Analysis of compensation techniques applied to the control of converter connected synchronous wind turbines and DFIG´s during grid disturbances

This paper investigates control schemes to improve the performance of converter connected synchronous generators and DFIG´s to grid voltage unbalance and grid faults. Both the synchronous generator with a full converter and a DFIG are modelled in Matlab/Simulink. The control schemes of both turbines are modified to improve their performance during grid disturbances including grid voltage unbalance and single-phase faults. These disturbances are introduced into the models at specific times to analyse the performance of the wind generation systems. The performances of both systems to the grid disturbances are compared and the results are analysed.
