- Abstract
An overall revision of the conventional approach to power in electrical engineering courses at Universities is taking place in order to enable the power engineer to cope with new developments in the field of electrical engineering. In the past, courses in power were primarily concerned with rotating machines, their steady state performance and design. The theories involved had been developed by early machine designers and stood out for diversity in the treatment of different classes of machines.
Basically there are two ways to analyse electrical devices, the first involving the use of field theory and the second using a lumped parameter approach. As far as electromechanical transducers and rotating machines are concerned the latter is being found more suitable, although an understanding of electrical fields and their interaction is still required when deducing lumped parameter characteristics in the first place.
Dynamic circuit theory deals with lumped parameter representation of electrical devices allowing for moving fields and associated electromechanical energy conversion. It so forms the basis for the study of electromechanical transducers covering, alongside conventional machinery, also the complete field of devices which are receiving more and more attention as part of the evolution of control and power system engineering.
The aim of the paper is then to introduce the basic concepts involved in developing a dynamic circuit theory and to demonstrate with examples the fact that the theory allows us to go beyond conventional approaches in the treatment of transient phenomena and systems of interconnected transducers.
