Harmony Link
Harmony Link is a planned submarine power cable between Lithuania and Poland. The purpose of the cable is to finish the transition of the Baltic states from IPS/UPS to the synchronous grid of Continental Europe. History On 21 December 2018 Lithuanian electricity grid operator Litgrid and Polish electricity grid operator PSE signed agreement in order to start planning the cable. Project given official name Harmony Link. Construction works expected to start in 2023 and finish in 2025. About the project Harmony Link will connect the Zarnowiec substation in the Pomeranian region of Poland with the Darbenai substation in the Kretinga region of Lithuania. The key component of the interconnector is a 700 MW High Voltage Direct Current (HVDC) cable. The power link will be about 330 km long, of which about 290 km will be the offshore part.

Lithuania
Lithuania (; lt, Lietuva ), officially the Republic of Lithuania ( lt, Lietuvos Respublika, links=no ), is a country in the Baltic region of Europe. It is one of three Baltic states and lies on the eastern shore of the Baltic Sea. Lithuania shares land borders with Latvia to the north, Belarus to the east and south, Poland to the south, and Russia to the southwest. It has a Maritime boundary, maritime border with Sweden to the west on the Baltic Sea. Lithuania covers an area of , with a population of 2.8 million. Its capital and largest city is Vilnius; other major cities are Kaunas and Klaipėda. Lithuanians belong to the ethno-linguistic group of the Balts and speak Lithuanian language, Lithuanian, one of only a few living Baltic languages. For millennia the southeastern shores of the Baltic Sea were inhabited by various Balts, Baltic tribes. In the 1230s, Lithuanian lands were united by Mindaugas, Monarchy of Lithuania, becoming king and founding the Kingdom of Lithuania ...

Electric Power Transmission Systems In Lithuania
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] |
Submarine Power Cables

SwePol
SwePol is a -long monopolar high-voltage direct current (HVDC) submarine cable between the Stärnö peninsula near Karlshamn, Sweden, and Bruskowo Wielkie, near Słupsk, Poland. The link was inaugurated in 2000 and can transmit up to 600 MW power at a voltage of 450 kV. The cable has a cross section of . It runs for as an underground cable from the Stärno HVDC Station to the shore of the Baltic Sea. The long submarine cable comes ashore in Poland near Ustka at and runs underground for the remaining to Bruskowo Wielkie HVDC Static Inverter Plant. Unlike other monopolar HVDC schemes, Swepol uses a metallic return consisting of 2 cables with sections for the submarine portion of the line, and a single cable with sections for the land portions. Both stations use air-core inductance smoothing rectifiers of 225 mH and a weight of , with filters for the 11th, 13th, 24th, and 36th harmonics. Each filter consists of a coil and a capacitor switched in row. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NordBalt
NordBalt (also formerly known as SwedLit) is a submarine power cable between Klaipėda in Lithuania and Nybro in Sweden. The purpose of the cable is to facilitate the trading of power between the Baltic and Nordic electricity markets, and to increase the supply and energy security in both markets. History The project was originally suggested in 2004. Original project Swindlit was aimed at construction of the wind farm in the Baltic Sea and ensuring the electricity transmission to Sweden and Lithuania. The participants of this project were interested also in Kruonis Pumped Storage Plant as an accumulator of variable wind energy. In August 2006, the Lithuanian and Swedish transmission grid operators Lietuvos Energija and Svenska kraftnät agreed to launch a feasibility study of a possible interconnector. In February 2007, Lietuvos Energija and Svenska Kraftnät signed an agreement with Swedish consulting company SWECO International on preparation of feasibility study. The study ...

LitPol Link
LitPol Link is an electricity link between Poland and Lithuania which connects the Baltic transmission system to the synchronous grid of Continental Europe. It has a capacity of 500 MW and since 2021 it can operate in a synchronous regime. History In 2000, European Commission and the EBRD agreed to finance a feasibility study on the Poland–Lithuania transmission interconnection. The study was completed in September 2002. The connection is expected to increase Poland's electricity interconnection level from 2% to 4%. Parts of LitPol are on the EU "Projects of Common Interest" list in November 2015. On 29 September 2006 Polish President Lech Kaczyński and Lithuanian President Valdas Adamkus signed a joint declaration on the joint power grid project during their meeting in Warsaw. The memorandum of understanding to establish a joint interconnection operator was signed between Lietuvos Energija and Polish PSE-Operator in Vilnius on 8 December 2006.

Estlink
Estlink is a set of HVDC submarine power cables between Estonia and Finland. Estlink 1 is the first interconnection between the Baltic and Nordic electricity markets followed by Estlink 2 in 2014. The main purpose of the Estlink connection is to secure power supply in both regions to integrate the Baltic and Nordic energy markets. Estlink 1 History First plans for a submarine power cable between the Baltic and the Nordic regions were proposed in 1990s. Negotiations between Eesti Energia, Pohjolan Voima, Helsingin Energia, Graninge (now E.ON Sverige), Latvenergo, Statkraft and TXE Nordic Energy, a subsidiary of TXU (now Energy Future Holdings Corporation) started In 1999, and on 9 October 2001 a contract was signed in Tallinn. However, only after the harsh winter of 2002–2003 which resulted in an increased demand for power, the project of the submarine cable between Estonia and Finland got a boost. The letter of intention for underwater sea cable was signed between E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
