Modeling, Simulation, and Experiment of Switched Reluctance Ocean Current Generator System

الملخص EN

This paper presents nonlinear simulation model of switched reluctance (SR) ocean current generator system on MATLAB/SIMULINK with describing the structure of generator system.

The developed model is made up of main model, rotor position calculation module, controller module, gate module, power converter module, phase windings module, flux-linkage module, torque module, and power calculation module.

The magnetization curves obtained by two-dimensional finite-element electromagnetic field calculation and the conjugated magnetic energy graphics obtained from the three-dimensional graphics of flux linkage are stored in the “Lookup Table” modules on MATLAB/SIMULINK.

The hardware of the developed three-phase 12/8 structure SR ocean current generator system prototype with the experimental platform is presented.

The simulation of the prototype is performed by the developed models, and the experiments have been carried out under the same condition with different output power, turn-off angle, and rotor speed.

The simulated phase current waveforms agree well with the tested phase current waveforms experimentally.

The simulated output voltage curves agree well with the tested output voltage curves experimentally.

It is shown that the developed nonlinear simulation model of the three-phase 12/8 structure SR ocean current generator system is valid.
