HARMONIC AGGREGATION AND AMPLIFICATION IN A WIND-PARK

This paper studies the harmonic emission in a wind park, using a current transfer function. The emission of an individual wind turbine has been measured during a period of a few weeks covering all output productions. The wind park harmonic emission is analyzed by the average spectrum at the collection point. The amount of emission of the wind park as a whole is modeled by a stochastic method, based on the Monte-Carlo Simulation. The measured harmonics at wind turbines have been analyzed and compared with the simulated overall emission at the collection point of the wind park. The results will be showed by graphs and some discussions will be made.
