Excursion to the HPP

Sayano-Shushenskaya hydroelectric power station - the largest power plant in Russia, which is located on the Yenisei River. Construction of the dam of this type in a broad alignment of the Yenisei River and the harsh climate of Siberia did not have analogues in the world. Today we went on a tour on the construction and try to learn some interesting facts about its creation. View of the hydroelectric power station on the lookout.





Sayano-built young. Komsomol organization in the construction originated in 1963, and in 1967 the Central Committee of the Young Communist League has announced the construction of the All-Union shock Komsomol building. So, sixteen girls - Mainskaya graduates high school - have decided to become constructors, and receive a trade-painters plasterers in uchkombinate Maina village. They have created a group, which was called "red scarf". Then everything came together in the evening branch Divnogorsk hydraulic College and successfully completed, after which many continued their education at universities, combining it with work on the building. A city of Makiyivka on Komsomol detachment arrived in the number of graduates of boarding 17 people. All "makeevtsy" also received a degree in Mainskaya uchkombinate. Photo Museum SSHHPP.



Year after year, building became more "Komsomol" and more all-Russian. In the summer of 1979 in the construction of the largest hydroelectric power station was attended by student construction teams total strength of 1,700 people in 1980 - more than 1,300 people from across the country. By this time the building has already formed its own 69 Komsomol youth teams, 15 of them - registered.



The largest industrial association for the Soviet Union created a new super-new hydropower equipment. So, all the unique equipment SS HPP were manufactured by domestic plants: hydro turbine - turbine building production association "Leningrad Metal Works", hydro - Leningrad Electrotechnical production association "Electrosila" Transformers - Production Association "ZTR". Turbine wheel were transported to the upper reaches of the Yenisei River waterway length of almost 10 000 kilometers, across the Arctic Ocean. Thanks to the original technical solution - installing the first two turbine wheels temporary workers capable of operating at intermediate pressure of the water - an opportunity before the end of construction and installation work to begin the first stage of the station. Due to this country's economy received an additional $ 17 billion. KWh of electricity. Having developed by 1986, 80 billion. KWh, building completely surrendered to the costs that went into its construction. Sayano-Shushenskaya hydroelectric power station began in the upper Yenisei cascade of hydroelectric power stations and one of the largest in the world, installed capacity - 6.4 mln. KWh and average annual production - 22.8 bln. Kilowatt-hour of electricity.



Pressure front of the power plant forms a unique concrete arch-gravity dam 245 m long at the crest of 1074.4 m, with a width at the base of 105.7 m and crest - 25 m. In terms of a dam in the upper 80-meter part is designed in the form of a circular arch having on the upper face radius of 600 m and a central angle of 102 °, and the bottom of the dam is a three-center arch, the central portion with a coverage angle of 37 ° formed arches same upper.



Mainskaya hydroelectric complex is located downstream of the Yenisei River 21.5 km from the power plant. Its main task - counter-regulation of its tailrace, which allows to smooth fluctuations in the river when the Sayano-Shushenskaya HPP is a profound control of the load in the power system. It is based on a conventional gravity dam and has a total capacity of hydroelectric unit 3 321 th. KW. Annual power Mainskaya HPS - 1.7 bln. Kilowatt-hour.



In Russia, mainly hydroelectric dams based on gravity. Also SSHHPP, arch-gravity dam have Gergebilskaya hydroelectric power plant in Dagestan, but it is much smaller.



The slopes of the mountains around hydroelectric resemble illustrations of the film about the agent 007.



Currently, "the Sayano-Shushenskaya HPP named after PS Neporozhny" is the most powerful source of electricity to cover peak drops in the Unified Energy System of Russia and Siberia. One of the major regional power consumers SSHHPP - Sayanogorsk Aluminium Smelter.



If you have a car, it can be left on the observation deck before the first checkpoint. End tram to pass office. Before parking service on a pedestal found one of the very temporary workers wheels of hydraulic units



Sayano-Shushenskaya hydroelectric power station is of particular interest as an object of tourism. At GES has its own museum. Due to sensitive sites, visiting the museum carried out through the regional tour operators, and may be a group visit to the museum by prior agreement with the administration of the museum and the school guidance HPP.



It's enough to call the HPP and arrange excursions. It is desirable to agree in advance, because in any case it will be necessary to agree with the security service.

To the right and below - OSG (outdoor switchgear), located in a small valley from which the electricity is on the transmission to consumers. To the left - under construction additional shore spillway.

The machine room power plant is based on spatial cross-bar structure, consisting of a unified system of metallic elements of the Moscow Architectural Institute (MARCHI). This design was first used in the practice of construction of hydroelectric power stations ... Turbine Hall floor and wall are fencing equipment and people from the outside and are only designed for snow and wind loads and seismic action in 7 points. Wherein loads associated with the action of the hydraulic processes by spillways and aggregates were not included. Because of this omission due to vibration once in 3 years, and certainly after each idle spillway should be examined thousands of nodes design the measurement gaps in the connecting nodes. You also can not avoid the presence of snow on the roof of a thickness exceeding 20 cm



The station was visited by a lot of experts from different countries, who celebrated a special architectural expressiveness and elegance of the machine room, which largely determines the appearance of the structure of the Moscow Architectural Institute. This is evidence that the architectural appearance design organization devoted so much attention that it was a success. So deep was worked out architectural and artistic part of the project of the upper structure of the machine hall is so insufficient attention was its technological performance.



Ten hydraulic turbines power plant was a new stage in the domestic gidroenergostroenii. Each turbine RO-230/833-B-677, fitted with impeller stainless cavitation steel 6, 77 meters in diameter and weighing 156 tons, able to develop the capacity of 650 000 kW at rated head 194 m. The first two generator power plant were commissioned temporary impellers of hydraulic turbines, capable of operating at low pressure, as the construction of facilities was carried out in stages. This allowed even at partial pressure, from 60 meters to generate electricity. Under huge slabs generators hidden heavy equipment and a few technical floors. In the distance you can see that the sixth unit is in scheduled maintenance - the generator of its partially dismantled.



Hydraulic turbine shaft upper flange is attached directly to the central part of the generator rotor mounted on top.



The total mass of each generator assembly - 1860 tons. Maximum assembly - 890 tons. But even 890 tons - beyond the power station construction crane machine hall, each of which has a limit of 500 tonnes. Therefore, when removing / installing the generator used both cranes in tandem.

Mounting platform with parts dismantled the hydraulic unit: the place where soon will be conducted electrical work.



Three device near the cross member to the recess of the generator - it's not actually part of the generator and the generator circuit breaker CAG-15, 75.



Such a switch at the station was left alone, and the rest are replaced with modern and more reliable ABB-shnye HEC8.



Currently, Sayano-Shushenskaya hydroelectric power station is the most powerful source of electricity to cover peak drops in the Unified Energy System of Russia and Siberia. One of the major regional power consumers - Sayanogorsk Aluminium Smelter, located not far from here, near the city of Sayanogorsk. Central control HPP.
