Neelum–Jhelum Hydropower Plant
The Neelum–Jhelum Hydropower Plant was part of a run-of-the-river hydroelectric power scheme in azad Kashmir Pakistan, designed to divert water from the Neelum River to a power station on the Jhelum River. The power station is located south of Muzaffarabad, and has an installed capacity of 969 MW. Construction on the project began in 2008 after a Chinese consortium was awarded the construction contract in July 2007. After delay of many years, the first generator was commissioned in April 2018 and the entire project was completed in August 2018 when the fourth and last unit was synchronized with the national grid on 13 August and attained its maximum generation capacity of 969 MW on 14 August 2018. It will generate 5,150 GWh (gigawatt hour) per year at the levelised tariff of Rs 13.50 per unit for 30 years. The plant had managed to reach 1040 MW production on a few occasions, which is beyond its capacity and a rare precedence in hydel power sector. Background After being approved ...

Kishanganga Hydroelectric Plant
The Kishanganga Hydroelectric Project is a run-of-the-river hydroelectric scheme in Jammu and Kashmir, India. Its dam diverts water from the Kishanganga River to a power plant in the Jhelum River basin. It is located near Dharmahama Village, north of Bandipore in the Kashmir valley and has an installed capacity of 330 MW. Construction on the project began in 2007 and was expected to be complete in 2016. It was halted in 2011 due to a dispute with Pakistan under the Indus Water Treaty, which went to a court of arbitration. Pakistan protested the effect of the project on the flow of the Kishanganga River to downstream areas in Pakistan-administered Kashmir. In December 2013, the Court ruled that India could divert water for power generation while ensuring a minimum flow of 9 cumecs (m3/s) downstream to Pakistan.

Hydraulic Head
Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum., 410 pages. See pp. 43–44., 650 pages. See p. 22. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well (a specialized water well), and given information of the piezometer's elevation and screen depth. Hydraulic head can similarly be measured in a column of water using a standpipe piezometer by measuring the height of the water surface in the tube relative to a common datum. The hydraulic head can be used to determine a ''hydraulic gradient'' between two or more points. "Head" in fluid dynamics In fluid dynamics, ''head'' is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid i ... [...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.

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for d ...

Penstock
A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is inherited from the earlier technology of mill ponds and watermills. Hydroelectric systems and dams Penstocks for hydroelectric installations are normally equipped with a gate system and a surge tank. They can be a combination of many components such as anchor block, drain valve, air bleed valve, and support piers depending on the application. Flow is regulated by turbine operation and is nil when turbines are not in service. Penstocks, particularly where used in polluted water systems, need to be maintained by hot water washing, manual cleaning, antifouling coatings, and desiccation. The term is also used in irrigation dams to refer to the channels leading to and from high-pressure sluice gates. Penstocks are also used in mine tailings dam construction. The penstock is usually situated fairly close to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Hammer
Hydraulic shock (colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid in motion, usually a liquid but sometimes also a gas is forced to stop or change direction suddenly; a momentum change. 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 described the effect of water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surge Chamber
Surge means a sudden transient rush or flood, and may refer to: Science * Storm surge, the onshore gush of water associated with a low-pressure weather system * Surge (glacier), a short-lived event where a glacier can move up to velocities 100 times faster than normal * Pyroclastic surge, the fluidised mass of turbulent gas and rock fragments ejected during some volcanic eruptions * Characteristic impedance, also known as "surge impedance" in electrical engineering * Voltage surge, short duration surges in electrical circuits * Compressor stall, also known as "compressor surge", in aviation * Surge in compressors in industrial compressors * Hydraulic surge in liquid pipes; also called pressure surge and water hammer (see surge control) * Surge (translational motion), one of the translational degrees of freedom of any stiff body (for example a vehicle), describing motion along the longitudinal axis (forward or backwards) * Surge (waves), transient or periodic motion in the direct ...

Pondage
Pondage usually refers to the comparably small water storage behind the weir of a run-of-the-river hydroelectric power plant. Such a power plant has considerably less storage than the reservoirs of large dams and conventional hydroelectric stations which can store water for long periods such as a dry season or year. With pondage, water is usually stored during periods of low electricity demand and hours when the power plant is inactive, enabling its use as a peaking power plant in dry seasons and a base load power plant The base load (also baseload) is the minimum level of demand on an electrical grid over a span of time, for example, one week. This demand can be met by unvarying power plants, dispatchable generation, or by a collection of smaller intermittent en ... during wet seasons. Ample pondage allows a power plant to meet hourly load fluctuations for a period of a week or more. As a daily hydropeaking cycle of a hydro power plant with pondage results in fast rising river le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
