Claims (1)

Ковшовая бесплотинная ГЭС, включающая деривационный канал, выполненный с уклоном своего дна меньшим уклона дна реки в месте установки ГЭС, активную турбину, по ободу рабочего колеса которой жестко закреплены лопатки, выполненные в виде ковшей специальной формы, спиральной камеры для подвода водотока деривационного канала к рабочему колесу турбины и механизма редуцирования числа оборотов колеса турбины к оборотам генератора, отличающаяся тем, что в механизме редуцирования числа оборотов колеса активной турбины к оборотам генератора установлен механизм искусственного торможения вала генератора, выполненный, например, в виде управляемой гидродинамической муфты, тормозной момент которой равен тормозному моменту генератора при его полной электрической загрузки и изменение которого обратно пропорционально ей, так что моменты обеих механизмов, генератора и механизма торможения складываясь передают валу активной турбины всегда один и тот же, по величине, тормозной момент, не зависимый от электрической нагрузки на генератор, обеспечивая постоянство вращения его ротора.A bucketless damless hydroelectric power station, including a derivation channel made with a slope of its bottom less than the slope of the river bottom at the site of the hydroelectric power station installation, an active turbine with blades rigidly fixed along the rim of the impeller, made in the form of buckets of a special shape, a spiral chamber for supplying a derivative channel water channel to the working the turbine wheel and the mechanism for reducing the number of revolutions of the turbine wheel to the generator speed, characterized in that in the mechanism for reducing the number of revolutions of the wheel of the active turbine to the generator speed The mechanism of artificial braking of the generator shaft is implemented, made, for example, in the form of a controlled hydrodynamic coupling, the braking torque of which is equal to the braking moment of the generator when it is fully electrically loaded and the change of which is inversely proportional to it, so that the moments of both mechanisms, the generator and the braking mechanism folding are transmitted to the active shaft turbines are always the same, in magnitude, braking torque, independent of the electric load on the generator, ensuring the constant rotation of its rotor.
