Traction Powerstation
A traction power station is a power station that produces only traction current, that is, electric current used for railways, trams, trolleybuses or other conveyances. Pure traction power stations are rare and there are many more power stations that generate current for other purposes, such as standard three-phase alternating current (AC), in addition to traction current. Examples Australia * Former Newport A Power Station, operated by the Victorian Railways in Melbourne. Germany * Muldenstein Bahnkraftwerk Muldenstein (German), in the former East Germany * Nuclear power station Neckarwestheim Nuclear Power Plant (GKN Block 1) The only nuclear power station that produces traction current directly with the world's largest generator for single phase AC. * Walchensee Hydroelectric Power Station, Bavaria. * Pump storage power station Langenprozelten. * Großkraftwerk Power Station in Mannheim. Norway * Hakavik Power Station * Kjofossen Power Station United Kingdom * Former Lots ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeast Corridor
The Northeast Corridor (NEC) is an electrified railroad line in the Northeast megalopolis of the United States. Owned primarily by Amtrak, it runs from Boston through Providence, New Haven, Stamford, New York City, Philadelphia, Wilmington, and Baltimore to Washington, D.C. The NEC closely parallels Interstate 95 for most of its length, and is the busiest passenger rail line in the United States both by ridership and by service frequency as of 2013. The NEC carries more than 2,200 trains daily. The corridor is used by many Amtrak trains, including the high-speed Acela, intercity trains and several long-distance trains. Most of the corridor also has frequent commuter rail service, operated by the MBTA, Shore Line East, Hartford Line, Metro-North Railroad, Long Island Rail Road, New Jersey Transit, SEPTA and MARC. While large through freights have not run on the NEC since the early 1980s, several companies continue to run smaller local freights over some select few sections ...

Amtrak's 25 Hz Traction Power System
Amtrak's 25 Hz traction power system is a Traction power network, traction power grid operated by Amtrak along the southern portion of its Northeast Corridor (NEC): the 226.6 route miles (362 km) between Washington, D.C. and New York City and the 104 route miles (167 km) between Philadelphia and Harrisburg, Pennsylvania. The Pennsylvania Railroad constructed it between 1915 and 1938. Amtrak inherited the system from Penn Central, the successor to the Pennsylvania Railroad, in 1976, along with the Northeast Corridor. This is the reason for using 25 Hz, as opposed to 60 Hz, which is the standard for power transmission in North America. In addition to serving the NEC, the system provides power to NJ Transit Rail Operations (NJT), the SEPTA, Southeastern Pennsylvania Transportation Authority (SEPTA) and the MARC Train, Maryland Area Regional Commuter Train (MARC). Only about half of the system's electrical capacity is used by Amtrak. The remainder is sold to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conowingo Dam
The Conowingo Dam (also Conowingo Hydroelectric Plant, Conowingo Hydroelectric Station) is a large hydroelectric dam in the lower Susquehanna River near the town of Conowingo, Maryland. The medium-height, masonry gravity dam is one of the largest non-federal hydroelectric dams in the U.S., and the largest dam in the state of Maryland. The dam sits about from the river mouth at the Chesapeake Bay, south of the Pennsylvania border and northeast of Baltimore, on the border between Cecil and Harford counties. The dam supports a 9,000-acre reservoir, which today covers the original town of Conowingo. During dam construction, the town was moved to its present location about northeast of the dam's eastern end. The rising water also would have covered Conowingo Bridge, the original U.S. Route 1 crossing, so it was demolished in 1927. U.S. Route 1 now crosses over the top of the dam. The Conowingo Reservoir, and the nearby Susquehanna State Park, provide many recreational opportu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Underground
The London Underground (also known simply as the Underground or by its nickname the Tube) is a rapid transit system serving Greater London and some parts of the adjacent ceremonial counties of England, counties of Buckinghamshire, Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway, the world's first underground passenger railway. Opened on 10 January 1863, it is now part of the Circle line (London Underground), Circle, District line, District, Hammersmith & City line, Hammersmith & City and Metropolitan lines. The first line to operate underground electric locomotive, electric traction trains, the City & South London Railway in 1890, is now part of the Northern line. The network has expanded to 11 lines, and in 2020/21 was used for 296 million passenger journeys, making it List of metro systems, one of the world's busiest metro systems.

Lots Road Power Station
Lots Road Power Station is a disused coal and later oil-fired and later gas-fired power station on the River Thames at Lots Road in Chelsea, London in the south-west of the Royal Borough of Kensington & Chelsea, which supplied electricity to the London Underground system. It is sometimes erroneously referred to as Fulham Power Station, a name properly applied to another former station a mile south-west along the Tideway. History A power station at Lots Road was originally planned by the Brompton & Piccadilly Circus Railway (B&PCR, now part of the Piccadilly line) in 1897. The B&PCR was controlled by the District Railway (DR, now the District line) from 1898, and was sold in 1901 to Charles Yerkes' Metropolitan District Electric Traction Company, which built the station to provide power to the DR. The station allowed the District line trains to change from steam haulage to electric. At around the same time the Metropolitan Railway built its power station at Neasden. The st ...
