Abstract: Especially during grid faults, grid code requirements for wind power integration have become a key element in improving grid efficiency and reliability. Under severe network operation problems, wind turbines are expected to continue operating and supporting the grid during frequency restoration. This paper presents simulation results of a fixed-speed gridconnected wind turbine under various short-circuit current contributions. Fault analysis is carried out by studying the gridside line-to-ground fault, double-line fault, double-line-to-ground fault, and three-phase fault involving ground and without ground. The obtained current waveforms are analysed to explain their behaviour, including the rate of decay and peak values. Variations of active and reactive power during post-fault conditions and faulty conditions are investigated. Moreover, recommendations for switchgear and protection equipment are provided.
