Sudden short circuiting of synchronous machines by EMTP

Applying ATP‐EMTP for the purpose of better understanding of rotating machine transients, several kinds of model synchronous machines with typical features were analyzed in the time domain with respect to sudden short circuiting, and the calculated currents and flux linkages during transient time interval were plotted on the d–q domain planes. Many interesting current/flux vector traces, representing rotating machine transients during short circuiting, were obtained. These may be helpful for understanding transients in rotating machines. © 2003 Wiley Periodicals, Inc.
