Abstract

This paper assesses the effect of an inter-turn short circuit fault in stator windings of a Permanent Magnet Synchronous generator (PMSG)-based variable speed wind energy conversion system (WECS) connected to the grid by a power converters interface. The objective is to assess the impact of the fault on the WECS performances. This study has two tasks. The first one details a dynamic modeling of different subsystems of the WECS. The mathematical model of the defective PMSG is also set up. The second one presents an appropriate control strategy for the power converters interface. The control of the PMSG-side converter aims to ensure the operation in maximum power point tracking. The grid-side control was also established by controlling the active and reactive powers to ensure the operation in unity power factor and keeping the DC bus voltage stable. The performance of the control design was tested under healthy and faulty conditions.
