The dam Studen Kladenets is a dam with hydroelectric plant in Kardzhali Province , Bulgaria . It dams the Arda into a reservoir. The associated power plant has an installed capacity of 82 MW .
The facility is owned by Nazionalna elektritscheska kompanija EAD (NEK EAD) and is also operated by NEK EAD.
Barrier structure
The shut-off is a gravity dam of concrete m with a height of 67.5. The length of the top of the wall is 338 m.
Reservoir
When the reservoir is fully blocked, it extends over an area of around 28 km² and holds 338 million m³ of water. The reservoir is used to generate electricity as well as for irrigation.
power plant
The power plant is located about 500 m downstream of the dam on the right bank of the Arda. It has an installed capacity of 82 MW and went into operation in 1958. The 5 Francis turbines of the power plant each have a maximum output of 16 MW.
When it was built, four machines were originally installed in the power plant's machine house. From 2007 to 2009 the power plant was expanded by a fifth machine. The additional turbine also has an output of 16 MW (maximum 19.75 MW) and the associated generator 23 MVA . The nominal speed of the turbine is 300 rpm. The drop height is 57.5 m and the volume of water used is 30 m³ / s. The nominal voltage of the generator is 10.5 kV . In the switchgear , the generator voltage of 10.5 kV is increased to 110 kV using power transformers.
