“Electrical systems of wind turbines” at the Haus der Technik Germany stand nearly 20,000 wind turbines (WTS) with a potential of approximately 400 billion kWh and the growth trend continue 1. But how does the use of wind energy in individual wind Turbines and wind farms? What challenges are to solve for the power supply? How interlocks the complex interplay of generator, power electronics and control? The Symposium “Electrical systems of wind turbines” in Essen Haus der Technik treated these and many more questions. Under the direction of Prof. Dr.-ing. Detlef Schulz of the Helmut Schmidt University in Hamburg is illuminated the overall understanding of the electrical system in many facets: different generator types and modes of operation, function and effects of frequency converters, power control, typical damage during the operation of wind Turbines as well as the legal framework of the network connection policy and network integration. Provides a basic overview of the Symposium on 26 and 27 January 2008 in Essen the wind energy technology in theory and practice and is recommended for Brancheneinsteiger, as well as employees with appropriate electrical qualifications of suppliers, insurance companies, banks and investors.
