Resumé

When performing short-circuit investigations in power systems including wind power, valuable and accurate results can only be obtained by considering the real behavior of wind turbines which is specified in national grid codes. This requires the consideration of the exact active and reactive current injections during the fault. In this paper an equivalent VSC-based wind turbine model for short-circuit calculations at steady-state conditions is developed and presented. The model is implemented in DigSILENT PowerFactory using the DPL-Programming Language. The developed wind turbine model is successfully evaluated proving that the DPL routine accurately implements the injection of the desired active and reactive current components according to the German grid code; the model is also compared with the validated 3.6MW variable-speed wind turbine dynamic model developed and provided by Siemens Wind Power. The wind turbine model is finally rescaled to obtain an aggregate wind farm model and used to perform short-circuit calculations in a realistic scenario; the Danish transmission system is considered and a large offshore wind farm with VSC-based wind turbines is included in the investigation.
