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. The Baishan Dam is located upstream and the Fengman Dam downstream.

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 circu ...

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 gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low- 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 Brünn, Austria-Hungary (now Brno, Czechia), obtained his first patent for an adjustable blade propeller turbine in 1912. ...

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 to oppose the horizontal pressure of water pushing against it. 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 foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the con ...

Jilin Province
Jilin (; alternately romanized as Kirin or Chilin) is one of the three provinces of Northeast China. Its capital and largest city is Changchun. Jilin borders North Korea ( Rasŏn, North Hamgyong, Ryanggang and Chagang) and Russia (Primorsky Krai) to the east, Heilongjiang to the north, Liaoning to the south, and Inner Mongolia to the west. Along with the rest of Northeast China, Jilin underwent an early period of industrialization. However, Jilin's economy, characterized by heavy industry, has been facing economic difficulties with privatization. This prompted the central government to undertake a campaign called " Revitalize the Northeast". The region contains large deposits of oil shale. Name The name "Jilin" originates from ''girin ula'' () , a Manchu phrase meaning "along the river", shortened to Kirin in English. This Manchu term was transcribed into ''jilin wula'' ( t , s ) in Chinese characters and shortened the first two characters, which are tran ...

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.

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 ...

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 inst ...
