The present invention relates to a smart grid power control system for an electric propulsion ship comprising: an electricity management terminal formed on a generator in an electric propulsion ship to control and monitor an electricity generation amount; a propulsion load management terminal formed on a propulsion load terminal of the electric propulsion ship to control and monitor propulsion load consumption electricity consumed in propulsion power; a non-propulsion load management terminal installed on a non-propulsion load terminal of the electric propulsion ship to control and monitor consumed non-propulsion load consumption electricity other than propulsion power; and a control unit connected to the electricity management terminal, the propulsion load management terminal, and the non-propulsion load management terminal to monitor electricity generation amount and consumption amount information in the ship and transfer a control signal for changing and controlling an electricity amount transferred to the non-propulsion load to the propulsion load management terminal and the non-propulsion load management terminal to maintain electricity consumption of the propulsion load terminal in a preset normal state. According to the present invention, in an electric propulsion ship, electric energy is distributed to a propulsion load of the ship in the highest priority to guarantee the sailing stability of the ship.

    본 발명은 전기추진선박용 스마트그리드 전력제어시스템에 관한 것으로서, 전기추진선박 내에서 발전기에 형성되어 전기 발전량을 제어 및 모니터링 하는 전력관리단과; 상기 전기추진선박의 추진부하단에 형성되어 추진동력에 소비되는 추진부하 소비전력을 제어 및 모니터링하는 추진부하 관리단과; 상기 전기추진선박에서 비추진 부하단에 형성되어 추진동력 이외에 소비되는 비추진부하 소비전력을 제어 및 모니터링하는 비추진부하 관리단과; 상기 전력관리단과 추진부하 관리단, 비추진부하 관리단과 연결되어 선박 내 전기 발전량과 소비량 정보를 모니터링하며, 상기 추진부하단의 전력 소비가 미리 설정된 '정상상태'로 유지되도록, 상기 비추진부하에 전달되는 전력량을 가변 제어시키는 제어신호를 상기 추진부하 관리단과 비추진부하 관리단에 전달시키는 제어부로; 구성되는 것을 특징으로 한다. 본 발명에 의하여 전기추진선박에 있어서 선박의 추진부하에 가장 우선적으로 전기 에너지가 배분되게 하여, 선박의 운행 안정성을 보장하는 전기추진선박용 스마트그리드 전력제어시스템이 제공되는 이점이 있다.
