Hongshi Dam
The Hongshi Dam is a gravity dam on the Second Songhua River located east of Huadian in Jilin Province, China. The primary purpose of the dam is hydroelectric power generation and its power plant has an installed capacity of 200 MW. Construction on the dam began in 1982 and the reservoir began to fill in November 1985. The first generator was operational in December 1985 and the last in October 1987. The tall dam creates a reservoir with a normal storage capacity of . The dam is named after the town of Hongshi, located downstream.

Megawatt
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 ...

Kaplan-type
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted Wicket gate (hydraulics), wicket gates to achieve efficiency over a wide range of flow and hydraulic head, water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head (hydraulic), head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm (Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brno, Austria-Hungary (now in the Czech Republic), obtained his firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil. Stability of the dam primarily arises from the range of normal force angles viably generated by the foundation. Also, the stiff nature of a gravity dam structure endures differential foundation settlement poorly, as it can crack the dam structure. The main advantage to gravity dams over embankments is the scour-resistance of concrete, which protects against damage from minor over-topping flows. Unexpected large over-topping flows are still a problem, as they can scour dam foundations. A disadvantage of gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydroelectric
Hydroelectricity, or hydroelectric power, is Electricity generation, 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 energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.

Baishan Dam
The Baishan Dam (, ''meaning: "White Mountain Dam"'') is an arch-gravity dam on the Second Songhua River near the town of Baishanzhen, Huadian, Jilin Province, China. The purpose of the dam is hydroelectric power generation and flood control. The dam supplies water to five turbine-generators in two different powerhouses for an installed capacity of while it can also control a design flood. Additionally, it has a pumped-storage hydroelectric generation capacity. It is named after Baekdu Mountain (White Mountain), near the city of Baishan. Construction Construction on the dam began in May 1975, the reservoir began to fill on September 16, 1982 and by the end of 1984, the first phase of three generators was operational. Another two generators in the project's second phase were operational by 1992. The dam submerged an area of , displacing about 10,300 people. In March 2000, a feasibility study report on a pumped-storage capability for the dam was approved. In August 2002, cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fengman Dam
The Fengman Dam is a concrete gravity dam from Jilin City on the Second Songhua River in Jilin Province, China. The main purposes of the dam are hydroelectric power generation and flood control. Construction of the dam began in 1937 and was complete in 1953. The dam is owned and operated by Northeast China Grid Company Limited. A new dam was completed in 2019, and the old dam will be dismantled, except for a small section preserved for historical interest . History Construction on the Fengman Dam began in 1937 under the Japanese during their occupation of parts of China during World War II. In November 1942, the reservoir behind the dam began to fill and by March 1943, the first generators were operational. Still lacking floodgates, the dam was not entirely complete after the Japanese occupation in 1953. In 1959, the eighth and final generator of the first stage was installed, bringing the power station's installed capacity to 552.5 MW. Between 1970 and 1979, a tunnel was installe ...

List Of Dams And Reservoirs In China
Dams and reservoirs in China are numerous and have had a profound effect on the country's development and people. According to the World Commission on Dams in 2000, there were 22,104 dams over the height of operating in China. Of the world's total large dams, China accounts for the most – of them; of which are used for irrigation. Accordingly, the oldest in China still in use belongs to the Dujiangyan Irrigation System which dates back to 256 BC. In 2005, there were over 80,000 reservoirs in the country and over 4,800 dams completed or under construction that stands at or exceed in height. As of 2007, China is also the world's leader in the construction of large dams; followed by Turkey, and Japan in third. The tallest dam in China is the Jinping-I Dam at , an arch dam, which is also the tallest dam in the world.
