Modelling and Control of Grid Converter

Project Details


Currently, there is a special focus on the grid code compliance of the new generation of wind turbines/wind farms. Until now the grid connection requirements for the wind turbines were minimal. New grid codes are issued where special requirements regarding voltage Total Harmonic Distortion (THD) levels in the Point of Common Coupling (PCC) as well as the ride-through capabilities during fault events in the grid are specified. Moreover, the new wind turbines/farms must contribute to the regulation of active and reactive power and to contribute to the frequency and voltage control.
The main objectives in this research project are to investigate and evaluate different control algorithms for the grid side converter in a wind turbine system. The harmonics generated by this converter as well as its ride-through capability in case of different fault events in the grid are analyzed.
