A shaft generator system supplies electrical power required in a ship by using a part of the power produced by the main engine. Since the speed of the main engine can vary over a wide range, an externally commutated thyristor inverter, which has high reliability, is generally used to produce ac power with constant voltage and frequency.<br>In this paper, a set of system equations, by which the total harmonic distortion of the output voltage, for example, can be estimated, is derived first. The effects of leading angle of the inverter and the reactance of ac reactor located in the output-side of the inverter on the system performances and the operation limit of the system are then clarified. Moreover, a way of taking the system losses into account is proposed to obtain precise calculation results. Finally, the apparent power for the synchronous condenser to provide reactive power in the system is discussed.
