This article presents the design, simulation and fatigue analysis of various aerodynamic profiles used in low power wind turbines. For this purpose, the model of a blade of a horizontal axis wind turbine with a nominal power of 5 kW is developed. The analysis of the lift, drag and power coefficients of the aerodynamic profiles was carried out with the XFLR5 software. The methodology used for the blade design is based on the interactions and convergence method called BEM. Also, to simulate the structural and aerodynamic part of the element, the QBlade program was used. With the main objective of ensuring that the fatigue safety factors mentioned in the IEC 61400 standard are achieved, the Simplified Load Model was applied. The maximum fatigue value of 21,421.66 N and the maximum flapwise moment value of 698.41 Nm were obtained.

ABSTRACT Generally, the environmental wind speeds in urban areas are relatively low due to clustered buildings. At low wind speeds, an aerodynamic stall occurs near the blade roots of a horizontal axis wind turbine (HAWT), leading to decay of the power coefficient. The research targets to design canards with optimal parameters for a small-scale HAWT system operated at variable rotational speeds. The design was to enhance the performance by delaying the aerodynamic stall near blade roots of the HAWT to be operated at low wind speeds. For the optimal design of canards, flow fields of the sample blades with and without canards were both simulated and compared with the experimental data. With the verification of our simulations, Taguchi analyses were performed to seek the optimum parameters of canards. This study revealed that the peak performance of the optimized canard system operated at 540 rpm might be improved by ∼35%.
