Control of Wind Turbines with Induction Generators Interfaced to the Grid with Power Electronics Converters

An electrical system for wind turbines using cage induction generator with back to back converters for connection to the network is experimentally tested under voltage sags in a 55 kW generator set-up. Standard vector control techniques are implemented with the aim to maintain balance between generated power and power supplied to the grid. The robustness of the power electronics converter is experimentally analyzed under short circuit conditions and the converters are found to be robust against voltage sags.
