HVDC Italy–Greece
The HVDC Italy–Greece is a monopolar submarine power cable link between Italy and Greece with a maximum transmission power of 500 megawatts. It went in service in 2001. The HVDC Italy–Greece begins in the static inverter plant Galatina situated at in Italy and is implemented in its first as underground cables. Then it crosses the Ionian Sea as a long submarine cable. It reaches shore just a few kilometres south of Albanian border at , where the long overhead line to Arachthos Arachthos ( el, Άραχθος) is a former municipality in the Arta regional unit, Epirus, Greece. Since the 2011 local government reform it is part of the municipality Nikolaos Skoufas, of which it is a municipal unit. The municipal unit has an ... static inverter station situated at starts. The cathode is implemented as bare copper wire on the Italian site, the anode is installed in a bay in Greece at . Sites See also External links ABB website on HVDC Italy-GreeceTHE ITALY-GREEC ...

Italy
Italy ( it, Italia ), officially the Italian Republic, ) or the Republic of Italy, is a country in Southern Europe. It is located in the middle of the Mediterranean Sea, and its territory largely coincides with the homonymous geographical region. Italy is also considered part of Western Europe, and shares land borders with France, Switzerland, Austria, Slovenia and the enclaved microstates of Vatican City and San Marino. It has a territorial exclave in Switzerland, Campione. Italy covers an area of , with a population of over 60 million. It is the third-most populous member state of the European Union, the sixth-most populous country in Europe, and the tenth-largest country in the continent by land area. Italy's capital and largest city is Rome. Italy was the native place of many civilizations such as the Italic peoples and the Etruscans, while due to its central geographic location in Southern Europe and the Mediterranean, the country has also historically been home ...

Greece–Italy Relations
Greece and Italy enjoy special and very strong bilateral diplomatic relations. Modern diplomatic relations between the two countries were established right after Italy's unification, and are today regarded as cordial. The two states cooperate in the fields of energy, security, culture and tourism, and are major trading partners, both in exports and imports, and Greeks and Italians often exchange the phrase "una faccia, una razza", meaning "one face, one race". Greece and Italy share common political views about the Balkans, the Mediterranean Basin and the world, and are leading supporters of the integration of all the Balkan nations to the Euro-Atlantic family, and promoted the "Agenda 2014", which was proposed by the Greek Government in 2004 as part of the EU-Western Balkans Summit in Thessaloniki, to integrate the Western Balkan nations into the EU by the year 2014, when Greece and Italy assumed the rotating Presidency of the European Union for the first and second halves of 20 ...

Electric Power Infrastructure In Greece
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of ...

HVDC Transmission Lines
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 between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics. HVDC allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems running at different frequencies, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 2001
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Static Inverter Plant
An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line.Arrillaga, Jos; High Voltage Direct Current Transmission, second edition, Institution of Electrical Engineers, , 1998. It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains: * three-phase alternating current switch gear * transformers * capacitors or synchronous condensers for reactive power * filters for harmonic suppression, and * direct current switch gear. Components Converter The converter is usually installed in a building called the valve hall. Early HVDC systems used mercury-arc valves, but since the mid-1970s, solid state devices such as thyristors have been used. Converters using thyristors or mercury-arc valves are known as ''line commutated converters''. In thyristor-based converters, many thyristors are conne ...

ABB Group
ABB Ltd. is a Swedish-Swiss multinational corporation headquartered in Zürich, Switzerland. The company was formed in 1988 when Sweden's Allmänna Svenska Elektriska Aktiebolaget (ASEA) and Switzerland's Brown, Boveri & Cie merged to create ASEA Brown Boveri, later simplified to the initials ABB. Both companies were established in the late 1800s and were major electrical equipment manufacturers, a business that ABB remains active in today. The company has also since expanded to robotics and automation technology. It is ranked 341st in the Fortune Global 500 list of 2018 and has been a global Fortune 500 company for 24 years. Until the sale of its Power Grids division in 2020, ABB was Switzerland's largest industrial employer. ABB is traded on the SIX Swiss Exchange in Zürich, Nasdaq Stockholm in Sweden, and the New York Stock Exchange in the United States. An ABB entity plead guilty for bid rigging in 2001, and the company has had 3 US Foreign Corrupt Practices Act bribin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
