Wind energy yearbook

Half of it consists of data sheets for 92 wind turbines, large and small. This time, the nominal capacities range from 0.165 to 5,075 kW. Since the yearbook describes the European market, there is no information about the megawatt turbines from the Chinese manufacturers, from Suzlon (India) and from Clipper Windpower (USA).

Before the data sheets, there are several technical articles providing information about current developments, such as experiences in repowering and the benefit of the system service bonus (SDL bonus). A longer contribution deals with the issue of manufacturer service and the independent service providers, who want to gain market share.

On 52 pages, addresses of banks, manufacturers, component suppliers, consultants and other providers of goods and services are listed. A very informative part is the presentation of the turbine operating results for 2009. It allows about 1,500 wind turbines in Germany, the data for which is reported monthly, to be compared on the basis of the listed details.

It is particularly easy to compare different turbine types at the same locations, since the operating results are sorted by postcode. Although last year was relatively poor in terms of wind energy yield, even several inland wind turbines achieved over 1,000 kWh per square metre of swept rotor area.

Sometimes one and one add up to more than the mere addition of numbers. Structural Health Monitoring (SHM) of rotor blades is a complex and demanding task that requires very good hardware as well as professional data analysis in order to be able to make really precise and early statements about structural damage to the rotor blade. For this reason, two specialists have now joined forces to offer wind farm operators the best possible combination of forces on the market.

More efficient: Pulcap pultruded profiles reinforce the blades of today’s wind turbines (pict. Röchling)

As part of the planned energy transition, increasingly wind power plants are being used to generate electricity. The international plastics processor Röchling Industrial launches a product made of composites, Pulcap, that enhances the stability of the rotor blades of wind turbines. Owing to their extremely high mechanical strength and low weight, the pultruded profiles enable an efficient and safe operation of wind turbines.
