Fault ride through strategy of DFIG using rotor voltage direct compensation control under voltage phase angle jump

Wind power has developed rapidly in recent years, and large-scale wind power facilities connected to power grids will bring many new challenges. Some new operation characteristics of power grids with doubly-fed induction generator (DFIG) may exhibit, for example voltage phase angle jumps (VPAJ). VPA...

Description
Summary:Wind power has developed rapidly in recent years, and large-scale wind power facilities connected to power grids will bring many new challenges. Some new operation characteristics of power grids with doubly-fed induction generator (DFIG) may exhibit, for example voltage phase angle jumps (VPAJ). VPAJ can negatively impact the fault ride through (FRT) performance of DFIG. This paper firstly investigates the physical mechanism and the operation characteristics of DFIG with VPAJ. It is noted that the current control strategies designed for voltage amplitude changes are not suitable for VPAJ. Secondly, the paper develops an FRT optimization control strategy under VPAJ which optimizes the DFIG operation characteristics. Finally, simulations of a 250 MW wind farm are presented which validate the proposed FRT strategy.
