A shaft generator system supplies electrical power required in a ship by using a part of the power produced by the main engine. In this report, a set of system equations, by which the total harmonic distorition of the output voltage, for example, can be estimated, is derived first. The effects of various parameters on the system performances and the operation limit of the system are then clarified. It has been shown that when the leading angle of the inverter is large, the operating range of the system is widened. Moreover, a way of taking the system losses into account is proposed to obtain precise calculation results. The apparent power for the synchronous condenser of the system is then discussed. Also, transient performance of he shaft generator system is analyzed in detail. A set of transient equations of the system is derived, and the transient responses of the system in the case of a step-up change in the dc input voltage are calculated and compared with experimental ones. Transient responses in the case of step change in the system load are also investigated. Finally, transient performance analysis of the shaft generator system is presented for the case with a load of an induction motor. A simple transient model for the motor is introduced first. This motor model is united with the transient model for the shaft generator system. Transient responses when the induction motor is connected to the output terminals of the shaft generator are simulated with this block diagram. The simulated responses are compared with the experimental responses with the tested system, and the usefulness of the theory is confirmed. Also, the effects of the inertia moments of the synchronous condenser in the shaft generator system and the induction motor on the transient performances of the system are studied.

轴发电机系统通过使用主机产生的部分电力来提供船舶所需的电力。在本报告中，首先推导了一组系统方程，利用该方程可以估计输出电压的总谐波偏差。阐明了各种参数对系统性能的影响以及系统的运行极限。结果表明，当逆变器的超前角较大时，系统的工作范围较宽。此外，还提出了一种考虑系统损耗的方法，以获得精确的计算结果。然后讨论了系统同步电容器的视在功率。并对轴带发电机系统的暂态性能进行了详细的分析。推导了系统的暂态方程，计算了系统在直流输入电压阶跃变化情况下的暂态响应，并与实验结果进行了比较。还研究了系统负载阶跃变化情况下的暂态响应。最后，以感应电机为负载，对轴带发电机系统的暂态性能进行了分析。首先介绍了一种简单的电机暂态模型。该电机模型与轴带发电机系统的暂态模型是统一的。利用该框图对感应电机与轴带发电机输出端连接时的暂态响应进行了仿真。将仿真结果与被测系统的实验结果进行了比较，验证了该理论的有效性。研究了轴流发电机系统中同步电容器和感应电机的转动惯量对系统暂态性能的影响。
