The modern large-scale wind generating set adopts a three-blade layout, the Cp-lamda curve is relatively gentle, the stress is relatively balanced, the aerodynamic performance of the two-blade wind wheel 1 is more advantageous for a small-scale distributed wind power system, and the installation is simpler and more convenient due to the fewer number of blades, and the cost is lower. Based on the two-blade three-blade and two-blade configuration scheme, the three-blade has the advantages of being high in bearing capacity of the three-blade structure and low in cost of the two blades, and the influence of the number of the blades on load fluctuation can be fully compensated.
