 At small and microHPPs low-pressure turbines of various designs are used. The widest application received the following:

  • active turbines with the tangential supply of a high-speed stream to the driving wheel, equipped with blades of a special form. In active turbines kinetic energy of the stream is almost completely used;
  • reactive turbines with the axial supply of water to the driving wheel blades. Driving wheel rotation occurs due to drawoff of a pressure drop between the turbine inlet and outlet.
