The bond graph technique, which has been related almost entirely to the field of mechanics, is a modeling procedure where emphasis is placed on the flow of power and energy in a system. Through specific digital simulation programs such as ENPORT IV and V and THTSIM the state space representation, associated output equations and system dynamic response are directly obtainable from the bond graphs. This approach has a great advantage where a complex system is composed of electrical, mechanical, thermal, hydraulic or pneumatic subsystems, such as would exist, for example; in a boiler, turbine, generator exciter system together with its associated controls. The purpose of this paper is three-fold: (1) to develop interest in the bond graph modeling technique in power engineering (2) to develop bond graph models for typical synchronous and induction machines which are not as well developed in the literature as are the graphs of mechanical components and (3) to complete some of the missing links in the development of bond graphs for electromechanical machines. Standard well known orthogonal axis transformations are used in the model development. The bond graphs thus developed from accurate mathematical relations can be easily integrated into other electrical or non-electrical systems through the power bonds of the graphs.
