Ventus Engineering GmbH, supplier of the standard been certified from DNV according to envelope for excellence in wind turbine performance, has end to end optimization solutions within the type approval DNV-SE-0439-2021-10 Certification of Condition Monitoring for Wind Turbines, for its Dynamic Relative Blade Pitch angle Misalignment (DRBPM) inspection service.
This innovative technology, consisting of a high-speed camera coupled with onsite image processing software, which accurately and efficiently measures relative blade pitch angle misalignment while the turbine is still in operation.
Just 1° of relative blade pitch angle misalignment between two blades could result in 2% loss of power production and additional loads.
The cutting-edge Dynamic Blade Pitch Angle Measurement performed while the wind turbines are in operation enables Ventus to accurately see the relative blade pitch misalignment, and on the affected wind turbines then blade pitch angles can be adjusted to be within +/- 0,30 as required.
Ventus offers this service on wind turbines located both on- and offshore.
The DNV certification comes as Ventus Group experiences a period of fast expansion on a global scale. Headquartered in Austria, the company has a well-established presence in Europe and the UK, with 2021 also seeing it enter the Indian market for the first time.
The DNV evaluation assessed and finally certified the overall method and procedure performed by Ventus for the accurate calculation of relative blade pitch angle misalignment between the wind turbine blades, with a review of the respective documentation material and field demonstration.
Ventus Group CTO Poul-Anker Lübker, comments: “The certification from DNV is a unique technological benchmark for the industry. It means our customers can put their trust in our top- level analysis methods and documented results.”
