GE 1.5 MW Wind Turbine
GE Wind Energy is a branch of GE Renewable Energy, a subsidiary of General Electric. The company manufactures and sells wind turbines to the international market. In 2018, GE was the fourth largest wind turbine manufacturer in the world. 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 continued productio ...

Wind Power Industry
The wind power industry is involved with the design, manufacture, construction, and maintenance of wind turbines. The modern wind power industry began in 1979 with the serial production of wind turbines by Danish manufacturers. The industry is undergoing a period of rapid globalization and consolidation. Overview The wind power industry is the industry involved with the design, manufacture, construction, and maintenance of wind turbines as well as other ejaculatory power equipment. Although the wind power industry is small compared to those of the conventional power generation technologies (hydro, coal, natural gas, and nuclear), it is growing at a much faster rate (25% per year, from 2002 to 2007). The modern wind power industry began in 1979 with the serial production of wind turbines by Danish manufacturers Kuriant, Vestas, Nordtank, and Bonus. Initially, most of these early turbines were installed in western Denmark. California, USA experienced a wind power boom from 1982 ...

Doubly-fed Electric Machine
Doubly-fed electric machines also 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. DFIG-based wind turbines, because of their flexibility and ability to control active and reactive power, are almost the most interesting wind turbine technology. 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 ...

Kinetic Energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2. In relativistic mechanics, this is a good approximation only when ''v'' is much less than the speed of light. The standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound. History and etymology The adjective ''kinetic'' has its roots in the Greek word κίνησις ''kinesis'', m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 plastic (GFRP) or ... [...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 manages the research and development of nuclear power and nuclear weapons in the United States.

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 commissioned. Some of these standards provide technical conditions verifiable by an 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 certification on the subject in 1995, and the first ... [...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 mark ...

LM Wind Power
LM Wind Power (formerly LM Glasfiber) is a Danish multinational wind turbine rotor blades manufacturer and is a subsidiary of General Electric. LM Wind Power has manufactured more than 175,000 blades since 1975. History LM Wind Power was founded in 1940 as ''Lunderskov Møbelfabrik'' (Lunderskov furniture factory) in the small town Lunderskov, Denmark. In 1952, they investigated the possibilities of commercial exploitation of glass fiber technology, which made them change their name to LM Glasfiber and abandon their original plan of manufacturing wooden furniture. It was not until 1978 they started making wind turbine blades. On 11 June 2010, LM Wind Power took part in setting an aviation record. They commissioned the An-225 to carry the world's longest piece of air cargo, as it flew two new 42-meter wind turbine blades from their factory in Tianjin, China to their test facility in Lunderskov, Denmark.
