A power plant comprises at least one turbine (5) driven by a variable medium flow and an electric generator (4) driven by the turbine and the induced voltage of which being an unambiguous function of the number of revolutions of the turbine. The plant has also first members (12) for detecting the electric power generated by the generator, second members (11) for detecting the voltage on the output of the generator, means (10) adapted to compare the values detected for said power and voltage with an ideal relation predetermined for the generator between these two quantities and an arrangement (10) adapted to regulate the induced voltage of the generator and thereby the number of revolutions of the turbine so that said ideal relation between power and voltage is obtained.
