CONSTITUTION: A power generation system for a ship comprises a reduction gear(20), a shaft generator(40), and a frequency-variable drive(50). The reduction gear is connected to a main engine(10), controls the speed of a rotary shaft of the main engine, and provides the controlled speed to a pitch-controllable propeller(30). The shaft generator is connected to the reduction gear and generates electricity when the main engine operates. The frequency-variable drive is connected to the shaft generator and controls frequency and voltage when the main engine operates with variable RPM.
