The short circuit behavior of the early generation wind turbines depends solely on the physical characteristics of the machine. Conventional protection schemes can be applied to provide protection to those wind farms. But full converter based Type 4 wind turbine generators have complex fault current characteristics governed by the converter controls, with fault current responses very different from synchronous generators. The use of relays with conventional protection and supervision schemes may cause misoperation. This paper presents preliminary concepts for a new protection scheme based on converter control system behavior and tested with simulation of a Type 4 wind turbine in RTDS.
