Miatlinskaya HPP

• Miatlinskaya HPP

Miatlinsky power plant - the second (middle) stage of the cascade hydropower stations on the river Sulak Kizilyurtovsky district of Dagestan. We went up the river Sulak River into the station, from which the water reservoir of Makhachkala.

At first, our eyes opened view of the bottom construction of the station - is the main powerhouse, outdoor switchgear and surge tank. Dam itself was hidden in the valley. November sun entangled in the clouds and not warmed. I heard the sound of water and a slight buzzing ORU. Romance.

The machine room. The building set HPP 2 Kaplan hydroelectric power of 110 MW rated operating at a head of 46 meters. Miatlinskaya HPP serves as a counter-regulator powerful Chirkeyskaya HPP (upper stage of the cascade total), leveling uneven diurnal water consumption in the interests of agriculture, fisheries and communal services, while avoiding idle discharges.

We go down to the hydroelectric units.

A bit of history. In 1970, the preparatory works for the construction of hydropower plants were started. In 1977, on the right side there was a large landslide, with the result that the construction was stopped. The deadlines have to perform large-scale landslide work, change the design decisions and change the scheme waterworks.

As a result, the power house has been moved to the 1, 5 km. Already in 1982 in the dam body of the first cubic meter of concrete was laid, and the installation of the first unit was launched in 1985. By 1986, it was put into operation two hydraulic unit.

All of us in the apartments are equipped with siphons. This vodouravnitelny tank can also be called a siphon, but it is slightly different sizes. The main objective of this design - to avoid water hammer in the hydroelectric system.

If you need to stop the station or some urgent dropping gates, the water will not harm the structures, tunnels, gates, building hydropower plants. It simply goes into the siphon. If you need to - and will come out of it for a few seconds fountain (but this is from the realm of fantasy rather).

In one and a half kilometers away in the valley is arch dam. You can reach it only swim or wade through the mountain.

Select the second option - Road tunnel length of 600 meters, connecting the building of hydroelectric dam.

Miatlinskaya HPP

Meet - concrete arch dam height 86, 5 meters. It's like a 28-storey building. along the crest length - 179 meters (almost like two football fields). In the downstream of the water it is very small, because at this time of year all the flow passes through the hydraulic units, and idler (flood) water discharge closed.

The stark beauty.

In the cockpit of the gantry crane on the crest of the dam. It is worth noting that our gang of photographers jumped on the dam is not worse than the mountain goats. We crawled all you can. Apparently fresh air acts as energy to us.

Center. Top standard rain water flowed from the reservoir.

We are getting soaked. But it was more flowers ...

Reservoir Miatlinskaya GES - 47 million cubic meters, which is not too much.. Panorama shot with a gantry crane, which controls the gates of the diversion tunnel, culvert, coming to the building of hydroelectric power station through the rocks.

Water Sulak. She turquoise and the greater its depth - the more it gives cyan. For people who did not see it live, it seems dabbling with photoshop. Yet it is a valid color. That color the water can be found on so many mountain rivers fed by glaciers. Turquoise water allow suspended particles of blue clay. That's all the explanation.

Then we went for a walk in the dam body.

Somewhere walked, rolled, rose and fell.

Another point. Echo there is good ...

And here is the beginning of the work of idle spillway. Gantry crane just a few centimeters lifted multi-ton metal gate, and there was 70-meter waterfall.

poured down water from the sky ...

Miatlinskaya HPP

A lot of water. And without that cold November morning ferry filled with ice.

Miatlinskaya HPP

Cameras began to quickly get wet, but continued to work, but the hands are reluctant to keep the equipment and press the buttons. I had to work his nose.

Miatlinskaya HPP

In order to have time to remove the water discharge from several angles, we rushed up and down the dam, and then slipping on the treacherous ice.

Not feeling breathing and cold, we race soared on the crest of the dam. View from the gantry crane.

After these forces runs completely gone. For the final panorama had to get a helicopter.
