+Power production with fault (2.X)
+---------------------------------
+DLCs 2.X involves cases where faults turbine and/or loss of electrical network connection occurs while the turbine is producing power and connected to an electircal load.
+In additions to the options used to describe power production, DLC 2.X allow foroptions to descibe blade pitch, generator and yaw faults.
+The azimuth position for the rotor at the time of a fault may have significant influence on the load levels.
+Therefore, the `azimuth_init` is required for DLC 2.X.

+DLC 2.1

+DLC 2.1 related to normal control system fault or loss of electrical network.
+The faults included in this DLC are: blade pitch fault, yaw position fault and, loss of electrical network.
