Control of an Active Filter Based Three-Level Grid Connected Converter for Wind Turbine Applications

Abstract

Abstract.This paper presents a control design and implementation analysis of a three level grid connected converter to be deployed in large scale wind turbine applications, which main purpose is to obtain enhanced grid interaction by limiting its harmonic injection capability. The implementation of advanced power converter control in high power converters allows the proposed wind turbine system to provide active and reactive power supply while performing active filter functionalities for the 5th and 7th harmonic current components. Finally, the performance of the system is verified under several practical study cases by performing a laboratory analysis of the obtained results.
