Hydropower
Hydropower (from Ancient Greek -, "water"), also known as water power or water energy, is the use of falling or fast-running water to Electricity generation, produce electricity or to power machines. This is achieved by energy transformation, converting the Potential energy, gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for Hydroelectricity, hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce Carbon dioxide in Earth's atmosphere, carbon dioxide or other Air pollution, atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or ...

Watt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...

Vacha (river)
The Vacha () is a river in southern Bulgaria, a right tributary of the river Maritsa. The 112 km long Vacha is the 23rd longest river of Bulgaria and the second longest in the Rhodope Mountains, following the Arda (Maritsa tributary), Arda (272 km), another major Maritsa tributary. The Vacha drains significant area of the western Rhodope Mountains, including the ridges Batak Mountain, Veliyshko–Videnishki, Pereliksko–Prespanski and Chernatitsa. Geography The Buynovska reka is considered the main stem of the river and takes its source at an altitude of 1,558 m in the western Rhodope Mountains at 3.4 km southeast of the village of Kozhari, in the immediate vicinity of the border between Bulgaria and Greece. The main river is formed at the confluence of the Buynovska reka (left) and the Chairdere (right) at an altitude of 847 m in the village of Teshel.

Rhodope Mountains
The Rhodopes (; , ; , ''Rodopi''; ) are a mountain range in Southeastern Europe, and the largest by area in Bulgaria, with over 83% of its area in the southern part of the country and the remainder in Greece. Golyam Perelik is its highest peak at . The mountain range gives its name to the terrestrial ecoregion Rodope montane mixed forests that belongs in the temperate broadleaf and mixed forests biome and the Palearctic realm. The region is particularly notable for its karst areas with their deep river gorges, large caves and specific sculptured forms, such as the Trigrad Gorge. A significant part of Bulgaria's hydropower resources are located in the western areas of the range. There are a number of hydro-cascades and dams used for electricity production, irrigation, and as tourist destinations. Name and mythology The name of the Rhodope Mountains is of Thracian origin. Rhod-ope (Род-oпа) is interpreted as the first name of a river, meaning "rusty/reddish river", wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.

Dospat–Vacha Hydropower Cascade
The Dospat–Vacha Hydroelectric Cascade () is situated in the western Rhodope Mountains of southern Bulgaria, on the territory of the Smolyan Province, Smolyan, Pazardzhik Province, Pazardzhik and Plovdiv Provinces. It is owned by the NEK EAD, National Electricity Company. The cascade was constructed between 1963 and 2010 by "Hydrostroy". With catchment area of 2,083 km2 spanning from an altitude of 2,191 m at the summit of Golyam Perelik to 420 m at the Krichim Reservoir, it is among Bulgaria's most complex hydropower systems. The cascade receives water from several river drainages, mostly from the Nestos (river), Mesta, the Dospat (river), Dospat and the Vacha (river), Vacha. It includes five reservoirs and seven hydro power plants — Teshel Hydro Power Plant, Teshel, Devin Hydro Power Plant, Devin, Tsankov Kamak Hydro Power Plant, Tsankov Kamak, Orphey Hydroelectric Power Station, Orphey, Krichim Hydro Power Plant, Krichim and Vacha 1 and 2, with a combined ...

Hydroelectric Power Stations In Bulgaria
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, 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.
