Block Diagrams and Transfer Functions of the Synchronous Machine

The synchronous machine can be represented by a simple and easily surveyed block diagram from which can be derived all possible transfer functions. Because of the introduction of complex representation of input and output quantities, this block diagram is valid for the positive as well as for the negative-sequence system of the stator. These transfer functions for the positive and negative sequence in the p-domain, and for positive sequence only in the t-domain, are shown in tables.
