Abstract: | The increasing grid integration of wind power has led to the compulsory requirement of low-voltage ride through capability (LVRT) in wind turbines. Grid codes for LVRT capability of wind turbines are proposed in all major wind-energy-producing countries. The testing of LVRT capability compliance of the wind generators as per the specified grid codes during different fault conditions is essential to ensure its reliability. The testing process is generally done by the manufacturers and crucial for certification as per the IEC 61400-21 international standard for measurement of power quality characteristics of wind turbines. This review analyses the various testing tools under the software- and hardware-based categories. The review helps in understanding the present challenges in implementation of wind turbines, to alleviate the difficulty in LVRT testing procedures. |
