An analysis of the impact of an advanced aero-hydro-servo-elastic model of dynamics on the generator-converter dynamics, for an offshore fixed 5MW PMSG wind turbine

This paper gives a comparative analysis of the performance of a wind turbine direct drive train system with PMSG and fully rated converters when two different wind turbine models are used for its assessment. The impact of the advanced Aero-Hydro-Servo-Elastic model, and the most common analytical function wind turbine model, on the generator-converter dynamics are assessed. Results corresponding to the system response to steps up/down in wind speed and turbulent wind speed conditions are presented and discussed in the paper. It is found that below rated speed there is no significant difference between results obtained from both models. Above rated wind speed there exist some differences among results.
