The transient behavior of the 2 MW wind turbine under a symmetrical 3-phase voltage dip with zero remaining voltage and unsymmetrical phase-to-phase disturbance with 20 % residual voltage is experimentally studied. The results of the voltage dip tests are compared with simulation study. The comparison of the results shows close agreement; therefore validated simulation model is suitable for performing wind turbine voltage dip test simulations without a need to make the site tests. The developed model is also suitable for accurate transient simulation of the small wind park with reduced number of wind turbines. Additionally it can be used as a reference model for the optimization and verification of the simplified turbine model used in power system analysis software.
