Kyiv Pumped Storage Power Plant
The Kyiv Pumped-Storage Power Plant ( uk, Ки́ївська гідроакумулювальна електростанція) is a pumped-storage power station on the west bank of the Kyiv Reservoir in Vyshhorod, Ukraine. The Kyiv Reservoir serves as the lower reservoir and the upper reservoir is located above the lower. Water sent from the upper reservoir generates electricity with three conventional hydroelectric generators and three reversible pump-generators. During periods of low demand, such as night time, the pump-generators push water from the lower reservoir to the upper for use during peak hours. The first generator was commissioned in 1970, the last in 1972. History * 1963 - Beginning of the construction of the Kiev hydroelectric power plant. The underwater part of the HPP building and the installation site were built; * 1964 - filling of the Kievskaya HPP reservoir; * 1970 - commissioning of the first hydroelectric unit of the pumped storage power plant; * 1972 - ...

Kyiv Reservoir
The Kyiv Cistern ( uk, Київське водосховище, translit=Kyyivs’ke vodoskhovyshche), locally the Kyiv Sea, is a large Reservoir (water), water reservoir located on the Dnieper River in Ukraine. Named after the city of Kyiv, which lies to the south, it covers an area of within the Kyiv Oblast. The reservoir filled in 1964–1966 after the dam for the Kyiv Hydroelectric Power Plant was built at Vyshhorod. The reservoir is mainly used for hydroelectricity generation, industrial and public consumption, and irrigation. The reservoir is 110 km in length, 12 km in width, has a depth of four to eight meters, a volume of , and a usable volume of . The reservoir, together with the Kakhovka Reservoir, the Dnieper Reservoir, the Kamianske Reservoir, the Kremenchuk Reservoir, and the Kaniv Reservoir, has created a deep-water route on the river. However, its creation has also contributed to significant environmental problems such as the diminished flow velocity whi ...

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, 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 Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre 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 potentia ...

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 ...

Pumped-storage
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. The method 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 turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vyshhorod
Vyshhorod ( uk, Ви́шгород) is a city in Kyiv Oblast (region) in central Ukraine, situated immediately north of Kyiv city, the national capital, and part of the Kyiv metropolitan area. It is on the right (western) bank of the Dnieper river and, as the location of the Kyiv Hydroelectric Power Plant, the northern part of the city is beside the Kyiv Reservoir. It is the administrative center of Vyshhorod Raion and hosts the administration of Vyshhorod urban hromada, one of the hromadas of Ukraine. With a history dating back to the first millennium, Vyshhorod is now a notable industrial center and a growing commuter town for Kyiv. Its population is approximately Geography and climate Vyshhorod is located on a hilly right bank of the Dnieper river adjoining the dam of the Kyiv Reservoir. History The earliest historical mention of ''Vyshhorod'' (the name literally translates as " the town upstream") dates from as early as 946 when it was described as the favour ...

Ukraine
Ukraine ( uk, Україна, Ukraïna, ) is a country in Eastern Europe. It is the second-largest European country after Russia, which it borders to the east and northeast. Ukraine covers approximately . Prior to the ongoing Russian invasion, it was the eighth-most populous country in Europe, with a population of around 41 million people. It is also bordered by Belarus to the north; by Poland, Slovakia, and Hungary to the west; and by Romania and Moldova to the southwest; with a coastline along the Black Sea and the Sea of Azov to the south and southeast. Kyiv is the nation's capital and largest city. Ukraine's state language is Ukrainian; Russian is also widely spoken, especially in the east and south. During the Middle Ages, Ukraine was the site of early Slavic expansion and the area later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. The state eventually disintegrated into rival regional po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric
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 1970
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 whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
