Wushe Dam
Wushe Dam ( zh, c=霧社壩, p=Wùshè Bà) is a gravity dam forming Wushe Reservoir ( zh, c=霧社水庫, p=Wùshè Shuǐkù, labels=no), also called Wanda Reservoir ( zh, c=萬大水庫, p=Wàndà Shuǐkù, labels=no) and Bihu ( zh, c=碧湖, p=Bìhú, labels=no), on the Wushe Creek ( zh, c=霧社溪, p=Wùshè Xī, labels=no), a tributary of the Zhuoshui River, located in Ren-ai Township, Nantou County, Taiwan. The dam was completed in 1960 after seven years of construction and mainly serves to generate hydroelectric power. Background When Taiwan was under Japanese rule in 1934, hydroelectric plants were constructed at Sun Moon Lake to generate power from the fall of the Zhuoshui River. The Japanese also sought to build power stations upstream on Wushe Creek and Wanda Creek ( zh, c=萬大溪, p=Wàndà Xī, labels=no), the two main tributaries that combine to form the Zhuoshui. A reservoir would be required to control the flow of water to the power stations and serve the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wujie Dam
Wujie Dam () is a concrete gravity dam on the Zhuoshui River in Ren'ai Township, Nantou County, Taiwan. The dam was built in two stages, from 1919 to 1922 and 1927–1934, and serves primarily to divert water from the Zhuoshui River to a storage reservoir at Sun Moon Lake and its associated hydroelectric projects ( Mingtan Pumped Storage Hydro Power Plant and Minhu Pumped Storage Hydro Power Station). During the Japanese occupation of Taiwan it was known as Bukai Dam. The dam is located in a narrow gorge about northeast of Sun Moon Lake. It is high and long, forming a reservoir with a design capacity of , now mostly silted up. The diversion tunnel to Sun Moon Lake has a diameter of , with a diversion capacity of . The spillway of the dam consists of six gates with a capacity of . See also * List of dams and reservoirs in Taiwan This is a partial listing of dams and reservoirs in Taiwan (Republic of China).

Mingtan Dam
The Mingtan Dam () is a dam that spans the Shuili River about downstream from the outlet of Sun Moon Lake in central Taiwan with a height of about . It forms Mingtan Reservoir which is the lower reservoir for the Mingtan Pumped Storage Hydro Power Plant. History To meet the demand of the ever-increasing peak load in Taiwan and to fully utilize off-peak power, the Taiwan Power Company (Taipower) had entrusted European consultants to undertake feasibility study since 1973. The study showed the feasibility of constructing Mingtan Dam to meet such peak load demand, to avoid expanding current fossil-fuel power plants in Taiwan and to have lower operational cost. The dam was completed in 1994 and opened a year later. During the 7.7-magnitude 1999 Jiji earthquake, Mingtan was one of eight dams that sustained damage, but did not collapse. Mingtan Pumped Storage Hydro Power Plant The Mingtan Pumped Storage Hydro Power Plant is the largest hydroelectric power plant in Taiwan. It uses ...

Minghu Dam
The Minghu Dam (, renamed the Takuan Dam, is a concrete gravity dam on the Shuili River located north of Shuili Township in Nantou County, Taiwan. The reservoir formed by the dam serves as the lower reservoir for the Minhu Pumped Storage Hydro Power Station. Sun Moon Lake serves as the upper reservoir. The dam and the power plant was constructed in 1980 and opened on 1 August 1985. Upon completion, it became Taiwan's first pumped-storage hydroelectricity power plant. Takuan Power Plant The pumped-storage hydroelectricity power plant, officially named Takuan Power Plant, which sits near the left abutment of the dam and moves water between the two reservoirs to generate electricity. During periods of low demand, such as at night, when electricity is cheap, water is pumped to Sun Moon Lake. When energy demand is high, water is released down to the power station for power generation. This is accomplished by four Francis pump-turbine-generators which are reversible and serve to b ...

Kilowatt Hour
A kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ). Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) multiplied by (i.e., sustained for) one hour. The International System of Units (SI) unit of energy meanwhile is the joule (symbol J). Because a watt is by definition one joule per second, and because there are 3,600 seconds in an hour, one kWh equals 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publication 33 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Head
Hydraulic head or piezometric head is a measurement related to liquid pressure (normalized by specific weight) and the liquid elevation above a vertical datum., 410 pages. See pp. 43–44., 650 pages. See p. 22, eq.3.2a. It is usually measured as an equivalent 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. Definition In fluid dynamics, the ''head'' at some point in an incompressible (constant density) flow is equal to the height of a static column of fluid whose pressure at ...

Kilowatt
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 ...

Pelton Turbine
The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energywhich made for a very efficient turbine. History Figure from Lester Allan Pelton's original October 1880 patent Lester Allan Pelton was born in Vermillion, Ohio in 1829. In 1850, he traveled overland to take part in the California Gold Rush. Pelton worked by selling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
