Horizontal Axis Wind Turbines

This paper presents a dynamic response analysis of the blade of horizontal axis wind turbines using finite element method. The blade is treated as a thin-walled beam based on the classical lamination theory, and accounts for arbitrary material layup and non-linear anisotropic fibre-reinforced composites. Applying the proposed method,A 29 m rotor blade, previously reported in specialized literature, was chosen as a case study the dynamic behaviour built in a FEM software tool. It is developed to predict natural frequencies and corresponding vibration modes in rotating blade in-plane and out-of-plane. Numerical results are serve as a design tool for the large composite wind turbine blade structure required during design and optimization.

Turbine Blade Design

Today a large-scale wind turbine blade can be 70 m long and 5 m in root chord length, and it is fabricated in a single piece. This feature leads to high initial costs, as transportation of a large blade requires special trucks, escorts, and road adaptations. These constraints can account for approximately 6–7% of the total investment for the blade. In addition, the manufacturing process commonly used is a hand lay-up configuration of thermoset composite sheets. These materials are not reusable after fabrication, which is a non-renewable feature of existing systems. The project consists of manufacturing thermoplastic composite blades in segments, which are joined before installation at the turbine site. This paper addresses the preliminary research results when conducting design and fabrication of a small blade with this innovative approach. Three segmented blades are manufactured for a horizontal-axis wind turbine, with each blade having a 50 cm span and a 4 cm tip chord length. The blade size and profile are designed based on the idealized Betz limit condition. The material used for manufacturing is a glass fiber reinforced thermoplastic composite system with a polypropylene matrix that melts at 200 °C. Each blade is fabricated in 4 independently manufactured pieces, consisting of top/bottom, and tip/root segments, via a vacuum assisted thermoforming technique. The parts will be assembled afterwards by a joining process, forming the final part for site testing.

Design And Optimization

Wind turbine blade is an important component to capture wind energy and converse energy. Basing on Wilson optimization method and engineering pratice, 2MW wind turbine blade’s aerodynamic profile is designed. Meanwhile, in order to avoid the resonance damage, top 10 rank modal frequencies and displacement gradient distribution contours are obtained through modal analysis. The results show that blade’s natural frequency does not coincide with the external excitation frequency, which avoids the resonance damage. Blade’s major vibration forms are waving and shimmy, requiring the ability of excellent resisting torsion. Therefore, the design should enhance bending stiffness of the blade. This paper provides an effective method for large wind turbine blades’ design and optimization.
