1. A method for controlling a wind turbine connected to a utility grid, the method comprising:
- detecting a fault of the utility grid; and
in response to detection of the fault, controlling a pitch of one or more rotor blades of a rotor of the wind turbine in a fault mode to stabilize a speed of the rotor between a first value rated for the rotor of the wind turbine and a second value at which a generator of the wind turbine is tripped offline from the utility grid.

Abstract
The invention relates to a method for controlling a wind turbine connected to the utility grid comprising steps of detecting a fault of the utility grid, and controlling one or more rotor blades in a fault mode wherein said one or more rotor blades are pitched in order to stabilize the rotor speed within an over speed range. The invention also relates to a wind turbine and a wind park comprising at least two wind turbines.
