Mainskaya HPP trout farm and Yenisei

Mainskaya HPP - the younger sister of the power plant, which is 21 kilometers downstream of the Yenisei. Both stations are a single hydroelectric complex, technologically closely related: Mainskaya - kontrreguliruyuschaya station Sayano-Shushenskaya - peak. On the technical level, this complex is unique in Russia.

1. In the course of the year, and during the day electricity needs are different, so the peak hydroelectric SSHHPP (pictured) promptly reacts to these fluctuations. This leads to a permanent change in the level of the river downstream and causes inconvenience to the water user communities located downstream of the Yenisei.





2. In order to solve this problem was built Mainskaya HPP. Its main task (except for power generation) - smooth out the fluctuations in the level of the river after the Sayano-Shushenskaya HPP. Compared with the older CETP Mainskaya station it seems baby.



3. The height of the spillway of the dam of 34 meters.



4. The total length of the ridge about 750 meters, and in contrast to the Sayano-Shushenskaya HPP, the dam station organized a free car passage across the Yenisei.

6. The engine powerhouse has 3 Kaplan hydro unit capacity of 107 MW.

10. Water turbines HPP was unsuccessful designed and could not work in Kaplan mode, resulting blades were zafiksirovanny at a certain angle, which greatly reduced the efficiency of hydroelectric power plants.



11. In 2006, one of the impeller hydraulic units were replaced, thus increasing plant production. It is planned to replace impellers remaining hydraulic units, and construction of another power house with two hydraulic units, which will significantly increase the capacity of the plant.

19. Here is the trout farm. After the accident at the Sayano-Shushenskaya HPP killed a lot of fish because of the saturation of water with oxygen.
