"Power Machines" manufactured and carried out the last shipment of equipment hydro-generator, designed to restore the Sayano-Shushenskaya hydroelectric power station (SShGES).
In addition to the new hydro produced to date "Power Machines" manufactured and shipped to the Sayano-Shushenskaya HPP hydro eight sets of equipment. Production of the two remaining sets will be completed before the end of 2012. Shipped to all large equipment for hydraulic units (impellers turbines, generators maslovanny thrust bearings, rotor cores auxiliary generators).
In 2010, at the Sayan-Shushenskaya HPP least affected were restored after crash hydraulic units with station № 6,5,4 and 3. Remanufactured hydraulic power units operating in basic mode without participating in the regulation of frequency and power.
In 2011 JSC "RusHydro" the beginning of the second stage of recovery HPP, during which the station in the engine room will be installed 10 brand new hydraulic units. In this case, four cars returned to service in 2010 after the restoration repairs, will also be replaced. This has already withdrawn from work for replacement of hydraulic power units with station numbers 5 and 6.
The first new hydraulic unit (under the station number 1) in accordance with the schedule recovery SSHHPP was commissioned in December 2011, the second (under the station number 7) — in March 2012, in June of this year was put into operation at the new hydraulic unit (under the station number 8). Before the year is planned to put into operation a hydroelectric station number 9.
Annually by 2014 SSHHPP in accordance with the schedule of recovery will be commissioned on three hydroelectric. As a result, the station will be fully equipped with a completely new and modern equipment, with improved performance and compliance with all safety and security requirements.
The contract for the manufacture of main power equipment to restore the Sayano-Shushenskaya hydroelectric power station "Power Machines" and JSC "RusHydro", signed in November 2009. According to him, "Power machines" produce 10 turbines and nine hydro generators with a capacity of 640 MW, as well as six excitation systems. In addition, the specialists of "Power Machines" will provide services for installation of the supplied equipment, including installation supervision and commissioning.
The service life of new hydroelectric increased to 40 years, with a maximum turbine efficiency of 96.6%. Improved its energy and cavitation characteristics. Also turbines are equipped with a more efficient system of technological protections acting on the automatic shutdown of the unit in case of unacceptable deviations regime controlled parameters.
