Not a few types of d-and q-axis equivalent circuits for analysis of electrical transients of synchronous machines have been proposed. However these circuits, in general, have the same structure fundamentally except the rotor circuit composed of field and damper circuits. Therefore these several types of d-and q-axis circuits may be considered to have some properties in common. This paper investigates the fundamental properties of d-and q-axis equivalent circuits and basic equations by using the generalized d-and q-axis circuits whose rotor circuits are expressed by two-port networks.At first, the generalized d-and q-axis equivalent circuits are shown and the basic equations for analysis of electrical transients are derived from them. And the basic properties of the four transfer functions (d-and q-axis operational inductances, and two armature-to-field transfer functions) appearing in the basic equations are analyzed. Next, some problems encountered on constructing d-and q-axis circuits by using these transfer functions are noted. Finally, the fundamental theory of three test methods which are based on the determination of the transfer functions (frequency response method, three-phase short circuit test and stator decrement test) are developed by using the basic equations derived here, and their fundamental meanings are clarified.
