The present invention relates to a power supply system for a drone for education or practice, and is to directly supply battery power and commercial power by connecting a power supply device following a flight path of a drone to an educational or training drone. To this end, the present invention repeatedly flies along a drone flight path including a takeoff/landing point and a hovering point at which the drone takes off or lands at a drone aerodrome including any one of an education field, a practice field, or a permanent test site, or repeatedly performs the same operation. In the power supply system for drones for education or practice, including a drone-following power supply device that directly supplies power and control signals to the in-flight drone by following the location of the drone in flight along the drone flight path within the drone aerodrome. It is possible to extend the battery usage time of drones for education or practice, shorten the life of the battery and prevent frequent replacement.
