Abstract

The article presents differential equations of a synchronous generator transformed according to the theory of two reactions, that is, in the axes d-q. We consider the influence of transformer EMF on transients. We prove that for the accurate calculation of transients in an electric power system it is necessary to use differential equations of the synchronous generator taking into account the transformer EMF in its stator.
