Abstract
The present invention relates to a method and apparatus for judging an unnecessary windward condition and a method and system for tracking wind, wherein the method comprises: taking a first wind sample by using a wind sampling-detecting unit, detecting and obtaining a wind direction thereof; judging whether an intersection angle between the first wind direction and a current wind turbine orientation is smaller than a critical angle of rotation; if “yes”, determining the windward condition is unnecessary windward condition; if “no”, detecting a wind speed of the first wind sample, judging whether the detected wind speed is lower than a first critical wind speed; if “yes”, determining the windward condition is unnecessary windward condition; if “no”, determining the windward condition is not unnecessary windward condition, then rotating the cabin of the wind power generating set, thereby achieving accurate windward according to a wind condition, a cabin position, and so on.
