Harmonic analyzing of wind farm based on harmonic modeling of power system components

The aim of this paper is to present a harmonic model of wind farms using DFIG whereas all power system components are modeled in harmonic domain. After analyzing the effects of harmonics in power system, it is tried to model all the power system components such as transmission line, transformer, shunt reactor, load and back to back converter in harmonic domain. When the inverter DC voltage is converted into an AC output, during this transformation from DC to AC, harmonics affect the power quality of the network a lot. The simulation results show that the presented model has enough accuracy to extract the futures of power system harmonics.
