Presented at: European Wind Energy Conference 2004, London, UK, 22-25 november 2004.


An advanced generator control algorithm has been developed and implemented in ECN?s control design tool for wind turbines. For wind speeds above nominal the algorithm limits power and rotor speed to the common bounds of constant power control in variable speed turbines, while the electromagnetic torque varies half as much as found in literature. Simultaneously production dips at above nominal wind speeds are avoided. The algorithm has been examined by the aero-elastic wind turbine code Phatas. Application on a commercial wind turbine is in preparation.
