- Abstract
- We have extended the study of the functioning of the self-controlled synchronous machine from Chapter 1 to take into account the influence of the overlap angle. For this purpose we have applied a general method of definition of circuits to the definition of the armature circuit. This method has led to a dynamic model that takes into account the behavior of the damper windings. The model obtained has three electromechanical variables. The first, ρ, is a sliding variable defining the position of the armature circuit (which can be represented by the position of the fictitious brushes). The following two, μ and ν, are non-lineic variables according to the meaning of the sliding circuit theory developed by Garrido. Variable μ can be represented as the width of the fictitious brushes, whereas variable ν describes the current form during overlap intervals. We have presented the theory in the form where the flux of the armature circuit and the fluxes of the damper windings are electrical state variables. This model is sufficiently simple to be used within the framework of control and regulation systems. Finally, we have shown that this model can be put in a Lagrangian form, which opens the way to taking account of magnetic saturation.
