Series and Parallel Compensation for the Permanent Magnet Synchronous Generator at Chalmers Test Wind Turbine

Other conference contribution, 2006

The objective of the work at Chalmers test station is to carry out research, maintain and run the wind turbine at the plant. The station is used for research projects and as a demonstration and lab facility. The turbine is equipped with a permanent magnet direct-driven generator and an electrical system with a DC link suited for variable speed operation. Research focuses mainly on the generator and its electrical system. Series compensation of the PM generator is investigated. Theoretical studies show that the use of capacitors in series with generator windings in comparison to the present parallel capacitors can increase power output from the generator at a certain design speed interval. Both theoretical calculations and practical tests show that an increase in power by 60 % is possible.
