A shaft generator system feeds sufficient power to the electric apparatus in a ship by using a part of the power produced by the main engine. Conventional type of such system has a drawback of involving a large amount of harmonics in the output voltage waveform. A novel and simple shaft generator system without output voltage distortion is presented here. The proposed system is equipped with a duplex reactor to cancel out the subtransient inductance of the synchronous compensator. The steady-state characteristics of the system are then discussed, and it is shown that when the duplex reactor is used, the inverter dc input voltage and synchronous condenser terminal voltage should be increased for a larger system output to keep the output terminal voltage constant. A simple method of suppressing the increase in these voltages is also proposed. The effectiveness of the proposed system was confirmed with the experimental investigations.
