Electrical Power from the Wind - The First Attempts,with a power output of about 500 kW (in 1882) and in Berlin (1884) . Three-phase current was introduced as early as 1891. Power plant technology evolved rapidly and produced ever-increasing power outputs. By the beginning of the twentieth century, almost all large cities in the industrialised cou

Basic Concepts of Wind Energy Converters,ost bizarre concepts have been proposed . Museums and patent offices are filled to the rafters with more or less promising inventions of this type. In most cases, however, the practical applicability of these “wind power plants” falls far behind the inventors’ expectations.

Physical Principles of Wind Energy Conversion,y. For the initial discussions of principles, the exact nature of the energy converter is irrelevant. The extraction of mechanical energy from a stream of moving air with the help of a diskshaped, rotating wind energy converter follows its own basic rules.

Loads and Structural Stresses,urricanes. However, the continuous alternating loads - even under normal wind conditions - are just as problematic. Alternating loads are more difficult to cope with than static loads because the material becomes ”fatigued”.

Mechanical Drive Train and Nacelle,mployed. Thus there are associations with aircraft engineering. A look into the nacelle provides a completely different picture. The components for converting mechanical energy into electrical energy represent ”conventional” power plant technology, as it were. But a conclusion that this area would b

The Tower,n amount to up to 30 % of the overall turbine costs, are, of course, disadvantageous. As the height of the tower increases, transportation, assembly and erection of the tower and servicing of the components also become increasingly more difficult and costly. On the other hand, the specific energy yi
