Abstract :
This paper deals with a Permanent Magnet Synchronous Generator (PMSG) driven by a Marine Current Turbine (MCT) through a PWM power rectifier and used for isolated sites. The generator model is established in the synchronous rotating dq reference frame. The control of the speed, the d-axis current, and the q-axis current is achieved using PI correctors. Robustness and performance of the considered system are evaluated in healthy and faulty conditions. The faulty mode deals with the study of single and multiple open-switch damages appearing in the PWM power rectifier. Simulations are carried-out to highlight the proposed PMSG-based MCT performance in both cases.
