Simulation Model of an AC Autonomous Switched Reluctance Generator

Switched Reluctance Machine (SRM) has a nonlinear behavior which difficults its understanding. The electric model shows this nonlinear behavior and it is difficult to derive conclusions but for the linear case. Simulators appear as the ideal tools for studying the machine. Although some papers report simulation models for this machine working in motoring and generating modes, the generating mode is only used for braking but not for generating electricity. In this paper the machine is used for generation purpose and the generated voltage and current are alternative instead of DC as usual. This difference enforces relevant changes demanding a new simulation model. The model has been implemented in Matlab/Simulink and allows analysis of linear and nonlinear cases. It has been used to study the working zones and its steady and transitory state behavior.
