DFIG Driven Wind Turbine Grid Fault-Tolerance Using High-Order Sliding Mode Control

Abstract

International audienceThis research note deals with grid fault-tolerance of a doubly-fed induction generator-based wind turbine using high-order sliding mode control. Indeed, it is proposed to assess the main and attractive features of high-order sliding modes which are robustness against external disturbances (e.g. grid) and chattering-free behavior (no extra mechanical stress on the drive train). Simulations using the NREL FAST code on a 1.5-MW wind turbine are carried-out to evaluate ride-through performances of high-order sliding mode control
