Near hydroelectrostation 3 installed backup heat engine 4 to a generator. The electric current produced by the generators through the transformer 5 is fed into the grid.Installation for converting sea wave energy into electrical works as follows. Rolling waves of the sea (ocean) put pressure on the deflector 6, located above the calm sea, which rotate and overlap, forming a solid wall, allowing the progressive wave energy results in rotational movement of the blades installed, the blade sinking into the water, under the action of water resistance rotated parallel to the direction of rotation, which dramatically reduces the resistance of the lower blades passing through the water column, which increases the efficiency of the installation. Blade shaft 4 rotates, it transmits the motion to the pump 7, which increases the pressure of the water entering the pump 7, and transmits pressurized water through the collector pipe 10 in hidroelectrostroy, the rotor of which is connected to a generator that converts the rotational moment of hidroelectrostroy into electricity. Installation for preobrazovanijj each of which is arranged protruding above the calm sea, characterized in that the shaft is located below the level of wave generation and is connected with the hydraulic pump, through which the pipeline is connected with hydroelectrostation, and the working part of the blade is made in the form of rotatable louvers, protruding above the calm sea at 2/3 of its height and mounted on the rack.
