Enron Wind
GE Wind is a division of GE Vernova. The company manufactures and sells wind turbines to the international market. In 2018, GE Wind was the fourth largest wind turbine manufacturer in the world. Vic Abate is the CEO of GE Vernova’s Wind businesses. History Enron Wind acquisition era (2002-2015) The entity was created as developer (not manufacturer) Zond in 1980 by James G.P. Dehlsen, who also formed Clipper Windpower in 2001. Enron acquired ''Zond'' and the German manufacturer ''Tacke Windtechnik'' in 1997. In 2002, while gas turbine sales were declining, GE acquired the Enron Wind, the only surviving US manufacturer of large wind turbines at the time, during the bankruptcy proceedings of its parent, Enron. GE increased engineering and support for the Wind Division and doubled its annual sales to $1.2B in 2003. By acquiring ''Zond'', GE gained a very important patent for variable-speed systems (), which had a major impact on the North American market. Enron had con ...

Alstom
Alstom SA () is a French multinational rolling stock manufacturer which operates worldwide in rail transport markets. It is active in the fields of passenger transportation, signaling, and locomotives, producing high-speed, suburban, regional and urban trains along with trams. The company and its name (originally spelled Alsthom) was formed by a merger between the electric engineering division of Société Alsacienne de Constructions Mécaniques (Als) and Compagnie Française Thomson-Houston (thom) in 1928. Significant acquisitions later included the Constructions Électriques de France (1932), shipbuilder Chantiers de l'Atlantique (1976), and parts of ACEC (late 1980s). A merger with parts of the British General Electric Company formed GEC Alsthom in 1989. Throughout the 1990s, the company expanded its holdings in the rail sector, acquiring German rolling stock manufacturer Linke-Hofmann-Busch and Italian rail signaling specialist Sasib Railways.

Nacelle
A nacelle ( ) is a streamlined container for aircraft parts such as Aircraft engine, engines, fuel or equipment. When attached entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a Hardpoint#Pylon, pylon or strut and the engine is known as a podded engine. In some cases—for instance in the typical "Farman Aviation Works, Farman" type Pusher configuration, "pusher" aircraft, or the World War II-era P-38 Lightning or SAAB J21—an aircraft cockpit may also be housed in a nacelle, rather than in a conventional fuselage. Etymology Like many aviation terms, the word comes from French language, French, in this case from a word for a small boat. Development file:Arado Ar 234V6 and Ar 234V8 front-view silhouettes.png, The development of the Arado Ar 234, merging the four nacelles into two The Arado Ar 234 was one of the first operational jet aircraft with engines mounted in nacelles.

Doubly-fed Electric Machine
Doubly fed electric machines, Doubly fed induction generator (DFIG), or slip-ring generators, are electric motors or electric generators, where both the field magnet windings and armature windings are separately connected to equipment outside the machine. By feeding adjustable frequency AC power to the field windings, the magnetic field can be made to rotate, allowing variation in motor or generator speed. This is useful, for instance, for generators used in wind turbines. Additionally, DFIG-based wind turbines offer the ability to control active and reactive power. Introduction Doubly fed electrical generators are similar to AC electrical generators, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. This is useful for large variable speed wind turbines, because wind speed can change suddenly. When a gust of wind hits a wind turbine, the blades try to speed up, but a synchronous generator is locked t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinetic Energy
In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2.Resnick, Robert and Halliday, David (1960) ''Physics'', Section 7-5, Wiley International Edition The kinetic energy of an object is equal to the work, or force ( F) in the direction of motion times its displacement ( s), needed to accelerate the object from rest to its given speed. The same amount of work is done by the object when decelerating from its current speed to a state of rest. The SI unit of energy is the joule, while the English unit of energy is the foot-pound. In relativistic mechanics, \fracmv^2 is a good approximation of kinetic energy only when ''v'' is much less than the speed of light. History and etymology The adjective ''kinetic'' has its roots in the Greek word κίνησις ''kinesis'', meaning "motion". The dichoto ...

Fibreglass
Fiberglass (American English) or fibreglass ( Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non- conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of Energy
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and energy production, the research and development of nuclear power, the military's nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the secretary of energy, who reports directly to the president of the United States and is a member of the Cabinet. The current secretary of energy is Chris Wright, who has served in the position since February 2025. The department's headquarters are in sou ...

IEC 61400
IEC 61400 is an international standard published by the International Electrotechnical Commission (IEC) regarding wind turbines. Purpose and function IEC 61400 is a set of design requirements made to ensure that wind turbines are appropriately engineered against damage from hazards within the planned lifetime. The standard concerns most aspects of the turbine life from site conditions before construction, to turbine components being tested,Woebbeking, Mike"IEC TS 61400-22"pages 1-2 and 9 ''Germanischer Lloyd'', 2008. Accessed: 12 March 2011Archive/ref> assembled and operated. Wind turbines are capital intensive, and are usually purchased before they are being erected and Project commissioning, commissioned. Some of these standards provide technical conditions verifiable by an certification body, independent, third party, and as such are necessary in order to make business agreements so wind turbines can be financed and erected. IEC started standardizing international certifica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterprise Value
Enterprise value (EV), total enterprise value (TEV), or firm value (FV) is an economic measure reflecting the market value of a business (i.e. as distinct from market price). It is a sum of claims by all claimants: creditors (secured and unsecured) and shareholders (preferred and common). Enterprise value is one of the fundamental metrics used in business valuation, financial analysis, accounting, portfolio analysis, and risk analysis. Enterprise value is more comprehensive than market capitalization, which only reflects common equity. Importantly, EV reflects the opportunistic nature of business and may change substantially over time because of both external and internal conditions. Therefore, financial analysts often use a comfortable range of EV in their calculations. EV equation For detailed information on the valuation process see Valuation (finance). : Enterprise value = :: common equity at market value (this line item is also known as "market cap") :: + debt at mar ...
