The biggest hydroelectric power plant in Russia
• The largest hydroelectric power plant in Russia
After a terrible accident in 2009 at the famous Sayano-Shushenskaya hydroelectric power station was six years ago, a year ago, then we finished the restoration work, now there is a repair and decoration.
I offer to walk on the largest hydroelectric power plant in Russia with a guided tour, to assess the volume of work done, and once again marvel at the scale of the largest in Russian hydropower complex.
from Abakan airport to the village of Cheryomushki, near which in 1963 began to build the power plant (Sayano-Shushenskaya HPP), a half-hour drive. After Sayanogorsk machines becomes much less, the road ends at the front of HPP, and then you can only get to the crest of the dam on the special permit.
Because of Cheryomushki, where most of the employees of the plant, to SSHGES runs a free tram that departs every hour.
The journey time on the bank of the Yenisei takes about 15 minutes, the distance from the end stations - less than six kilometers.
The tram arrives directly to the entrance. It's all serious - an armored box. After the terrorist attack on the Baksan hydroelectric power plant in Kabardino-Balkaria protection of all objects "RusHydro" was strengthened.
After a serious examination of how the airport, go through the territory of the Sayano-Shushenskaya HPP. The scale is quite difficult to play, but the man on the background of a concrete wall would look difficult-to-pixel.
SSHGES Installed capacity - 6,400 MW and average annual production - 23, 5 billion kWh of electricity. Pressure front power plant forms a concrete arch-gravity dam - unique size and complexity of the construction of hydraulic structures. The construction of high-pressure arch-gravity dam has no analogues in the world and domestic practice.
The chapel was opened at the foot of the first anniversary of Sayano-Shushenskaya HPP accident. I recall that there was a man-made disaster in the engine room 17 August 2009. The destruction of the hydraulic unit 2 occurred № water discharge from the turbine of the crater. The flow of water has been filled in the machine room, the force damaged, accessories, building construction collapsed machine hall of the building. All ten hydroelectric units are out of order. Killed 75 people.
The plaque, which all photographed.
The original fountain with "RusHydro" ball-logo, from which the flow of water flows dozens symbolizing HPP and flowing on the map of Russia.
In the lobby of the posters with diagrams and a description of the principles of hydroelectric works.
The first step is going to the brain of the Sayano-Shushenskaya hydroelectric power station - control room. Fully electronic scoreboard to replace the equipment, it was great, and an iron with a bunch of windows, sensors and arrows.
You can search on the net, and you can see the first remote control in the picture of the artist '80s.
On the one hand - the time in Moscow, on the other - at local Krasnoyarsk. Monitor the status of the dam of Sayano-Shushenskaya hydroelectric power plant - an ongoing process.
From a console window with a good view of the hydroelectric power station. The height of structures - 245 m, the ridge length - 1074, 4 m, the width at the bottom - 105, 7 m, along the ridge -. 25 m in plan view it has a circular arch radius of 600 m with a central angle of 102 degrees.
SSHGES dam is the highest in Russia and the 13th tallest in the world. While the Chinese are not built near their dam, we were in the top five ...
In the engine room HPP has 10 hydroelectric units with a capacity of 640 MW Francis turbines. The calculated pressure is 194 meters, the maximum static pressure - 220 m.
In memory of the victims.
The same section with hydraulic unit №2. New commissioned last fall. Now, after a year of operation, according to the rules of the manufacturer unit is stopped for routine inspection and maintenance.
The engine room is nearing completion of finishing works. By the way, at the entrance to the hall is struck by the fact that the terms of all the granite and marble, with quality make for years to come.
The needs of the simultaneous launch of all ten hydroelectric units there - both here and five of their power now work enough to serve the Sayan Aluminum Plant, and, moreover, to regulate the entire energy system of Siberia. At full capacity HPP operates mainly in the flood ...
Hydraulic №8 also runs a scheduled scan.
The ceiling height in the engine room - 25 meters, when the accident everything was filled with water up to the level of the balcony. A few people survived, holding on to the top of the beam, and a few were found in the lower areas, where he created a small airbag ...
On the left rail passes for the semi-gantry crane, two of them in the machine hall capacity of 500 tons each, they are used for hydroelectric units mounting.
The beginning of the biography of the Sayano-Shushenskoye gidroenergokompleksa can be considered as November 4, 1961 In 1964, work began the preparatory phase of construction - the construction of roads, housing, the creation of a production base. In 1968 he started dumping the right bank of the pit first. In 1970 he laid the first cubic meter of concrete, October 11, 1975 blocked the Yenisei.
hydrounits largest hydroelectric power plant in Russia were launched successively in the period from 1978 to 1985-th. By 1988, construction of the station was completed as a whole. The reservoir was first filled up to the design level in 1990. HPP was adopted in 2000. In constant operation.
Phones for operational and emergency communications. The city is not going to call, but at work and do not have to.
The amount of the active power of hydraulic unit - 620 MW. On the example of the kettle is explained this way: for a kettle srednestaticheskogo need 2 kW, respectively, while a hydraulic unit can connect 310,000 such dummies.
Exit to the balcony machine room from the tailrace.
The maximum capacity of the service spillway at normal headwater level (NPU - 539 m) is 11 700 cubic meters. m / s.
passed closer to the dam itself. Under the reinforced concrete lining thickness of 1, 5 meters in diameter penstocks are 7, 5 meters - below it seems that they are narrowed, but it is not. The height of the dam crest to about - 150 meters. And below us is still nearly a hundred meters down - concrete and water, the total height of the dam 245 meters.
Finally, we climb to the crest of the dam breaking streamers and kilometer tunnel into the mountain. The length of the ridge - 1074, 4 m, the width at the bottom - 105, 7 m, along the ridge -. 25 m in plan view it has a circular arch radius of 600 m with a central angle of 102 degrees.
The station part of the dam is located in the left bank of the river bed and consists of 21 sections of the total length of 331 to 6 m. On the side downstream to the power house is adjoined, in the zone of adjacency at around 333 m transformer arranged marketplace. The main spillway has 11 holes that are recessed 60 m from the NPU and the spillway channel 11 consisting of a closed portion and an open tray which extend downstream face of the dam (pictured right). Spillways and equipped with basic repair gates.
Great view from the ridge on the Yenisei.
The spent his life time the turbine wheel is now performs the function of the monument near the entrance.
156 tonnes of stainless steel iron! The second is the same wheel sawed and passed for recycling.
Cavitation blades after 4 years of work. Water tried ...
Let us go back to the ridge. There are now working mountaineers who perform works on cleaning the moss from the surface of the concrete wall of the dam, and inspect it for signs of surface condition of the concrete.
The stability and durability of the water dam and the pressure provided by its own weight (approximately 60%) and by transmitting the hydrostatic load on rocky shore (40%). The dam is embedded in rocky coast to a depth of 15 m. Conjugation of the dam with a base in the tie line produced to solid rock to a depth of 5 m.
The construction of the power plant took a total of 9, 7 million cubic meters of concrete. Together with the construction of spillway 10, 2. For clarity - with so much concrete you can build a two-lane highway from Moscow to Vladivostok! However, only in a straight line, but still ...
The scale is clear?
In total, the dam along the horse facets 10 arranged in longitudinal galleries that hosts about five thousand units of test equipment and cables that are derived from more than six thousand sensors mounted in the process of construction and operation. All this allows the CIA to assess the state of the structure as a whole and its individual elements.
Another climber to scale.
The catchment area of the river basin, which provides flow to the alignment of HPP, is 179 900 sq. km. Average annual flow in range of - 46, 7 cubic meters. km. The area of the reservoir is 621 sq. km, the total capacity of the reservoir - 31, 3 cu. km, including useful - 15, 3 cu. km.
spillway of the dam, built in 2005-2011, has a length of 189, 6 meters and is located at the right bank.
It seems that he's close, but in fact there is almost 3, 5 kilometers ...
To date, the station is not simply restored and completely renovated, making the most modern in Russia. We wish Hydropower successful and trouble-free operation!
