Abstract: An electrical system for controlling a wind turbine is provided. The electrical system includes a first resistive element, a storage element and a controller. The first resistive element and the storage element are coupled to a DC link of the wind turbine. The controller is used for switching between the first resistive element and the storage element in response to a grid side fault condition to minimize mechanical loads induced by the grid side fault condition.
