Claim:
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 ( 1 , 2 A, 2 B, 2 C, 2 D, 3 , 4 ), depending on the control tasks they must perform, b) during the operation of the wind energy park, the control units ( 1 , 2 A, 2 B, 2 C, 2 D, 3 , 4 ) communicate continuously with each other and/or with a central communication unit ( 15 ), c) in case that there is a failure of a first control unit ( 1 , 2 A, 2 B, 2 C, 2 D, 3 , 4 ) of the wind energy park, a second control unit ( 1 , 2 A, 2 B, 2 C, 2 D, 3 , 4 ) of the wind energy park takes over the control tasks of the defective ( 1 , 2 A, 2 B, 2 C, 2 D, 3 , 4 ) 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 ( 1 , 2 A, 2 B, 2 C, 2 D, 3 , 4 ) control unit, and d) in case of a failure of a wind energy plant a first control unit that had been controlling it is assigned to a wind energy slant whose control unit has a failure.
