Method according to claim 1, wherein the presence of people on or in the wind power plant (10) is checked after and/or during the safety shutdown of the wind power plant (10). 4. Method according to claim 1, wherein the release of the wind power plant (10) is documented. 5. Method according to claim 1, wherein the wind power plant (10) is released for operation after unlocking of a person-related and/or functional-error-related and/or hardware-related, security code. 6. Method according to claim 1, wherein the operating device (41) is notified after and/or during a safety shutdown of the wind power plant (10). 7. Method according to claim 1, wherein the number of releases of the wind power plant (10) will be or is limited within a predetermined period of time. 8. Energy supply system comprising at least one wind power plant (10), wherein an operating device (41) spatially separated from the wind power plant (10) is provided such that by means of the operating device (41) the wind power plant (10) will be or is released for operation after a safety shutdown triggered by a safety shutdown device that is logically superordinate to the operating control system and wherein a locking device is provided on the wind power plant, wherein upon activation of the locking device a release of the wind power plant will be or is locked by means of the operating device. 9. Energy supply system according to claim 8, wherein the locking device is designed as a service switch. 10. Energy supply system according to claim 8, wherein upon activation of the locking device access of the operating device to the reset function of a safety chain and/or a safety system of the wind power plant will be or is blocked. 11. Wind power plant (10), comprising a locking device provided on the wind power plant (10), wherein upon activation of the locking device a release of the wind power plant (10) will be or is blocked by means of an operating device (41) after a safety shutdown triggered by a safety shutdown device that is logically superordinate to an operating control system and wherein a locking device is provided on the wind power plant, wherein upon activation of the locking device a release of the wind power plant will be or is locked by means of the operating device. 12. Wind power plant (11) according to claim 11, wherein the locking device is designed as a service switch. 13. Wind power plant (10) according to claim 11, wherein upon activation of the locking device access of the operating device (41) to the reset function of a safety chain (20) and/or a safety system of the wind power plant (10) will be or is blocked. 14. Wind power plant (10) according to claim 13, wherein after activation of the locking device the operating device for release of the wind power plant (10) is or will be unlocked after entry of a password or transmission of an authorization. 15. Wind power plant (10) according to claim 13, wherein after activation of the locking device the operating device (41) for the release of the wind power plant (10) is or will be unlocked after checking for the presence or absence of people in and/or on the wind power plant (10) and after the determined absence of people. 16. Wind power plant (10) with a safety chain (20) comprising a reset switch (62), which after the triggering of a safety shutdown of the wind power plant (10), by a safety shutdown device that is logically superordinate to an operating control system, will be or is activated or is activatable by means of or in connection with an operating device (41) that is spatially separated from the wind power plant (10) such that the wind power plant (10) is released for operation after the safety shutdown, wherein at least one manually activatable switch (46.1, 46.2, 46.3, 47) of an emergency shutdown device (NA) is provided, such that after manual activation of the switch (46.1, 46.2, 46.3, 47) a safety shutdown of the wind power plant (10) is triggered. 17. Wind power plant (10) with a safety chain (20) according to claim 16, wherein at least one switch (56.1, 56.2, 56.3) of a safety shutdown device (SA) that is activatable by a sensor is provided, such that after activation of the switch (56.1, 56.2, 56.3) a safety shutdown of the wind power plant (10) is triggered. 18.
