摘要： 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: Step 1: taking a first wind sample by using a wind sampling-detecting unit, detecting a wind direction of the first wind sample, and obtaining a first wind direction; Step 2: judging whether an intersection angle between the first wind direction and a current wind turbine orientation obtained by a wind turbine orientation device is smaller than a critical angle of rotation by using a control unit; Step 3: if the judging result of Step 2 is "yes", carrying out Step 3-1; if the judging result of Step 2 is "no", carrying out Step 3-2; Step 3-1: determining the windward condition is unnecessary windward condition; Step 3-2: detecting a wind speed of the first wind sample, judging whether the wind speed of the first wind sample is lower than a first critical wind speed; if the answer is "yes", determining the windward condition is unnecessary windward condition; if the answer is "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. With the technical solutions of the present invention, whether the change of the wind direction is an unnecessary windward condition can be judged and under the wind direction is an unnecessary windward condition, the system can enable the cabin to be windward under an optimum wind condition and capture maximum wind energy.
