Station Design
The hydroelectric power station is built in a dam type with a riverbed building of a hydroelectric power station. The composition of the waterworks facilities:
- right-bank earthen bulk (gravel-sandy soil) dam with a screen of sandy-loamy soil;
- 222 m long riverbed hydropower plant combined with deep spillways. The capacity of deep spillways is 5270 m³ / s;
- mating structures - cellular abutment with retaining walls from the side of the earthen dam and retaining buttress wall from the side of the left bank;
- single-chamber single-thread navigable sluice with upper and lower approach channels;
- Outdoor switchgear 220 kV.
The capacity of the hydroelectric power station is 702 MW, the average annual output is 1.53 billion kWh . In the building of the hydroelectric power station, 6 hydraulic units with rotary vane turbines PL50-V-850 operating at a pressure of 23.5 m (impeller diameter 8.5 m) and generators SV-1436 / 200-80 UHL with a capacity of 117 MW each were installed. The manufacturer of hydroturbines is the Kharkov Turboatom plant, and the generators are the Petersburg -based Electrosila enterprise.
Pressure structures of hydroelectric power plants form a large Shulba reservoir . The reservoir area at a normal retaining level of 255 km² . The full and useful reservoir capacity is 2.37 and 1.47 km³, respectively, which allows seasonal flow control. The mark of the normal retaining level of the reservoir is 240 m above sea level (according to the Baltic altitude system ), the level of the dead volume is 232 m [1] [2] .
History of construction and operation
The design of the Shulbinskaya hydroelectric power station was started by Lengidep in 1954-58 on the basis of the “Scheme of energy use of the river. Irtysh. " Since 1965, the Hydroproject Institute has been designing the station. In 1971, an examination of the USSR State Planning Committee examined the feasibility study of the Shulba hydroelectric facility with a mark of NPU 260 m, following the results it was proposed to consider the option with a NPU of 240 m. In 1975, a revised feasibility study was issued, in which it was planned to construct the hydroelectric complex in two stages, primarily with NPU 240 m and in the second - with NPU 260 m (in this case, the capacity of the hydroelectric power station increased to 1350 MW, generation - up to 2.89 billion kWh, the useful reservoir capacity - up to 7.1 km³). In this form, the feasibility study was approved by the examination and the project was recommended for implementation [3] . Detailed design has been carried out since 1976 by the head institute, and since 1978, by its Kazakh branch. During the detailed design, some design decisions were changed, in particular, instead of a homogeneous filling dam, a bulk dam with a screen was adopted. In 1988, the Kazakh branch of the Hydroproject developed a feasibility study for the construction of the second stage of the Shulba hydroelectric complex, which substantiated the second-stage NPU at the level of 255 m, at which the capacity of the hydroelectric power station increased to 1050 MW, generation to 2.32 billion kWh, and the useful reservoir capacity is up to 6.16 km³ [4] .
The construction of the hydroelectric power station was started in 1976, the launch of the first hydroelectric unit took place on December 23, 1987, the last hydroelectric unit was launched on December 19, 1994. The design of the station provides for the construction of the second stage, while increasing the height of the earthen dam and the building of the hydroelectric power station, as well as reconstructing generators (replacing the stator winding and poles). In the 2000s, the completion of the waterworks was carried out, in particular, in the spring of 2005, the shipping lock was put into continuous operation. In 1997-2017, the hydroelectric power station was in the concession of AES . As of 2018, the issue of the construction of the second phase of the Shulba HPP has not been resolved.
Below the Shulba hydroelectric station, it is planned to build its counter-regulator - the Bulak hydroelectric station , which will allow more efficient use of the hydroelectric potential.
