Hydropower In The Face
In the Cheboxar GPP, Rusgidro commissioned reconstructed hydroagate (GA) No. 2. Competitive machine specialists have re-established the hydroturbine turning-loss mode and produced a new hydrogenerator hertor.
The lag of the reconstructed working wheel changes the angle according to load and pressure, which increases the efficiency of the hydroagate. At present, 8 of the 18 hydroturbine stations have been transferred to a turning-loss mode. In addition, the Cheboxar GEC hydroturbines have an environmentally sound structure with no oil-free working wheels. This prevents even the hypothetical possibility of oil entering water.
The extensive work on GA No. 2 under the Integrated Modernization Programme (PCM) Rous Gedro began in January 2014. Last June, during the transport of the working wheel hull from the hydro station, a photo report was made to the manufacturer for the Ludy Light Project * - Second Youth of the Cheboxar GEC.
Hydroaggregate No. 2 was the first in the Cheboxar GEC to replace a hydrogenerator statator. The reconstruction will extend the life of the generator and improve its performance.
In addition, three more hydroagata of the Cheboxar GEC are currently undergoing various stages of modernization. The GAS No. 13 hydropower turbines were already sent to the manufacturer for the re-establishment of the reversing mode. On the same hydroagate, an old generator's cathedral is being dismantled. The renovated " Silk Cars " , hydroturbine No. 10, currently collects at the station ' s mounting site specialists from the subsidiary company Rusgidro - AO " Gedroremont-WCC " under the supervision of the manufacturer ' s chief engineer. And the GAS 10 itself is collecting a new generator pack. The hydro aggregate with station number 5 is also being processed to renovate the turbine and replace the hertor.
By 2025, Rus Gidro plans to transfer all the Cheboxard GEC turbines to a turning-loss mode and to establish new statues on all hydrogeners.
Integrated upgrades are aimed at improving the safety and reliability of hydropower equipment, reducing repair and maintenance costs. The annual renovation schedule is agreed with the Single Electricity System operator and does not limit the electricity supply to consumers.
