Patent Images
1. A control system for a wind turbine, comprising:
- an electrical device that is arranged for being used during normal operation of a wind turbine; and
a power source that is arranged to be used as an emergency power supply to said electrical device,wherein the electrical device is a blade pitch motor for adjusting a pitch of a rotor blade of the wind turbine,wherein the power source is configured to supply a current to the blade pitch motor so that the blade pitch motor tests at least one property of the power source, the current being insufficient to cause a pitch movement of the rotor blade.
