Wind Turbine Rotor Blades

Rotor blades are the core of wind turbines. They determine the maximum harvest of wind energy. Their full functionality and security against fatigue and degradation has to be designed and assured for a service life of at least twenty years. Meanwhile, keeping pace with the rapid development of the market, rotor blade size is steadily increasing particularly for off-shore operations. In order to meet the requirements within the framework of design, development and construction of rotor blades, a comprehensive knowledge of the specific essentials, e.g. of the outer and inner stresses and strains, computing and evaluation methods, and material capability and performance characteristics is necessary. Durable construction and optimised production technologies, therefore, are necessary prerequisites for long service intervals, just as new and yet to be developed structural health monitoring systems (SHM) are. Experience shows that quite a lot of damage can still occur to existing rotor blades and that a lot of problems in this area are not solved yet. Also, the solution to the problem of disposal is still in its infancy.

Wind farm development and technical due diligence

The fundamental framework of conditions for the total operational duration of generally 20 years are put in place during the development phase of a wind farm project. Even project risks, which might affect the project profitability only in the medium or long term often originate in the early project phases. To identify and minimize these project risks, as far as possible, should be the goals of a durable successful project development.

Drivelines in wind power installations

Requirements for Gears, Couplings and Bearings

The rapid developments in wind turbines should not mislead us to overlook the fact that often in turbines, particularly of high performance categories, technical faults and even damages occur in various elements of the drivelines (gears, couplings and bearings), which in drivelines of comparable size in other industries or branches of industry (e.g. heavy rolling mill drives) have so far been unknown. The main reason for this, on the one hand, lies in the fact that the basic support structure of a wind turbine consisting of tower and nacelle are very elastic and in combination with the rotor presents an extremely occilation-susceptible system.

Towers and Foundations for Wind Energy Converters

In the meantime, wind energy has advanced to one of Germany's largest renewable energy sources. 19,460 wind energy converters (WEC), with a total power rate of more than 22,247 MW, have been installed in 2007. These have helped reduce the annual CO2 emission by approx. 35 million tons. However, the structural engineers are faced with new challenges concerning the substructure designs of ever larger WECs.
