Simulation of an asynchronized synchronous machine

This paper describes a detailed analogue computer simulation of an asynchronized synchronous machine, which is suitable for investigating both steady-state and transient performance. A simple method is presented for simulating asynchronous operating conditions, and developed to provide the required excitation control. This demands continuous sine and cosine functions which are variable in both magnitude and phase. Sample results are given which illustrate the effects of derivative signals in the excitation control loops.
