Abstract
This paper presents a complete analysis of a Static Synchronous Compensator (STATCOM), when it is intended to support a wind farm based on induction generators. Grid disturbances affect wind turbines with fixed speed generators directly connected to the grid, because they generate electromagnetic torque oscillations during and after faults. As a consequence, mechanical stress is presented in the gearbox and premature aging is prone to happen. In this work, an indirect control for STATCOM, for electromagnetic torque oscillation reduction purposes during and after the fault is proposed. In this abstract only an unbalanced fault at the point of common coupling (PCC) bus will be simulated and presented on a reduced model of a wind farm.
