本文对电力系统中利用电模拟物模拟猎动现象的理论考虑作了初步探讨。主要的假设是，在机器转子的极轴偏离其正常稳态状态的情况下，这种角位移的振幅必须很小。作为一个例子，建立了一个简单的电气模拟来模拟给定的机电系统。在模拟实验上测定的自然振荡的频率和幅度与数学分析的结果吻合得很好。为了将范围扩展到系统稳定性问题，介绍了一种利用模拟计算机技术的10kc /s网络分析仪。主要目标是制造一种装置，不仅能够解决稳态稳定性问题，而且能够直接产生暂态问题的系统摆动曲线，而不需要像通常的交流网络分析仪那样进行一步一步的计算。该分析仪的进一步工作正在进行中，并将在未来的论文中报告。
The paper presents an elementary approach to the theoretical considerations upon which electrical analogues can be used to simulate hunting phenomena in power systems. The major assumption is that in the case of a deviation of the pole axis of the rotor of a machine from its normal steady-state condition, the amplitude of such angular displacement must be small. As an example, a simple electrical analogue is set up to simulate a given electro-mechanical system. The frequency and amplitude of natural oscillations determined experimentally on the analogue agree very well with the results of a mathematical analysis.In order to extend the scope to system stability problems, a 10-kc/s network analyser utilizing analogue-computer technique is described. The main object is to produce a unit capable not only of solving steady-state stability problems, but also of producing directly the system swing curves for transient problems, without the necessity for step-by-step computations, as are required with the usual a.c. network analyser. Further work on this analyser is being carried out and will be reported in a future paper.
