Wind Plant Short-Circuit Contributions

Wind plant electrical system designers and protection engineers have to take into consideration the characteristics of wind turbine generators when determining short-circuit duties of equipment and protective relay settings. Because of the wide range of commercially-available generators and limitations on available information due to proprietary issues, it is often necessary to make broad assumptions on the behavior of generators during faults and their short- circuit current contributions. This session is designed to provide attendees with a broad background on the types of wind turbine generators, their design, short-circuit characteristics, modeling, and model validation. Several different wind turbine generator manufacturers will participate in this session. An overview of considerations for wind plant system design and power system protection issues will also be presented.
