Video: Wind Turbines In Virtual Endurance Test
The wind energy industry is changing: On the one hand, experts see that the electricity generation of the future will be in wind energy. By 2025, around 10% of global energy consumption could be covered by wind energy. Offshore systems in particular play an important role, since the weather conditions at sea are significantly better than on land and the strong and steadily blowing winds at sea can generate almost twice as much electricity. As the Foundation Offshore Wind Energy announced in January of this year, electricity generation from offshore wind energy was about 13 terawatt hours last year. This corresponds to an increase of almost 57% compared to 2015.
The balancing act in wind energy
On the other hand, increasing competition, declining government subsidies and lower natural gas prices are putting wind turbine manufacturers under pressure. To be competitive, they need to reduce their development, production, and operating costs. And they have to drastically reduce the time between product development and product launch - while increasing the performance and reliability of their wind turbines - a balancing act. Specialized software solutions already support manufacturers in meeting these market challenges. For example, Dassault Systèmes offers with its industry solution "Sustainable Wind Turbines" based on the 3D experience platform a comprehensive solution for the construction, analysis and production planning of wind turbines.
From the preliminary design to the rotor blade
The construction of wind turbines is a complex process. This applies not least to the design of rotor blades, which are among the most expensive components with a share of 20 to 25% of the total costs of a wind turbine. They are exposed to a variety of stresses, from high wind speeds to icing. Nowadays they are mostly made of fiber composite materials. Because these have, among other things, high rigidity and wear resistance as well as a low weight. The design requires manufacturing process studies, aerodynamic calculations as well as load and life tests. That is why rotor blades can only be developed and developed in the course of close, cross-disciplinary cooperation.
Use optimization opportunities
Even though many manufacturers already master the design process very well, some still give away opportunities for optimization that they find expensive. For example, preliminary design, detailed construction, calculation methods and production are mostly isolated processes, supported by isolated software solutions. If the individual departments do not have a common information platform, the necessary data exchange between them takes a lot of time. Time that drives up costs and, above all, extends product launch time. In addition, manual data transfer between departments is an additional source of error.
