Disclosed are an automatic power factor compensation system and method for a ship using a shaft generator, which may enhance the convenience and safety of the operation of the ship. The automatic power factor compensation system for a ship using a shaft generator according to the present invention comprises: a main engine which generates propulsion power of a ship; a generator engine which produces electricity required in the ship; a shaft generator which performs generation by using a rotational force of a shaft that transmits power of the main engine to a propeller; and a shaft generator drive which converts the electricity produced by the shaft generator into a fixed frequency and then supplies the same to an electrical power system of the ship. The shaft generator drive is connected to the generator engine and is operated in a power factor compensation mode that compensates for reactive power when the shaft generator cannot be operated for electricity production.

    축발전기를 활용한 선박의 자동 역률 보상 시스템 및 방법이 개시된다. 본 발명에 따른 축발전기를 활용한 선박의 자동 역률 보상 시스템은, 선박의 추진 동력을 발생시키는 메인엔진; 선박 내에 필요한 전력을 생산하는 발전기엔진; 메인엔진의 동력을 프로펠러로 전달하는 샤프트의 회전력을 이용하여 발전하는 축발전기; 및 축발전기에 의해 생산된 전력을 고정 주파수로 변환하여 선박의 전력 계통에 공급하기 위한 축발전기드라이브;를 포함하고, 축발전기드라이브는 발전기엔진과 연결되어 축발전기가 전력 생산을 위해 가동될 수 없을 시 발전기엔진의 무효전력을 보상하는 역률 보상(Power Factor Compensation) 모드로 운전되는 것을 특징으로 한다.
