Żarnowiec Pumped Storage Power Station
The Żarnowiec Pumped Storage Power Station is a pumped-storage power station located about south of Żarnowiec, in Puck County, northern Poland. It was constructed between 1973 and 1983 and underwent a modernisation between 2007 and 2011, with the upper reservoir reconstructed in 2006. With a capacity of 680 MW, it is the largest hydroelectric power station in Poland. It uses four 170 MW Francis pump-turbines to send water from its lower reservoir, Lake Żarnowiec, up to an upper reservoir for storage. During periods of high power demand, the water is released back down to the turbines to produce power. Water is pumped back up during periods of low power demand, such as night time. The power station was originally intended to be a load balancer for Żarnowiec Nuclear Power Plant The Żarnowiec Nuclear Power Plant ( pl, Elektrownia Jądrowa Żarnowiec) was to be the first nuclear power plant in Poland.''A Country Study: Poland'', Library of Congress, Call Number DK4040 .P5 ...

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 clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megawatt
The watt (symbol: W) is the unit of 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 quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own 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, the rate at which 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 volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical ci ...

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines Radial turbine, radial and Axial flow turbine, 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 Hydraulic head, head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm.

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, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Żarnowiec
Żarnowiec ( csb, Żarnówc, German ''Zarnowitz'') is a village in the administrative district of Gmina Krokowa, within Puck County, Pomeranian Voivodeship, in northern Poland. It lies close to Żarnowieckie Lake, approximately west of Krokowa, north-west of Puck, and north-west of the regional capital Gdańsk. In 2005 the village had a population of 861. Żarnowiec was the location for the first Polish nuclear power plant ( Żarnowiec Nuclear Power Plant), but construction was stopped in 1990 due to protests of the local population and lack of funds. Recently, the construction plans are being reconsidered. History The earliest evidence of settlement in the region dates from the 8th century BC: the inhabitants were apparently linked with the Lusatian and East Pomeranian cultures. There was a settlement near the Żarnowiec lake from the seventh to the tenth century AD. A village known alternately as ''Sarnkow'', ''Sarnowitz'', ''Sarnowicz'' or ''Czarnowicz'' is first me ...

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.

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 powe ...
