Punchiná Dam
The Punchiná Dam is an embankment dam on the Guatapé River east of San Carlos in Antioquia Department, Colombia. The dam creates Punchiná Reservoir, which is part of the San Carlos Hydroelectric Power Plant. The power plant was completed in two stages; the first was completed in 1984 and the second in 1987. It is the largest power station in Colombia. Background The project was initiated by Interconexión Eléctrica S.A. in 1973 and appraised in 1978. In May 1978, a World Bank loan was approved to help fund the dam and both stages of the power plant. Construction began in 1979, the dam was completed in 1983 and the last generator of stage one was operational in 1984. Stage two's final generator was operational in December 1987. The commissioning of stage two was originally slated for 1984 and stage one for 1983 but was delayed due to financial problems and redesigns. The total cost of stage one was US$443.7 million and stage two US$166.3 million. Design and operation The P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Carlos, Antioquia
San Carlos is a town and municipality in the Colombian department of Antioquia, part of the subregion of Eastern Antioquia. It is called the hydro-electrical capital of Colombia, because it has many dams and it produces much energy. The population was 14,480 at the 2018 census. History The site of the town was discovered by Captain Francisco Nuñez Pedroso. The town was founded on 14 August 1786. Geography The municipal area is 702 km². It has three ''corregimientos'', El Jordán, Puerto Garzas and Samaná del Norte. San Carlos is three hours away from the departmental capital, Medellín. The two are linked by a road.

Dams In Colombia
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Pelton Wheel
The Pelton wheel or Pelton Turbine is an Impulse (physics), impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less Energy conversion efficiency, efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energywhich made for a very efficient turbine. History file:Pelton wheel (patent).png, Figure from Lester Allan Pelton's original October 1880 patent Lester Allan Pelton was born in Vermillion, Ohio in 1829. In 1850, he traveled ov ...

Transformer
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple Electrical network, circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force, electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change Alternating current, AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underground Power House
An underground power station is a type of hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods. One or more conditions impact whether a power station is constructed underground. The terrain or geology around a dam is taken into consideration, as gorges or steep valleys may not accommodate a surface power station. A power station within bedrock may be less expensive to construct than a surface power station on loose soil. Avalanche-prone valleys often make a surface station unfeasible as well. After World War II, large hydroelectric power stations were placed underground more often in order to protect them from airstrikes. Often underground power stations form part of pumped storage hydroelectricity schemes, whose basic function is to level load: they use cheap or surplus off-peak power to pump water from a lower lake to an upper lake.

Water Hammer
Hydraulic shock ( colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly: a momentum change. It is usually observed in a liquid but gases can also be affected. This phenomenon commonly occurs when a valve closes suddenly at an end of a pipeline system and a pressure wave propagates in the pipe. This pressure wave can cause major problems, from noise and vibration to pipe rupture or collapse. It is possible to reduce the effects of the water hammer pulses with accumulators, expansion tanks, surge tanks, blowoff valves, and other features. The effects can be avoided by ensuring that no valves will close too quickly with significant flow, but there are many situations that can cause the effect. Rough calculations can be made using the Zhukovsky (Joukowsky) equation, or more accurate ones using the method of characteristics. History In the 1st century B.C., Marcus Vitruvius Pollio ...
