ABSTRACT:
The present invention is related to a method for controlling a wind energy park with plural wind energy plants and plural control units, which perform control tasks in the wind energy park, comprising the following steps:a) one priority at a time is assigned to the control units, depending on the control tasks they must perform,b) during the operation of the wind energy park, the control units communicate continuously with each other and/or with a central communication unit,c) in case that a failure of a first control unit of the wind energy park takes place, a second control unit of the wind energy park takes over the control tasks of the defective control unit, wherein the second control unit is selected depending on the priority assigned thereto and has the same as or a lower priority than the defective control unit.
