本文描述了一个数学模型的发展，其中包括一些通常被忽视的现象，在数字计算机的研究。该模型提供了更准确的阻尼比简单的方法，使用一个扭矩成比例的滑移表示。为了更精确的解，它包括描述磁链变化的微分方程。计算结果进行了比较，一个大型的涡轮交流发电机，包括电压调节器和总督的测试结果，以及从微机械实验在帝国理工学院，英国伦敦大学的测试结果。包括计算曲线，以显示更精确的方程所带来的详细变化。本文对适用于数字计算机的各种数值积分技术的方法和布局进行了比较研究。比较解决方案的时间表，并讨论了集成技术的优点。
The paper describes the development of a mathematical model which includes some of the phenomena commonly neglected in digital-computer studies. The model provides for the representation of damping more accurately than the simple method using a torque proportional to slip. For an even more accurate solution, it includes differential equations describing the variation of the flux linkages. Calculations are compared with test results of a large turboalternator incorporating a voltage regulator and governor, as well as with test results obtained from micromachine experiments at Imperial College, University of London, England. Calculated curves are included to show the detailed changes brought about by the more accurate equations. A comparative study is made of various methods and arrangements of numerical-integration techniques suitable for a digital computer. A table of comparative solution times is presented and the merits of the integration techniques are discussed.
