This paper discusses the synchronization phenomena of wind turbines in a wind farm. The phenomena denote the situation that a blade revolution of a wind turbine is pulled into phase with that of the other turbines in a wind farm. If blades of many turbines simultaneously pass in front of their towers, output power fluctuations of the turbines due to tower shadow effects also become synchronized. This causes voltage fluctuation to increase and may give rise to voltage flicker problems. The purpose of this paper is to examine the phenomena theoretically. Obtaining a differential equation that describes the phenomena with output power, voltage and slip fluctuations of a wind turbine, we examine dependence of the phenomena on the related parameters. We also prove the validity of the equation through simulation analyses.
