Dniester Hydro-accumulating Power Station
The Dniester Pumped Storage Power Station is a pumped storage hydroelectric scheme that uses the Dniester River northeast of Sokyriany in Chernivtsi Oblast, Ukraine. Currently, four of seven generators are operational and when complete in 2028, the power station will have an installed capacity of . Background As part of the Dniester Hydro Power Complex, the pumped storage power station (PSP) was planned in the 1970s along with two dams (Dniester I & II) and a nuclear power plant. In 1983, Dniester II, a dam which creates the PSP's lower reservoir, was completed. The PSP was approved by 1988 and construction began that same year. Three years later in 1991 though, construction was suspended due to a funding fallout from the dissolution of the Soviet Union. The project was re-approved in 1993 and construction commenced again in 2001. Project costs increased due to the poor state of the existing facilities which were not maintained while the project was suspended. On December 22, ...

Sokyriany
Sokyriany ( uk, Сокиряни, ; ro, Târgu Secureni) is a small city in Dnistrovskyi Raion, Chernivtsi Oblast ( province) of Ukraine, Northern Bessarabia. It hosts the administration of Sokyriany urban hromada, one of the hromadas of Ukraine. Population: History The oldest written mention of Sokyriany dates back to 1666, when the Ottoman troops conquered Moldova and Bukovina. In the Middle Ages, Sokyriany were part of the Moldavian principality. In January 1918, Soviet power was proclaimed in Sokyrian Oblast, and the confiscation of landlord lands began. In November 1918, Bessarabia, including the Sokiryan region, was occupied by Austro-German troops, thus royal Romania. After joining the USSR on November 12, 1940, the Bukovina Krai was formed Sokyryansky district. In the 60s of the 20th century, the territory of the Sokyrian region was part of the Kelmenets district. In the mid-1960s, Sokyryan district was restored within its previous administrative boundaries. City sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Load Balancing (electrical Power)
Load balancing, load matching, or daily peak demand reserve refers to the use of various techniques by electrical power stations to store excess electrical power during low demand periods for release as demand rises. The aim is for the power supply system to have a load factor of 1. Grid energy storage stores electricity within the transmission grid beyond the customer. Alternatively, the storage can be distributed and involve the customer, for example in storage heaters running demand-response tariffs such as the United Kingdom's Economy 7, or in a vehicle-to-grid system to use storage from electric vehicles during peak times and then replenish it during off peak times. These require incentives for consumers to participate, usually by offering cheaper rates for off peak electricity. Batteries and smart grid Telephone exchanges often have arrays of batteries in their basements to power equipment and in the past metro systems such as the London Underground had their own power ...

Buildings And Structures In Chernivtsi Oblast
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much art ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landmarks In Chernivtsi Oblast
A landmark is a recognizable natural or artificial feature used for navigation, a feature that stands out from its near environment and is often visible from long distances. In modern use, the term can also be applied to smaller structures or features, that have become local or national symbols. Etymology In old English the word ''landmearc'' (from ''land'' + ''mearc'' (mark)) was used to describe a boundary marker, an "object set up to mark the boundaries of a kingdom, estate, etc.". Starting from approx. 1560, this understanding of landmark was replaced by a more general one. A landmark became a "conspicuous object in a landscape". A ''landmark'' literally meant a geographic feature used by explorers and others to find their way back or through an area. For example, the Table Mountain near Cape Town, South Africa is used as the landmark to help sailors to navigate around southern tip of Africa during the Age of Exploration. Artificial structures are also sometimes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumped-storage Hydroelectric Power Stations In Ukraine
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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power Stations In Ukraine
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.

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] |
Embankment Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
