摘要

This paper presents the mitigation of current harmonics in the stator of a Wind Energy Conversion System based in a doubly fed induction generator and a back to back converter. This converter consists in a Rotor Side Converter and a Grid Side Converter, and the current harmonics mitigation occurs through the selection of the PI parameters in the Rotor Side Converter control. The case of study is a test rig based on a 372W doubly fed induction generator, and the considered grid voltage harmonics components are fifth and seventh. Simulations are implemented in PSIM in sub-synchronous speed, testing different frequencies designs in the Rotor Side Converter control in order to evaluate the current harmonics compensation.
