The present invention relates to a blade for a wind generation system, and more specifically, to a blade for a wind generation system which divides a portion of a flat back type blade, and operates the divided blade to control a pitch angle. Provided is a blade for a wind generation system which includes a flow separation prevention wall blocking introduced current flowing in a gap at the divided blade to prevent flow separation at the divided portion. According to the present invention, the flow separation prevention wall preventing flow separation is disposed at a pitch operation portion of the flat back type blade, such that, when rotating the flat back type blade by wind power, flow separation is prevented at the blade to improve efficiency of the blade operation. |
