The total capacity of wind turbine generator systems (WTGSs) operating in the world reached 27 600 MW in Autumn 2002. In the European Union (EU) coun- tries, wind generators capacity of 20 500 MW were operational. Most of them were located in Germany (10 650 MW), Spain (4100 MW) and Denmark (2500 MW). The Danish electric power system has the largest ratio of the capacity of WTGSs to the capacity of all sources of energy and it reaches about 30%. The mean value of the rated power ofWTGSs sold in 2000 was 930 kW. Today, wind generators with a rated power equal to 2 MW have become standard. The...
