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.

SSE Plc
SSE plc (formerly Scottish and Southern Energy plc) is a multinational energy company headquartered in Perth, Scotland. It is listed on the London Stock Exchange, and is a constituent of the FTSE 100 Index. SSE operates in the United Kingdom and Ireland. History Origins The company has its origins in two public sector electricity supply authorities. The former North of Scotland Hydro-Electric Board was founded in 1943 to design, construct and manage hydroelectricity projects in the Highlands of Scotland, and took over further generation and distribution responsibilities on the nationalisation of the electricity industry within the United Kingdom in 1948. The former Southern Electricity Board was created in 1948 to distribute electricity in Southern England. Whilst the Southern Electricity Board was a distribution only authority, with no power generation capacity of its own, the North of Scotland Hydro-Electric board was a broader spectrum organisation, with its own genera ...

Electrical Grid
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of:Kaplan, S. M. (2009). Smart Grid. Electrical Power Transmission: Background and Policy Issues. The Capital.Net, Government Series. Pp. 1-42. * power stations: often located near energy and away from heavily populated areas * electrical substations to step voltage up or down * electric power transmission to carry power long distances * electric power distribution to individual customers, where voltage is stepped down again to the required service voltage(s). Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power throughout the area, connecting a large number of electricity generators and consumers and poten ...

Newcastle Upon Tyne
Newcastle upon Tyne ( RP: , ), or simply Newcastle, is a city and metropolitan borough in Tyne and Wear, England. The city is located on the River Tyne's northern bank and forms the largest part of the Tyneside built-up area. Newcastle is also the most populous city of North East England. Newcastle developed around a Roman settlement called Pons Aelius and the settlement later took the name of a castle built in 1080 by William the Conqueror's eldest son, Robert Curthose. Historically, the city’s economy was dependent on its port and in particular, its status as one of the world's largest ship building and repair centres. Today, the city's economy is diverse with major economic output in science, finance, retail, education, tourism, and nightlife. Newcastle is one of the UK Core Cities, as well as part of the Eurocities network. Famous landmarks in Newcastle include the Tyne Bridge; the Swing Bridge; Newcastle Castle; St Thomas’ Church; Grainger Town including G ...

Neptune Bank Power Station
Neptune Bank Power Station was a coal-fired power station situated on the River Tyne at Wallsend near Newcastle upon Tyne. Commissioned in 1901 by the Newcastle upon Tyne Electric Supply Company, the station was the first in the world to provide electricity for purposes other than domestic and street lighting. It was also the first in the world to generate electricity using three-phase electrical power distribution at a voltage of 5,500 volts. The station had an initial generating capacity of 2,800 kW, which was increased to 3,000 kW a year after the station opened, with the introduction of two 1,500 kW Parsons turbo alternators, the largest ever built at that time. The station closed in 1915, following the completion of an extension to Carville Power Station and the opening of Dunston Power Station. History At the beginning of the twentieth century, the use of electricity for general purposes began to be considered, and the Newcastle upon Tyne Electric Su ...

Electric Power Distribution
Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between and with the use of transformers. ''Primary'' distribution lines carry this medium voltage power to distribution transformers located near the customer's premises. Distribution transformers again lower the voltage to the utilization voltage used by lighting, industrial equipment and household appliances. Often several customers are supplied from one transformer through ''secondary'' distribution lines. Commercial and residential customers are connected to the secondary distribution lines through service drops. Customers demanding a much larger amount of power may be connected directly to the primary distribution level or the subtransmission level. The transition from transmission to distri ...

Three-phase Electric Power
Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by multiple people. Three-phase power works by the voltage and currents being 120 degrees out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Three-phase power is mainly used directly to power large inductio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
