Abstract

This paper describes the effect of grid-connected wind turbines on the power quality in a distribution network. Special attention is given to stationary voltage conditions, flicker and harmonics. A probabilistic method has been developed for the analysis of stationary voltage conditions with the grid-connection of wind turbines. A method of calculating the flicker contribution of a given wind turbine to a given network is also described. The flicker contribution has been measured and analysed. Harmonics from pulse width modulation (PMW) frequency converter-connected wind turbines with variable rotational speed are evaluated.
