METHOD AND CONTROL UNIT FOR CONTROLLING ONE OR SEVERAL WARNING LIGHTS IN A WIND TURBINE SITE TO MINIMIZE LIGHT POLLUTION

摘要

The present invention generally relates to the field of wind power. In particular, the invention relates to a method and a control unit for controlling one or several of warning lights in a wind turbine site in order to minimize light pollution from the warning lights. More in particular, the invention provides a control unit and a method for controlling one or several of warning lights in a wind turbine site. The one or several of warning lights illuminate up an air territory of the wind turbine site. The control unit comprising: receiving means configured to receive RADAR, Radio Detection and Ranging, information from one or several RADAR units observing said air territory;processing means configured to determine on and/or off decisions for one or several of the warning lights based on objects positions and movements in the air territory from the RADAR information. Wherein the on and/or off decisions are determined such as to minimize the number of on decision and maximize the number of off decision in order to minimize light pollution from the warning lights. The control unit further comprises control means configured to turn on and/or off the warning lights according to the on and/or off decisions.
