Olidan Power Station
Olidan Power Station ( sv, Olidans kraftverk) is a hydroelectric power station located in Trollhättan Municipality, Trollhättan, Sweden. First opened in 1910, it was the first large scale attempt at generating electricity from water in Sweden. The construction of Olidan led to the founding of the ''Kungliga Vattenfallsstyrelsen'' (Royal Waterfall Board), which later became Vattenfall. While the first four turbines were put into service in 1910, construction continued, and another four were put into operation by 1914. Due to increasing demand, as well as increasing capacity due to the regulation of Göta älv, another five were then built. By 1921, Olidan carried a total of 13 turbines. 10 of these are still functioning, while the other three were cannibalized for parts. However, it is currently rare for more than three to be generating at the one time. Each turbine has a capacity of 10 MW. When Olidan were completed in 1924, planning began for Hojum Power Station, which came in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Trollhättan Municipality
Trollhättan Municipality (''Trollhättans kommun'' or ''Trollhättans stad'') is a municipality in Västra Götaland County in western Sweden. Its seat is located in the city of Trollhättan. The municipality was created gradually in 1967, 1971 and 1974 during the last local government reform when the ''City of Trollhättan'' (itself instituted in 1916) was amalgamated with surrounding municipalities. The municipality itself prefers to use the denomination ''Trollhättans stad'' (''City of Trollhättan'') for the entire territory, including rural areas. This is purely nominal and has no effect on its status as a unitary municipality. Until 2012 it was the home of the now defunct Saab Automobile.

Sweden
Sweden, formally the Kingdom of Sweden,The United Nations Group of Experts on Geographical Names states that the country's formal name is the Kingdom of SwedenUNGEGN World Geographical Names, Sweden./ref> is a Nordic country located on the Scandinavian Peninsula in Northern Europe. It borders Norway to the west and north, Finland to the east, and is connected to Denmark in the southwest by a bridgetunnel across the Öresund. At , Sweden is the largest Nordic country, the third-largest country in the European Union, and the fifth-largest country in Europe. The capital and largest city is Stockholm. Sweden has a total population of 10.5 million, and a low population density of , with around 87% of Swedes residing in urban areas in the central and southern half of the country. Sweden has a nature dominated by forests and a large amount of lakes, including some of the largest in Europe. Many long rivers run from the Scandes range through the landscape, primarily ...

Electricity
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 p ...

Vattenfall
Vattenfall is a Swedish multinational power company owned by the Swedish State. Beyond Sweden, the company generates power in Denmark, Finland, Germany, the Netherlands, and the United Kingdom. The company's name is Swedish for "waterfall", and is an abbreviation of its original name, Royal Waterfall Board (''Kungliga Vattenfallstyrelsen''). History Vattenfall (then called ''Kungliga Vattenfallsstyrelsen'' or Royal Waterfall Board) was founded in 1909 as a state-owned enterprise in Sweden. From its founding until the mid-1970s, Vattenfall's business was largely restricted to Sweden, with a focus on hydroelectric power generation. Only in 1974 did the company begin to build nuclear reactors in Sweden (the Ringhals 1 and 2 reactors), eventually owning seven of Sweden's 12 reactors. In 1992, Vattenfall was reformed as the limited liability company Vattenfall AB. At the same time, the transmission grid (220 kV and 400 kV lines) was transferred to the newly formed state agency Svens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to ...

Göta älv
The Göta älv (; "River of (the) Geats") is a river that drains lake Vänern into the Kattegat, at the city of Gothenburg, on the western coast of Sweden. It was formed at the end of the last glaciation, as an outflow channel from the Baltic Ice Lake to the Atlantic Ocean and nowadays it has the largest drainage basin in Scandinavia. The Göta älv is located in Götaland, with the river itself being a site of early Geatish settlement. Its length is . The Bohus Fortress is located by the river at Kungälv. There the river splits into two, with the northern part being the Nordre älv and the southern part keeping the name Göta älv; the two arms of the river enclose the island of Hisingen. At Trollhättan there is a dam, canal locks and a hydropower station in the river. The locks make the river navigable, even for large cargo vessels ( long). The artificial parts are called Trollhätte Canal. The river and the canal is part of a mostly inland waterway, Göta Canal, which spa ...

Hojum Power Station
Hojum Power Station (alt. ''Håjum Power Station'') is the second hydroelectric power station in Trollhättan, the first one being the older Olidan Power Station. While the first two turbines were taken into service in 1938, a third one was built and started in 1992. The first two are rated at 50 MW, while the third is rated at 70 MW. The station is mainly located underground in a large mountain hall. This design was chosen because of the political instability in Europe at the time, which later led to the second world war. The relatively small building above ground was drawn by the Swedish architect An architect is a person who plans, designs and oversees the construction of buildings. To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings that h ... Erik Hahr.
