RusHydro and Power Machines have announced they have completed the overhaul of another hydropower unit at Cheboksarskaya hydroelectric project, with Hydropower Unit 13 featuring an upgraded adjustable-blade impeller and a new hydrogenerator stator manufactured by Power Machines.
The overhaul allowed for adjusting the angle of the hydroturbine blades depending on the water flow and water pressure, improving unit performance. So far 10 of 18 turbines are operating in the adjustable-blade mode.
Hydropower Unit 13 is the third machine at the plant to feature a modernised impeller and a new generator stator. Another two stators were replaced in 2014-2015 at Hydropower Units 2 and 10. Smilar works are planned for the remaining hydropower units.
