Transient Operation of a Hybrid Wind Farm With FSIG and PMSG

A novel control strategy for a hybrid wind farm comprising of both the permanent magnet synchronous generator (PMSG) and fixed speed induction generator (FSIG) under a symmetrical grid fault is proposed in this research work. With a coordinated control of the hybrid wind farm, the proposed strategy seeks to provide maximum reactive power support to the FSIG and improve the recovery of the grid during the symmetrical grid fault by utilizing the operational characteristics of the PMSG. This invariably improves the output power quality and performance of the FSIG without the need for extra communication equipment between the different wind power generators.
