Validation of a Wind Turbine Harmonic Model based on the Generic Type 4 Wind Turbine Standard

This paper presents the development and validation of a Wind Turbine (WT) harmonic model for harmonic analysis in power systems. For that purpose and based on standard WT generic models, some changes and the implementation of additional structures are proposed to represent the influence of the wind turbine in the frequency domain. The validation of the model is done with a comparison between the results obtained from the WT harmonic model implemented in Matlab/Simulink and an experimental platform. The experimental results are performed on a test bench with a downscale version of the INGECON WIND MV100 commercial converter of Ingeteam manufacturer. The harmonic emission is tested for two modulation strategies, the typical CB-PWM and a new synchronous SHE-PWM based modulation. The results show good agreement between the model and the real converter.
