本文提出了计算固定电源电压下同步电机转矩和负载角变化的理论方法。为了补充和解释最近的全尺寸试验的结果，考虑了以下条件：（a）突然短路后的条件。(b)发电机和电源之间的电抗切换后的状态。(c)异步操作。(d)异步操作后的恢复。本文介绍了一种测量小型同步电机转矩和负载角变化的实验装置。该设备已被用于验证上述每个条件的理论结果。测试的机器是一个模型交流发电机或“微型交流发电机”，它模拟了一个典型的大型机器。这种专用的实验设备对于详细研究大型交流发电机性能的影响因素具有重要价值。
The paper develops theoretical methods of calculating the variation of torque and load angle of a synchronous machine connected to a fixed supply voltage. In order to supplement and explain the results of recent full-scale tests the following conditions are considered: (a) Condition after a sudden short-circuit. (b) Condition after switching in a reactance between the generator and the supply. (c) Asynchronous operation. (d) Resynchronization after asynchronous operation. In a companion paper experimental equipment for measuring the variations of torque and load angle of a small synchronous machine is described. The equipment has been used to verify the theoretical results for each of the above conditions. The machine tested was a model alternator or `micro-alternator' which simulates a typical large machine. The special laboratory equipment is of great value for studying in detail the factors governing the performance of large alternators.
