Control of the grid side converter in a wind turbine during grid faults

Due to constantly increasing share of wind power in total installed power, transmission system operators must adhere to ever stricter grid codes in order to maintain stable, secure and reliable power system operation. Grid codes in most of the countries with significant share of wind power require from wind power plants to participate in active and reactive power control, to stay connected to the grid during grid faults, as well as to provide voltage support to the grid during voltage sags. In this paper, a wind turbine grid side converter control system is proposed which enables the wind turbine to obey even the strictest requirements. Simulations are carried out in order to validate the proposed control system.
