Abstract :
This paper presents harmonic analysis of a fixed-speed wind turbine in a utility distribution system. It shows a condition of how the wind turbine may be involved in harmonic resonance through its power factor correction capacitors. In addition the effect of wind speed on the resonant frequency is also considered. The test system used in this study is a distribution feeder with an equivalent nonlinear load and a wind turbine connected at the feeder end. The results show that severe harmonic distortion can occur due to the interaction of the power factor correction capacitors and the system impedances. Although, wind speed does not have a direct effect on the resonant frequency, the number of power factor correction capacitors affects the resonance condition. A single-tuned notch filter is shown to be efficient in reducing the harmonic distortion.
