Power Machines has produced the hydraulic turbine impeller for unit No. 3 of the Rybinskaya hydropower plant in Russia, with delivery of the impeller scheduled for this month.
The equipment was manufactured under a contract awarded by RusHydro which covered the replacement of three units at Rybinskaya in 2015. Thanks to the new equipment, the capacity of each turbine is being increased by 10MW. In addition, the impellers have an environmentally safe design with oil-free bushings, which eliminates the possibility of oil entering the water.
Power machines obligations under the contract included: development, manufacture and supply of equipment for hydraulic turbines, hydro generators and auxiliary systems of hydraulic units, as well as their installation, testing and commissioning.
The first of the three updated hydraulic units was put into operation in March 2018. Currently, Power Machines is working on the replacement of No. 3, the launch of which is scheduled for the end of this year. Unit No. 5 will be the last to be replaced, with the project to be completed in September 2021.
