The renewed hydraulic unit with the station number 19 is already the 21st one, on which the turbine has been replaced, and the 14th one, on which the generator has been replaced. In accordance with the upgrade project, Power Machines performed work on replacing the turbine, generator, excitation system, automation system and auxiliary equipment.
The new turbine has an improved design and is characterized by a high degree of environmental safety. The updated impeller has five blades instead of the previous six and is designed for increased water flow through the turbine. Improved technical specifications of the unit allow increasing its capacity by 10.5 MW in the future.
Today, at Volzhskaya HPP Power Machines continues modernization of hydroelectric units No. 10 (replacement of turbine and generator) and No. 19 (replacement of generator). The program of joint plant modernization provides for the complete upgrading of hydraulic units, after which the capacity of Volzhskaya HPP will be increased to 2744.5 MW.
In total, 23 hydropower units are installed at the Volzhskaya hydroelectric station. Their upgrade is carried out within RusHydro's comprehensive upgrading program.
