Big data for wind energy – optimising costs and yield
At Husum Wind 2017 TÜV SÜD will present two new products for wind-energy turbines – an innovative digital inspection solution and a new site-specific certificate. At the trade fair the international service provider will also showcase their complete service portfolio offered to the planners, manufacturers, installers, investors and operators of onshore and offshore wind-energy turbines (Hall 4, Stand B407).
TÜV SÜD's new database-supported IT solution advances the development of wind-turbine inspection and the evaluation of inspection results. The fully digitised inspection combines highly-efficient processes and structured data recording according to the RDS-PP® reference designation system. The system is based on a language-independent code, which enables precise description and allocation of turbine components by location of installation and function.
During their inspections the TÜV SÜD experts enter the data on site with the help of mobile devices, such as smartphones or tablets and a special app. The app structures and classifies the findings and automatically sends them to an archive system. “Saving data systematically has many advantages”, says Dr Martin Webhofer, Head of Wind Energy at TÜV SÜD Industrie Service GmbH. These range from automated and prompt delivery of inspection reports to easier overall data management and preparation of informative statistics, on the most common defects, for example. “We make our WindApp available to our customers free-of-charge. The app works on the following operating systems: Android, iOS and Windows”, explains Dr Webhofer. Wind-farm operators and operation managers can thus benefit immediately from the advantages of digitised inspection.
New certificates consider site-specific requirements Adjustment of the design of wind turbines to a specific site can significantly increase the overall attractiveness of a wind farm. “Compliance of wind turbines with site-specific demands, such as wind conditions and licensing requirements, is mandatory”, says Dr Alexander Kupzok, Senior Expert Certification of Wind Energy Turbines at TÜV SÜD Industrie Service. “Nevertheless, there is still room for improvement in the turbine design for a specific location in the form of a cost-efficient tower and foundation design, adjustment of control functions, or even adjustments of the rotor and nacelle.” However, the integration of these variants for a great number of site-related conditions into one type approval certificate is complex and time consuming. “Our site-specific design certificate for wind turbines now offers manufacturers and project developers an efficient way of proving that their optimised turbines are suited for a specific site”, explains Dr Kupzok. The new certification is based on design examination within the scope of type certification and can include additional site-specific factors. The objective of the TÜV SÜD experts is to be able to prepare site-specific design certificates that can already be part of the wind-farm tendering process.
Wind energy services from TÜV SÜD TÜV SÜD looks back on a long and successful track record in the certification of both onshore and offshore wind farms, wind turbines and their components. The international testing and certification organisation also supports planners, manufacturers, installers, investors and operators in risk analyses, occupational health and safety concepts and quality assurance during construction. Other core fields of activity include quality assurance in component manufacturing, and periodic testing and inspection of wind turbines throughout their service lives. www.tuev-sued.de/windenergie.
