such costs are treated as Confidential Business Matters between the supplier and the client. Costs vary widely … See more Monopole In a monopole configuration one of the terminals of the rectifier is connected to earth ground. The … See more WebNational Grid owns the high voltage electricity transmission system in England and Wales … cryptocurrency current trends
