description: The subject of the graduate of qualification work is Â«Modernization of the impeller of Thak-Ba HPPÂ».

The given work is devoted to the modernization of Thak Ba HPP. To modernize the existing runner, an analysis of the hydraulic turbine operation area was carried out. Based on the maximum head of 36m should have been used runner PL40, but after determining the zone of operation it was decided to compare it with the runner PL50. As a result of the comparison of their efficiency performance at different headings it was found that the use of runner PL50 will be optimal and it will be taken into further calculation.

To determine the efficiency of the runner, on the basis of the obtained CFD-anal-ysis, a strength analysis of the runner blade was carried out to determine the maximum stresses of the blade, as well as vibration analysis. Based on the results of the calculations, the runner blade was found to be serviceable.

Based on the operating area of the hydraulic turbine, values of the blade installation angles were selected. On the basis of the obtained angles the values of axial and circumferential forces and hydraulic moment of the blade were determined, on the basis of which the forces acting on the details of the runner turning mechanism were calculate.
