Abstract:
A pitch system of a wind energy system includes an emergency energy store for moving a rotor blade into a safety position in the event of the failure of an external energy supply. The emergency energy store can be tested, for example to assess aging, by supplying electrical energy to an actuating device configured to set a pitch angle of a rotor blade even in a normal operating mode of the wind energy system temporarily exclusively from the emergency energy store. This configuration ensures reliable operation of a wind energy system.
