Power Machines have shipped another batch of large equipment for the power plant

"Power Machines" has carried out a third party shipping large equipment manufactured by the company and designed to restore the Sayano-Shushenskaya hydroelectric power station (SShGES). 

Heavy units for Sayano-Shushenskaya HPP hydro units were loaded on the ship, "Arsenal" on the dock at the Sverdlovsk waterfront in St. Petersburg. Transportation of large equipment, which consists of three rotor wheel (the weight of each wheel — 145 tons, diameter — 6.84 m), two axial bearings of maslovann (weight of each — 21 tons, diameter — 6.1 m) and two 13-ton cores auxiliary generator rotor diameters of 6.09 m each, will be made only possible way — by sea and river routes in the summer navigation. After receiving all the necessary permits ship will leave St. Petersburg. Delivery of the new equipment will last 35 — 40 days.


Loaded on a ship with his ponderous hydroelectric units will pass through Ladoga and Onega lakes. Then, through the White Sea-Baltic Canal, will be released in the White Sea, and more — on the Northern Sea Route to the mouth of the Yenisei. Then the ship will proceed up the Yenisei to Krasnoyarsk. In Krasnoyarsk river port equipment will be handled on a river barge, which, breaking the ship lift Krasnoyarsk hydroelectric power station, with a river tug will deliver the goods to the dock site in the downstream Mainskaya power plant (located downstream of Yenisei 21.5 km from SShGES). This equipment will be handled by a special vehicle that takes hydroelectric units at the Sayano-Shushenskaya HPP. The total route length of about 5900 km. More detailed information on the whereabouts of the ship and the details of the transport operation to deliver the new equipment is available on the website of JSC "RusHydro" — "Sayano-Shushenskaya HPP. PSNeporozhny" at: http://www.sshges.rushydro.ru/press/tracing/.


Last year a similar way from St. Petersburg to the station were delivered six sets of large equipment made "Power Machines" for SShGES. Delivery of the last batch of large-sized equipment is scheduled for August of this year. At the request of JSC "RusHydro", "Power machines" carry out the order for the production of equipment for the recovery SSHHPP ahead of production schedule to meet the deadline navigation in 2012. So, ahead of manufactured generating equipment and impellers. To date, the "Power Machines" manufactured and shipped to the Sayano-Shushenskaya HPP hydro eight and seven turbines. Production of the remaining equipment is scheduled for completion by the end of 2012.

In 2010, at the Sayan-Shushenskaya HPP least affected were restored after crash hydraulic units with station № 6,5,4 and 3. In 2011 JSC "RusHydro" the beginning of the second stage of recovery HPP, during which the station in the engine room will be set 10 all-new hydraulic units. In this case, four cars returned to service in 2010 after the restoration repairs, will also be replaced. 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. Also in mid-June of the current year have been successfully completed a 72 hour comprehensive commissioning test of the new third hydraulic unit (under the station number 8).  

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 contract is worth 11.7 billion rubles (without VAT). 

The service life of new hydroelectric will be increased to 40 years, with a maximum turbine efficiency 96.6%. Will improve its energy and cavitation characteristics. Also, the turbine will be 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.
