Western Isles HVDC Connection
The Western Isles HVDC connection is a proposed 1.8GW HVDC submarine power cable to connect the Isle of Lewis to the Scottish mainland. The project promoter, Scottish and Southern Electricity Networks, identifies the link as "one of the key investments across GB that is required to meet 2030 offshore wind targets, ndmarks a major step forward in unlocking the renewable energy potential of the Western Isles". Route The cable would connect Arnish, near Stornoway in Lewis to the National Grid at the Beauly substation. The island converter station and grid connection substation will be at Arnish Point in Lewis. From there, the marine cable will pass through ducts directly into the sea at 22m depth. 81km of subsea cable will carry the current to Dundonnell at the head of Little Loch Broom in Wester Ross. Around 75km of underground cable will carry HVDC to the converter station, which will have an 6km underground AC connection to the mainland transmission system at Beauly. ( ...

HVDC
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 Synchronization (alternating current), 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 run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Isle Of Lewis
The Isle of Lewis ( gd, Eilean Leòdhais) or simply Lewis ( gd, Leòdhas, ) is the northern part of Lewis and Harris, the largest island of the Western Isles or Outer Hebrides archipelago in Scotland. The two parts are frequently referred to as if they were separate islands. The total area of Lewis is . Lewis is, in general, the lower-lying part of the island: the other part, Harris, is more mountainous. Due to its larger area and flatter, more fertile land, Lewis contains three-quarters of the population of the Western Isles, and the largest settlement, Stornoway. The island's diverse habitats are home to an assortment of flora and fauna, such as the golden eagle, red deer and seal, and are recognised in a number of conservation areas. Lewis has a Presbyterian tradition and a rich history. It was once part of the Norse Kingdom of the Isles. Today, life is very different from elsewhere in Scotland, with Sabbath observance, the Scottish Gaelic language and peat cutting retainin ...

Stornoway
Stornoway (; gd, Steòrnabhagh; sco, Stornowa) is the main town of the Western Isles and the capital of Lewis and Harris in Scotland. The town's population is around 6,953, making it by far the largest town in the Outer Hebrides, as well as the third largest island town in Scotland after Kirkwall in Orkney and Lerwick in Shetland. The traditional civil parish of Stornoway, which includes various nearby villages, has a combined population of just over 10,000. The Comhairle nan Eilean Siar measures population in a different area: the ''Stornoway settlement'' area, Laxdale, Sandwick and Newmarket; in 2019, the estimated population for this area was 6,953. Stornoway is an important port and the major town and administrative centre of the Outer Hebrides. It is home to ''Comhairle nan Eilean Siar'' (the Western Isles Council) and a variety of educational, sporting and media establishments. Until relatively recently, observance of the Christian Sabbath (Sunday) has been associate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Grid (Great Britain)
In the electricity sector in the United Kingdom, the National Grid is the high-voltage electric power transmission network serving Great Britain, connecting power stations and major substations and ensuring that electricity generated anywhere on it can be used to satisfy demand elsewhere. The network covers the great majority of Great Britain and several of the surrounding islands. It does not cover Northern Ireland, which is part of a single electricity market with the Republic of Ireland. The GB grid is connected as a wide area synchronous grid nominally running at 50 hertz. There are also undersea interconnections to other grids in the Isle of Man, Northern Ireland, the Republic of Ireland, France, Belgium, the Netherlands and Norway. On the breakup of the Central Electricity Generating Board in 1990, the ownership and operation of the National Grid in England and Wales passed to National Grid Company plc, later to become National Grid Transco, and now National Grid plc.

Little Loch Broom
Loch Broom ( gd, Lochbraon, "loch of rain showers") is a sea loch located in northwestern Ross and Cromarty, in the former parish of Lochbroom, on the west coast of Scotland. The small town of Ullapool lies on the eastern shore of the loch. Little Loch Broom Its sister loch, Little Loch Broom ( gd, An Loch Beag, "the little loch"), lies just to the west, at the foot of An Teallach and opening into the Minch. The village of Dundonnell is located at the mouth of the loch, linked by the A832 coast road to Camusnagaul on the eastern shore, midway up the loch, and Badcaul further north. The loch is an important wildlife habitat, and a population of cormorants often bask on the rocks jutting out of the water. Geography Loch Broom Loch Broom is fed by the River Broom which rises in the Dirrie mountains, issuing from two lochs: Loch Bhraoin and Loch Droma. Loch Broom feeds the River Cuileig, which is joined by the Allt Breabaig stream that rises in Sgùrr Breac to the south. Loch ...

Shetland HVDC Connection
Shetland HVDC Connection is a high-voltage direct current submarine power cable under construction to connect Shetland to the British mainland. Current status In April 2022, the project was described as "on track to be completed by 2024". The subsea cable installation is ongoing, and expected to continue until 2023. Route The interconnector starts at the Upper Kergord Valley converter station in Shetland. From the converter station an underground cable runs to a landing area in Weisdale Voe. From there, a subsea cable runs to landfall at Noss Head in Caithness, with onward connection to an HVDC switching station north of the village of Staxigoe in Caithness. The route of the cable crosses TAT-10, TAT-14 and Atlantic Crossing 1 telecommunication cables and the Piper– Flotta oil pipeline. Technical description The interconnector will connect to the existing 320kV Caithness - Moray Link to form a three terminal HVDC network, with converter stations at Spittal in Caithne ...

Electrical Interconnectors To And From Great Britain
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 positiv ...
