This paper compares the performances of three different Low Voltage Fault Ride- Through (LVFRT) techniques for Wind Energy Conversion Systems (WECS). The comparison aims to identify the most effective technique for alleviation of adverse impacts of AC faults on WECS electrical and mechanical parts, which include DC voltage rise and generator over-speed. The comparison is based on a critical qualitative review of existing literature on the selected LVFRT techniques, which are further supported by quantitative substantiation using simulations. The major findings of this comparative study are highlighted, with emphasis on metrics, which account for practical implementation, hardware, cost, and complexity issues. They are important to assess the overall effectiveness of the techniques evaluated. Although practical and commercial limitations exist, the initial findings suggest that an energy storage solution would be suitable for the enhancement of LVFRT for WECS in future power networks, and if the stored energy is utilised correctly, offer further attractive benefits.
