Dagestan - Chirjurtsky hydroelectric (50 photos)

In the central mountains of Dagestan at the confluence of the Avar and Andean Coys formed rough and rapid river Sulak. This is one of the major river systems of Dagestan with a total length of 144 km. In 1954 Kizilyurt district "SulakGESstroy" USSR Ministry of Energy launched the preparatory work for the construction of the first hydroelectric power station on the river. Already in December 1955 the first bridge was built on the river. Sulak, started the development of pits and soil, and in 1958 completed the construction of the power house and the entire set of facilities engaged in water supply and drainage to the station site HPP. Then began the construction of dam, and in March 1959 the river Sulak was blocked.



December 22 this year will be exactly 50 years from the date of commissioning Chirjurtsky HPP-1. In that distant day in 1961 the launch of the station carried out a duty engineer Zubair Magomedov, who later during the 37 years he headed Chiryurtionskaya HPP Cascade.

The complex consists of 3 Chiryurtionskaya hydroelectric power stations: Chirjurtsky HPP-1, HPP-2 Chirjurtsky and Gelbakhskaya GES (GES-3 Chirjurtsky). The complex is the bottom step of the cascade Sulak.

Getting to the station, we start with the master plan, which was developed by the Baku branch of "Hydroproject". For 50 years, of course, a lot has changed, but the basic structures are the same.



Nearby is a museum where you can see models of GES, as well as various historical photos and documents. In the picture - a fragment layout construction Gergebilskaya HPP.



A bit of historical photographs from the museum HPP. Installation of hydraulic units.



Construction of the power plant building.



Our visit started with the station control room. Now, on the eve of the anniversary, the building is on the cosmetic repair, so everything inside is forced by forests. Undergo mandatory safety training.



Gamzat Isakov can safely be called hereditary crane. Starting work in Sulakskaya coordinated hydroelectric slinger in 1995, now it is the engineer of bridge and gantry cranes. His father also worked as a crane operator in the company KaspiySGEM.



The building has 2 hydroelectric Kaplan hydroelectric capacity of 36 MW operating under a head of your payable 42 5 m.



In the near future we will begin a comprehensive program of modernization of the station.



The engine room Chirjurtsky HPP-1 is an overhead crane lifting capacity of 150/30 t (two hook: 150 t - the main lift and 30 tons - a subsidiary) for equipment maintenance machine room - namely the transfer of heavy parts of hydraulic unit to the installation site during repair .



The aesthetic beauty of the old equipment.



GES has played a major role in the development of the industry of Dagestan.



We go down into the maze of technical facilities.



Shaft connecting the impeller and the generator. It has a length of 3, 6 meter diameter - 0 6 meter and is rotated at 187 revolutions per minute.



In these tubes is turbine oil.





The most valuable thing in the stations - it is the people who work there and who we met and organized the trip. Thank you very much for an interesting experience!

Power house and switchyard (Open switchgear).



Hydroelectric dams, built by derivation scheme.



ORU.



These cables stretched especially for hydro measurement performed at the time commissioned some research organization. In a cable to hang special equipment, which went down into the water and took the testimony, which, in turn, determines the flow rate of water through the turbines.



Metal penstocks diameter of 5, 4 meters. On the right is gryazespusk.

Modern look. On the pipes in the bottom left corner you can see the connection contraption - a telescopic joint, which compensates for thermal expansion of water lines.



The locking mechanism on the gantry crane, which stands on the station and pressure unit.



Water is supplied to the node on derivational channel length of 3458 m, a width at the bottom - and a depth of 7 m - 8, 8 m, calculated on consumption of 200 cubic meters / sec.

On the offtake channel of HPP-1 is the second station, which has its own name - "Pioneer of Dagestan».



There are two legends, why Pioneer:

From the book Shahrudina Shamkhalova "Dagestan: My Love and Destiny", Chapter 6, "How to start a stage." (Makhachkala, Dagestan Publishing, 1998):

"During the construction of hydropower plants on the initiative Chiryurtovskaya builders took another parallel in a single hydroelectric station -" Pioneer of Dagestan ". Interestingly, as the pioneers of the "trial" for her unit. The equipment for small hydro power plants were not issued, but we sent a group of pioneers and Komsomol in Ukraine, where they visited the Kharkov plant electric turbines and persuaded Komsomol plant gathering for Dagestan unique units. Soon, a telegram arrived from Kharkov, indicating the value of the units and the need to confirm the agreement. I gave the order to transfer the money. So to address the issue of building another hydroelectric power station - "satellite" Chiryurtovskaya HPP. All the young enthusiasts were encouraged and sent to the best camping sites of the country ».

The second legend is told by station staff, it is that the scrap metal collected by the pioneers, was used for the manufacture of the hydraulic unit.

Now the station is being repaired - is the current repairs of the hydraulic and the concrete lining of tailrace.



Underwater tailrace structures that are not normally visible.



Hydroelectric power - 9 MW. The building has a single Kaplan hydraulic unit, operating at a head of your payable 7m. On it you can see the number "3" - a common numbering with HPP-1.



In late 2008, hydropower was held extensive repairs. In particular, it has been replaced by a stator of hydraulic generator and excitation system, and change the shape of the suction tube.



Depth, cleaned and repaired exhaust channel, which led to an increase in operating capacity of 2 MW hydropower plant.



Oh, what pokazometry.





Some pokazometry again. They are there a lot.

And it's kind of small hydroelectric power station! And what is the scale! By the way, there's an interesting spillway applied - the side, combined with the building of hydroelectric power station.



Strange dome at the top. As it turned out, because of the small power house all repairs carried out on the street: that's hauled units covered by these tents, and all the work is done inside.



Gantry crane and transformer stations.
