   Sammanfattning : The thesis focuses on a forced-commutated voltage source converter (VSC) connected to a grid in a wind energy application. The work consists of four parts. The first part addresses the type of electrical system which should be used in a wind turbine. LÄS MER

4. 3. Design of Direct-driven Permanent-magnet Generators for Wind Turbines

   Författare :Anders Grauers; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; direct drive; synchronous generator; wind turbine; design; low speed; permanent magnet; frequency converter;

   Sammanfattning : This thesis presents an investigation of how a direct-driven wind turbine generator should be designed and how small and efficient such a generator will be. Advantages and disadvantages of various types of direct-driven wind turbine generators are discussed, and a radial-flux permanent-magnet generator connected to a forced-commutated rectifier is chosen for a detailed theoretical investigation.
