Improvement Transient Stability of Fixed Speed Wind Energy Conversion System by Using Transformer-Type Superconducting Fault Current Limiter

The wind turbine generation system (WTGS) is one of the representative renewable energy systems. With the rapid development of WTGS and its increased capacity, the level of short circuit current will increase in distribution systems. The application of the Superconducting Fault Current Limiter (SFCL), would not only reduce the level of the short circuit current but also offer a reliable interconnection to the network. The transformer-type superconducting fault current limiter (SFCL) is one of the fault current limiters, and has many advantages such as design flexibility. In this paper, the effect of transformer -type SFCL on transient behavior of grid connected to WTGS is studied. The WTGS is considered as a fixed-speed system, equipped with a squirrel-cage induction generator. The drive-train is represented by two-mass model. The simulation results show that the transformer -type SFCL not only limits the fault current but also can improve the dynamic performance of the WTGS.
