Surveying Synchronous Machine Sudden Short Circuiting Phenomenal by EMTP

Abstract

Applying ATP-EMTP for the purpose of thorough understanding of rotating machine transients, several kinds of model synchronous machines with typical features were analyzed in time domain as for sudden short circuiting, the calculated currents and flux linkages of which were plotted on the d-q domain planes. Many interesting current/flux vector traces, representing rotating machine transients during short circuiting, were obtained. These could, hopefully, be good help for understanding rotating machine transients.
