The present invention relates to a system for supplying land power to a ship and a method thereof. According to the present invention, the system comprises: a land transformation unit receiving and transforming commercial high voltage power on the land; a main power supply cable connected to the land transformation unit; a land side high voltage distribution panel including a land side vacuum circuit breaker cutting off or connecting power of the main power supply cable; a cable supply unit including a reel winding and unwinding a ship connection power supply cable and connected to the land side high voltage distribution board; a socket box installed in a ship and including a socket detachably connected to a plug disposed at an end part of the ship connection power supply cable; a low voltage distribution board connected to a main wire of the ship and including an air circuit breaker disposed therein; a ship side land power supply cable connecting the socket of the socket box with the low voltage distribution board of the ship; a ship side high voltage distribution board including a ship side vacuum circuit breaker connected to the ship side land power supply cable after the socket box to cut off or connect the power of the ship side land power supply cable; and a transformer converting power supplied through the ship side land power supply cable after the ship side high voltage distribution board. Accordingly, the system safely supplies commercial high voltage power of the land to a ship anchored at a wharf.
