The electric power generation system and Potential energy storage device for a power generation system

Abstract

An electric power generation system according to one embodiment is characterized by converting, and storing as potential energy, renewable energy such as wind power and wave power, and thereafter driving an electric power generation device with the released energy. Specifically, a storage device 3 of an electric power generation system 1 is provided with a plurality of sets of weights 30 and pulleys 36, and a wire 37 is hung on the pulleys 36. When the renewable energy rotates a winder 35 in a winding direction, potential energy is stored according to the weight of the weights 30 and the rising distance of the weights 30. When the winder 35 becomes rotatable in a direction opposite to the winding direction, the stored potential energy is released, becomes continuous power according to gravity and acceleration of the weights 30, and turns a generator connected to the winder 35. According to the present invention, a large amount of power can be obtained for stably driving the electric power generation device, even in an unstable and intermittent renewable energy environment.
