- a concrete gravity dam with a length of 1475 m and a height of 105 m, consisting of a station dam with a length of 396 m, an overflow dam with a length of 242 m, and deaf parts of the dam (in the riverbed and banks) with a length of 837 m.
- left bank stone-earthen dam 1770 m long and 28 m high
- right-bank earthen (sand) dam 538 m long and 47 m high
- near the dam of the hydroelectric station with a length of 440 m.
The height of the upper reach above sea level (NPU) is 296 m. A road crossing is built along the hydroelectric dam, through which traffic is closed. There are no ship passages at the hydropower station, in the future it is planned to construct a ship lift.
The design capacity is 4,320 MW, the installed capacity is 3,840 MW, the average annual output is 21.7 billion kWh. The building of the hydroelectric power station has 16 radial-axial hydraulic units with a capacity of 240 MW each, operating at a working head of 90.7 m. The pressure structures of the hydroelectric power station (the length of the pressure front is 3.84 km) form a large Ust-Ilimsk reservoir area of 1922 km², with a total volume of 58.9 km³. When creating the reservoir, 154.9 thousand hectares of land were flooded, including 31.8 thousand hectares of farmland. 14.2 thousand people from 61 settlements were resettled. 11.9 million m³ of forest was cut down.
The power plant was designed by the Institute "Hydroproject".
Ust-Ilimsk HPP is controlled by OJSC Irkutskenergo, however, the dams of hydropower plants are in federal ownership, it is planned to transfer them to RusHydro.
Ust-Ilim hydroelectric station plays an important role in ensuring the sustainability of the energy system of Siberia. Aluminum and wood chemical production consumes a significant part of hydroelectric power. The hydropower plant has become the basis for the creation of the Ust-Ilimsk territorial production complex. The electric power generated by the hydropower plant is transmitted via high-voltage lines to the unified energy system of Siberia.
Back in the late 20s - early 30s of the 20th century, the attention of Russian scientists was attracted by a unique combination of highly efficient fuel and energy, mineral, forest and other resources concentrated in the territory of the Irkutsk region. Established during this period as part of the Gosplan of the USSR, the Angarsk Bureau conducted comprehensive studies and carried out economic calculations that showed the profitability and prospects of creating energy-intensive industries based on hydrotechnical resources of the Angars - chemical processing of wood, chemistry, metallurgy.
In 1935, under the direction of Professor V.M. Malyshev, the first stage of research work on the Angara problem was completed, the result of which was: a scheme for using the upper section of the Angara, a schematic project of the primary Baikal “Irkutsk” hydraulic installation and a technical and economic scheme of the Pribaikalsky industrial complex, its consumers energy. These materials in 1936 were reviewed by an expert commission of the USSR State Planning Committee. The result of consideration was the decision to build on the river. The hangar of six hydroelectric power plants, forming a continuous cascade. Of all the Angarsk hydropower stations, the first priority was set by the Irkutsk Hydroelectric Power Station.
В 1959 Moscow State Institute of Designing Power Plants and Substations founded in s. Nevon Angarsk complex survey party to study the thermal regime of the Angara, the direction of future high-voltage transmission lines. In September 1960 The State Commission made a decision: to recognize the most appropriate place for the construction of the Ust-Ilimsk hydroelectric station, 20 km below the mouth of the river. science, on the Angara, at the rocky Cape Thick.
By a decree of the Central Committee of the CPSU and the Council of Ministers of the USSR of June 8, 1962, the start of construction and the installed capacity were determined. August 22 1962 An order was issued to start preparatory work for the construction of the Ust-Ilimsk hydropower station.
In accordance with the project, the construction of the Ust-Ilimsk HPP was divided into two phases. The first - the preparatory work - was five years: from 1963 по 1967. During this time, a construction site was mastered on the left bank of the Angara, auxiliary production enterprises: concrete, reinforcement plants, car repair shops, a settlement of hydrobuilders, the Bratsk- power line was laid.Ust-Ilimsk. In June 1966 A continuous passage through the highway from Bratsk to the future Ust-Ilimsk hydropower station was opened. In March 1966 work began on the main structures of the hydraulic system. This date is considered the official beginning of the construction of hydroelectric power plants. In February 1967 the first overlap of the Angara was made. WITH 1968 builders have begun to build major hydroelectric facilities. The second phase of construction began, lasting seven years: from 1968 по 1974.
People worked on one and a half shifts, they delivered lunch directly to the dredger. Dump trucks went with the maximum permissible speed. All works on the construction of hydropower plants went ahead of schedule also thanks to the creative approach to the business of hydraulic engineers. Therefore, already in 1967, the first overlap of the Angara took place, the first-trench pit was drained. The first cubic meter of concrete in the dam body was laid by the team of Nikolai Kornachev on April 22, 1968. From that moment 31 months passed and on December 1, 1970 the last rock block was laid on the section of the deaf dam [1, p. 3].
April 22 1968 The first cubic meter of concrete was laid in the hydroelectric dam. The second overlap of the Angara channel was made August 13 1969. October 3 1974 began filling the Ust-Ilimsk reservoir, it lasted until 1977. The first hydropower plant gave industrial current December 28th 1974, but May 20 1975 The hydroelectric power plant generated its first billion kWh of electricity. AT 1975—1977 4 units were introduced annually. the 25th of October 1977 with the launch of the 15th unit, the Ust-Ilim hydroelectric station was launched at full capacity of the first stage - 3,600 MW. In October 1978 The hydroelectric power station generated 50 billion kWh of electricity. In late March 1979 The last station, the sixteenth unit of the station, was connected to the network. December 1980 HPP was put into permanent operation.
1999- 500 billion kilowatt-hours generated.
2004- 600 billion kilowatt-hours generated.
Ust-Ilim hydroelectric station
high-pressure hydroelectric station of the dam type. The main structures of the hydroelectric complex include: a concrete gravity dam with a length of 1475 m and a height of 105 m, consisting of a station dam with a length of 396 m, a water overflow dam with a length of 242 m, and deaf dam parts (837 m), and a left-bank stone-earthen dam with a length of 1710 m and a height of 28m, and a right-bank earthen (sand) dam, 538 meters long and 47 meters high. The HPP building with a length of 440 m. Is located on the right bank directly behind the station part of the dam. It has 16 units with radial-axial turbines and umbrella-type generators [36, 128]. In 1981, the Ust-Ilim hydroelectric station produced the first 100 billion kWh, 200 billion kWh. - in 1986, 300 billion kWh - in 1991, 400 - in 1995, 500 billion kWh. - in 2000. As of March 18, 2002, a total of 530 billion kWh was produced. e / energy 194 people work at the Ust-Ilim hydroelectric station. Ust-Ilim hydroelectric station plays an important role in ensuring the sustainability of the energy system of Siberia. Aluminum and wood chemical production consumes a significant part of hydroelectric power. HPP has become the basis for the creation of the Ust-Ilimsk territorial production complex [1, p. 3].
March 29 2010 One of the 16 hydroelectric turbines was shut down. After the warning signal had been triggered, the hydraulic turbine was stopped in reserve and then taken to emergency repair to identify the causes of technological disruption and change the oil in the control system.
In the competition for repairs announced by the power company in May 2004 Along with Power Machines, Russian manufacturers of excitation systems participated - Uralelectrotyazhmash OJSC and Neva-Electromash CJSC.
В 2011 year, the repair program of the Ust-Ilimsk Hydroelectric Power Station will be overhauled by two hydrounits, will begin overhaul of another one, which will be completed in 2012m A few more units will be scheduled repairs. This will significantly improve the reliability of the main equipment.
At present, the overhaul of the hydraulic unit No. 14, which was started, is continuing at the Ust-Ilimsk Hydroelectric Power Plant. April 18th
