The Nonlinear-buckling Analysis of the Wind Turbine Blade Subcomponent

The national-level orientation is to cut diverse costs through the development of high-power wind turbines, which has promoted the growth of higher-power wind turbines and larger-size blades to some degree. However, the excessively rapid development has led to the immaturity of technology for the whole industry chain and technology for part design and manufacturing, bringing more technical risks and costs. Blade is the source of all designs, and its length determines load costs, the level of power generation and complete machine costs to some degree. How to cut costs and pursue high power generation benefit through high power while properly considering the technology maturity of the supply chain will be a key technology.

Large Rotor Blade Design Optimization for Lower LCOE


Ding Suo
Certification Engineer, Sinoma Wind Power Blade Co., Ltd

When everybody calls for parity, under what principles can we achieve our goal through the matching between parts and complete machines. Therefore, static empty load will be viewed as the primary requirement in the process. To achieve parity design of parts, design specifications, design & demand, and design & input will matter most. How to put forward the goal of blade design from the perspective? Firstly, as a multidimensional, multidisciplinary and multi-principled design process, the proportion of load is still important, and the weight determines the cost of blades, which are of equal importance. Another question is how to put the levelized cost of energy (LCOE) indicator in blade design. At present, we are facing the problem of parity. For blade design, we can find some thoughts and answers through the boundary design optimization of large models, but have also discovered more problems.

Next Generation Wind Turbine Blades


Xu Lan
Director of Development, Front End Engineering, LM Wind Power

LM Wind Power became the world's first wind power enterprise achieving carbon neutrality in 2018. When blades become larger and larger, what will be the limiting condition? I think it depends on costs eventually. If blades are very big while the cost per kilowatt hour of electricity can be reduced, I believe blades will be manufactured as large as possible. When wind turbines can achieve the power of over 20MW, what will they look like? Wind turbines may not have the horizontal axis, and blades may be different from what they look like now. This is worth considering.
