Trevallyn Power Station
The Trevallyn Power Station is a run-of-the-river hydroelectric power station located in the northern Midlands region of Tasmania, Australia. The power station is situated on the Great Lake and South Esk catchment and is owned and operated by Hydro Tasmania. Technical details Part of the Great Lake and South Esk scheme that comprises three hydroelectric power stations, the Trevallyn Power Station is the final station and is located adjacent to the Tamar River north of Launceston, making use of daily flows down the South Esk River. A dam on the South Esk River diverts water through a -long penstock pipeline to the power station. Water flows underground for its entirety except for a short, -long, portion that leaves the ground near Pitt Avenue due to a valley intersecting the tunnel's course. The pipeline splits underground into four smaller pipes immediately before entry into the station's turbines. The water enters the penstock tunnel above sea level and leaves the power sta ...

Hydroelectric Power Stations In Tasmania
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Energy Infrastructure Completed In 1955
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Duck Reach Power Station
Duck Reach Power Station was the first publicly owned hydro-electric plant in the Southern Hemisphere, and provided the Tasmanian city of Launceston with hydro-electric power from its construction in 1895 to its closure in 1955. Construction The site was picked by Launceston city surveyor and engineer Charles St John David in 1892. The penstock ran diagonally down the hill into the centre of the rear of the power station where it channeled in to successively smaller pipes and finally to eight Siemens turbines. Drilling the tunnel The tunnel was drilled to a length of at a 1 to 110 grade. The tunnel was cut through the hill side instead of being piped around and it took 16 months to complete using pneumatic drills. Dolerite is so hard it took one week of eighteen 8-hour shifts cutting from both ends of the tunnel to cut just however the average speed of the drilling was about a week. Two men were killed in accidents. When both ends met it was found that the accuracy w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolerite
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French ', and ultimately from the Greek - meaning "act of crossing over, transition". Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2%), and ...

Poatina Hydroelectric Power Station
The Poatina Power Station is a conventional hydroelectric power station located in the Central Highlands region of Tasmania, Australia. The power station is situated on the Great Lake and South Esk and is owned and operated by Hydro Tasmania. Technical details Located in the Great Lake and South Esk catchment area, Poatina makes use of a descent from the Great Western Tiers to the Norfolk Plains in Tasmania's northern Midlands. Water from Great Lake is diverted via a tunnel to the edge of the Great Western Tiers where it plummets down a viable penstock line, which enters the ground again near the power station. The Poatina Power Station is located underground in a massive artificial cavern hence the name Poatina, Palawa for "cavern" or "cave". The headrace tunnel and penstocks were bored through mudstone with the aid of a Robbins Mole. Water leaves the power station via a roughly long tailrace tunnel and discharges into the Macquarie River via Brumbies Rivulet. Poa ...

Tamar River (Tasmania)
The Tamar River, officially kanamaluka / River Tamar, is a estuary located in northern Tasmania, Australia. Despite being called a river, the waterway is a brackish and tidal estuary over its entire length. Location and features Formed by the confluence of the North Esk and South Esk rivers at , kanamaluka / River Tamar flows generally north towards its mouth at Low Head, north of the settlement George Town and into the Bass Strait via Port Dalrymple. kanamaluka / River Tamar has several minor tributaries including the Supply River. Low Head Lighthouse is located at the tip of a peninsula, on the east side of the mouth of the river. The only full crossing of the river is the Batman Bridge in the relatively remote area of Sidmouth, around halfway up the river. The Tamar river is complicated in that it silts up frequently, a contributing factor to its slow decline in use. Over time dredging operations have been required. A scheme enacted between the 1920s and 1970s pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
