Presentation: development of ressource-saving wind turbine towers

On August 28th, 2020, our CEO Prof. Dr. Holger Lange gave a talk about the development of ressource-saving wind turbine towers on the 12th “Branchentag Windenergie NRW”. The motivation is based on the climate change, with temperature anomalies that keep increasing over the last years. It is also known that the production of concrete, steel, … Read more

Cooperation between Invers Industrievermessung & Systeme and P. E. Concepts

Cooperation between Invers Industrievermessung & Systeme and P. E. Concepts 1

On December 11th, 2020 P.E. Concepts GmbH and Invers- Industrievermessung & Systeme actively started their joint project. The two companies worked on a fun ride measuring project together and so far the progress looks successful. The project deals with the technical documentation as well as a partial verification of an existing fun ride (“Wilde Maus”) which is subject to certification.

As an established measuring company, Invers’ contribution included providing the necessary instruments and comprehensive know-how in the field of measurement technology. Particularly Invers provided a 3D laser scan which makes it possible to measure objects up to a range of 350 meters with an accuracy of ± 1 mm on 25 meters.  Furthermore, the environment to be measured is realistically displayed with high-resolution photos. Thus even a digital tour is made possible with this instrument.

As an established company in the fun rides industry, P. E. Concepts subsequently took over the evaluation of the measurement data, as well as the technical documentation of the ride . “The 3D scan offers the possibility of capturing these complex structures accurately and easily, which will make it no longer a problem to modify rides and to create construction books. Digitization offers many new possibilities here, and in the future we may even think about a ‘digital twin’.” – Prof. Dr. H. Lange, CEO of P. E. Concepts GmbH

Based on the successful cooperation, Invers and P. E. Concepts hope for further collaborations. “The cooperation of P.E. Concepts and Invers is a successful symbiosis, in which the expert knowledge of geometry acquisition and the analysis of data intertwine in an optimal way.” – D. Woytowicz, Managing Director Invers – Industrial Surveying & Systems

The prospect of wooden towers for wind turbine

In the past years there have been several developments of wind turbine tower made of wood, which may be lower in price, more climate friendly, and more flexible in the construction and transport. Though none of them ever made it to the market after the prototype stage. Our CEO Holger Lange says that most companies … Read more

Approach for peel stress prediction in adhesive joint of blades

It is important to estimate the peel stress in the adhesive joint in the trailing edge of wind turbine blades as it is subject to a fatigue loading. In finite-element-analysis, this joint is often modeled with solid elements connected with the shell elements of the blade. However, the stiffness discontinuity in this edge leads to … Read more

Vertical-axis wind turbine as an alternative

Compared to the common horizontal-axis wind turbine, for some people a vertical-axis wind turbine (VAWT) is an alternative that is more environmentally friendly. It causes less noise and it is also less dangerous to birds. Due to some disadvantadges, such as the problem of fatigue in the blades, VAWTs are usually only applied in smaller … Read more

Impact of blade shape distortion during manufacturing process

During the manufacturing process of blades for wind turbines, the shape may distort and thus there is a deviation from the designed target shape. What is the impact of this distortion on the turbine loads and the energy yield? Malo Rosemeier (IWES) and Matthias Saathoff (PEC) simulated two different models to analyze this issue. The … Read more

Stress-based method for lifetime extension of wind turbines

The calculation of the remaining lifetime of wind turbines is today often based on a comparison of loads. Here, we have to make many assumptions. How can the state-of-the-art methods be improved in such a way that the results are more reliable and not excessively conservative? We teamed up again with Fraunhofer Institute for Wind … Read more

Journal for small wind turbine enthusiasts

We work mainly with bigger wind turbines, but micro wind is also an exciting topic to us. They are small and the market development slow, but their potential is big and the opportunities remain promising. Check out the new journal on small wind released by E&M (Energie und Management) to be updated on this topic, … Read more
