The present invention relates to a device for learning the principle of power generation, and more particularly, a housing having an inlet hole communicating with an inner space on an outer circumferential surface at regular intervals, a rotating shaft fixed to the inside of the housing, and a predetermined interval on an outer circumferential surface of the rotating shaft. A rotating part including a rotating blade formed as; A high pressure air generator for supplying high pressure air to the inlet hole of the housing to rotate the rotary blades; A power generation unit connected to the rotation shaft of the rotation unit to generate power by the rotational movement of the rotation shaft; And a power generation confirmation unit electrically connected to the power generation unit to convert electric energy into other energy to check generation of electricity through the sensory organs of the body.;The present invention configured as described above has the effect of allowing the learners to directly check the power generation principle to generate the electric energy using the wind, hydropower or high temperature, high pressure steam to facilitate the understanding.;Rotating part, high pressure air generating part, power generation part, power generation confirmation part
