Simulation and analysis of switched reluctance generator for renewable energy applications

The purpose of the paper is to investigate the application of a Switched Reluctance Generator (SRG) for future wave energy converters. This machine presents some favourable features as compared to others. The machine optimal operation can be obtained after a detailed assessment of the control strategy. For this purpose, a SRG model is implemented in Matlab® Simulink® environment to find out the values of the switching angles which maximize the converted power and to set up an appropriate control of the power exchange with the grid to which the machine is connected. The simulation results provide evidence that a proper advancing of the turn on angle enables an optimized power extraction, fulfilling at the same time the control references on DC link voltage and grid reactive power.
