Abstract:
A blade icing state identification method and apparatus for a wind generator set are disclosed. The method includes setting a preset wind speed threshold and a preset rotating speed threshold, and setting the preset rotating speed threshold as a lower limit value of a maximum limited rotating speed of the wind generator set operating under a limited power condition; comparing a current wind speed and a current rotating speed of the wind generator set with the preset thresholds respectively; progressively increasing a blade icing possibility index when the current wind speed is greater than the preset wind speed threshold and the current rotating speed of the wind generator set is smaller than the preset rotating speed threshold, and otherwise, progressively decreasing the blade icing possibility index; and determining that blades are in an icing state when the blade icing possibility index is greater than a preset index.

Claim (Index 9):
The apparatus of  claim 6 , wherein the preset wind speed threshold is smaller than a wind speed value corresponding to a minimum torque of a constant rotating speed section in which the rotating speed is a preset maximum rotating speed in a torque-rotating speed characteristic curve of the wind generator set under the limited power condition.
