SUBSTANCE: invention relates to alternative sources of power, in particular, to tidal power plants. The method consists in the fact that a part of basin water area closed by a dam at the side of the sea, with a river flowing into it, exit of which into the sea is via hinged or pontoon gates only during ebb, together with the river bed from its mouth and to the dam is cut with the dam designed to create upper reach at the side of the river bed. The difference is discharged into lower reach via water conduits adjusted in the dam, to which submerged power units are connected. On the way of the river bed displaced by the dam to one of basin coasts, they install hinged or pontoon gates providing for only single-sided passage of a tidal wave into the water area of upper reach, providing for level difference necessary for turbines operation regardless of change in tide phases.

EFFECT: increased efficiency of power plant operation with lower costs and less time.

SUBSTANCE: main and auxiliary vertical double blades are arranged on a turning cantilever. The axis of the main blade in a central part is connected to a casing on the cantilever end with a return spring, and its planes are fixed asymmetrically on the axis, i.e. with a larger surface area towards the cantilever attachment centre.
