The definition of standard dynamic wind turbine models for power system stability analysis has been under development in recent years. These standard models, also known as generic or simplified models, have been developed under the framework of a new international standard, IEC 61400-27-1, the first edition of which was published in February 2015. These models are simplified representations of complex systems, such as wind turbines. Hence, the wind power industry urgently needs validation in comparison with real measurements to verify the accuracy and corresponding usability of the models. This paper presents the validation of a generic doubly-fed induction machine wind turbine model, commonly known as Type 3, based on a measurement campaign carried out in a Spanish wind farm. The wind turbine has been subjected to six voltage dips with different characteristics, magnitude, and duration, as well as several wind turbine operating conditions. The real behavior of the wind turbine is compared with the simulated response provided by the corresponding generic dynamic wind turbine model produced by the manufacturer Gamesa. Furthermore, the validation guidelines recently issued by IEC 61400-27-1 have been implemented, and the most important validation errors have been analyzed.
