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.

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 electricity generation, generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more Electric generator, generators, rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a Electrical conductor, 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, petroleum, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and use of renewable energy, renewables such as solar power, solar, wind power, wind, geothermal power, geothermal, and hydroelectricity, hydroelectric.

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 (electrical power), load balancing. A PSH system 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 water turbine, turbines to produce electric power. Pumped-storage hydroelectricity allows energy from Intermittent energy source, intermittent sources (such as solar power, solar, Wind power, wind, and other renewables) or excess electricity from continuous base-load sources (such as coal or nuclear) to be saved for periods of higher demand. The reservoirs used with pumped storage can be quite small, when contrasted with the lakes of conventional hydroelectric plants of ...

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 in the north to Washington, D.C., in the south, with major stops in Providence, Rhode Island, Providence, New Haven, Connecticut, New Haven, Stamford, Connecticut, Stamford, New York City, Newark, New Jersey, Newark, Trenton, New Jersey, Trenton, Philadelphia, Wilmington, Delaware, Wilmington, and Baltimore. The NEC is roughly paralleled by Interstate 95 for most of its length. Carrying more than 2,200 trains a day, it is the busiest passenger rail line in the United States by ridership and service frequency. The corridor is used by many Amtrak trains, including the high-speed ''Acela'' (formerly ''Acela Express''), intercity trains, and several Long-distance Amtrak routes, long-distance trains. Most of the corridor also has frequent Commuter rail in North America, commuter rail service, operated by the MBTA Commuter Rail ...

Amtrak's 25 Hz Traction Power System
The traction power network of Amtrak uses 25 Hz for the southern portion of the Northeast Corridor (NEC), the Keystone Corridor, and several branch lines between New York City and Washington D.C. The system was constructed by the Pennsylvania Railroad between 1915 and 1938 before the North American power transmission grid was fully established. This is the reason the system uses 25 Hz, as opposed to 60 Hz, which became the standard frequency for power transmission in North America. The system is also known as the Southend Electrification, in contrast to Amtrak's 60 Hz traction power system that runs between Boston and New Haven, which is known as the Northend Electrification system. In 1976, Amtrak inherited the system from Penn Central Transportation Company, Penn Central, the successor to the Pennsylvania Railroad, along with the rest of the NEC infrastructure. Only about half of the system's electrical capacity is used by Amtrak; the remainder is sold to the reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Holtwood Dam
Holtwood Dam (also Holtwood Hydroelectric Dam, Holtwood Hydroelectric Plant, McCalls Ferry Dam) is the oldest of three major dams built across the lower Susquehanna River, and the middle location of the three. It was constructed as the McCalls Ferry Dam between 1905 and 1910 by the Pennsylvania Water & Power (PW&P) Company. The dam was renamed Holtwood in honor of two company executives. PW&P merged with Pennsylvania Power & Light (PPL) in 1955. In 2015 Talen Energy took over PPL's generation and immediately sold the Holtwood plant to Brookfield Renewable Energy Partners to comply with federal antitrust requirements. Holtwood hydroelectric plant The Holtwood Hydroelectric Plant produces 252 Megawatts of power, using 14 turbine driven generators. The dam consists of a main concrete dam, which is mostly one continuous spillway, with a power house at the eastern end. The water level is raised by wooden flash boards and inflatable dam sections. The western end of the dam has th ... [...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, 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, river mouth at the Chesapeake Bay, south of the Pennsylvania border and northeast of Baltimore, Maryland, Baltimore, on the border between Cecil County, Maryland, Cecil and Harford County, Maryland, 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 in Maryland, U.S. Route 1 crossing, so it was demolished in 1927. U.S. Route 1 now crosses ove ...

London Underground
The London Underground (also known simply as the Underground or as the Tube) is a rapid transit system serving Greater London and some parts of the adjacent home counties of Buckinghamshire, Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway, opening on 10 January 1863 as the world's first underground passenger railway. The Metropolitan 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 with of track. However, the Underground does not cover most southern parts of Greater London; there are only 33 Underground stations south of the River Thames.

Lots Road Power Station
Lots Road Power Station is a disused gas- and oil-fired power station (originally coal) 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 and 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 Diistrict 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 ...
