Modeling and Simulation of a PMSG-based Marine Current Turbine System with inter-turn faults

Abstract

This chapter deals with modeling and simulation of a permanent magnet synchronous generator (PMSG)-based marine current turbine (MCT) with inter-turn faults. The generator is modeled in healthy and faulty conditions by using the (abc) reference frame and the (dq) reference frame. Indeed, the PMSG, installed under the sea (existence of the swell and wave), can be exposed to higher voltages and/or currents transited, which leads to the appearance of various faults. In this chapter, the faulty mode deals with the study of the stator inter-turn short-circuit faults in the PMSG. In fact, this fault presents a big problem because it can lead to the total degradation of the machine. Simulation results are carried out by using Matlab/Simulink environment.
