Abstract: Building mathematical and simulation models of the automatic control system of a salient pole synchronous motor with a damper winding is proposed in this article. It’s supposed that the models which have been obtained in the work and the approach to their construction will be useful further in designing real electric drives, regardless of their application.
The urgency of the discussed issue. A frequency controlled electric drive with a synchronous motor is becoming increasingly widespread as a drive for especially large aggregates and installations. A field excited synchronous machine is a complex multidimensional nonlinear control object that accordingly affects the complexity of automatic control system building. Complication of synchronous machine design due to use of damper winding often creates an additional difficulty in building the automatic control system. In this connection, the issue of developing a unified approach to building the automatic control system for the synchronous motor with the damper winding becomes quite relevant.
The main aim of the study: development of the universal mathematical apparatus for the successful synthesis of the automatic control system of the synchronous machine with damper winding and simulation of the above system for evaluation of its quality indicators.
The methods used in the study: mathematical modeling based on the operator method for calculating electromechanical systems; simulation modeling in the graphical programming environment MATLAB Simulink.
The results. Mathematical and simulation models of the automatic control system of the frequency controlled synchronous motor with damper winding, the dynamic characteristics of electric drive model and comparative analysis of its transient processes with those observed in the model without damper winding are presented in this article.
