The use of turbogenerator units with a variable rotational speed is the leading world tendency to which due attention is not being devoted in our country. The expediency of replacing the operating adjustable-blade turbines that have exhausted their standard service life by propeller turbines of the same type with a variable rotational speed is shown for the example of the Maina HPP. Substantiation of the angle of setting the blades of the propeller runner and an evaluation of the energy effects obtained are given.
