Power Machines manufactured and started the shipping of a hydrogenerator intended for the upgrade of the hydropowerunit No. 5 at Rybinskaya HPP.
The 65 MW generator was manufactured under the contract for the replacement of three power units of the Rybinskaya HPP, signed between Power Machines and RusHydro in 2015. The scope of obligations of "Power machines" included development, manufacture and supply of equipment for hydro turbines, hydro generators and auxiliary systems of hydropower units, as well as their installation, testing and commissioning.
The new equipment of Power Machines has got improved technical and power characteristics and is also more reliable. The company's designers used modern and innovative design methods in their work, which would increase capacity of each hydraulic turbine by 18% - from 55 MW to 65 MW. In addition, the impellers have an environmentally friendly design with oil-free bushings that prevent oil from entering the water.
Hydropower units No. 1 and No. 3 updated by "Power machines", were successfully commissioned in March 2018 and August 2020 respectively, after which the HPP power increased by 20 MW.
Currently, the work is underway to replace equipment at the power unit No.5, which is scheduled to start up in 2021. As a result of the project, the capacity of the Rybinskaya HPP will increase by 30 MW.
