Abstract
The present invention is related to a method for controlling a wind energy plant with plural control units, which perform control tasks in the wind energy plant, 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 plant, the control units communicate continuously with each other and/or with a central communication unit, c) in case that there is a failure of a first control unit of the wind energy plant, a second control unit of the wind energy plant 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.

A method for controlling a wind energy plant with plural control units which perform control tasks in the wind energy plant, comprising the following steps:
- a) one priority at a time is assigned to the plural control units, depending on the control tasks they must perform,
- b) during the operation of the wind energy plant, the plural control units communicate continuously with each other and with a central communication unit,
- c) in case that there is a failure of a first control unit of the plural control units of the wind energy plant, a second control unit of the plural control units of the wind energy plant takes over the control tasks of the defective first 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.
A method for controlling a wind energy plant with plural control units which perform control tasks in the wind energy plant, comprising the following steps:
- a) during the operation of the wind energy plant, the plural control units communicate continuously with each other and with a central communication unit,
- b) in case that a failure of a first control unit of the plural control units of the wind energy plant takes place, a second control unit of the plural control units of the wind energy plant, which has performed its own control tasks before, takes over the control tasks of the defective first control unit, wherein the second control unit is selected depending on whether it has sufficient capacity for performing the control tasks of the defective first control unit in addition to its owns control tasks, and subsequently, the second control unit performs its own control tasks as well as the control tasks of the defective first control unit.

- a) one priority at a time is assigned to the plural control units, depending on the control tasks they must perform,
- b) during the operation of the wind energy plant, the plural control units communicate continuously with each other and with a central communication unit,
- c) in case that there is a failure of a first control unit of the plural control units of the wind energy plant, a second control unit of the plural control units of the wind energy plant takes over the control tasks of the defective first 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, and
- further characterised in that the control units retrieves a control program for performing the control tasks of another control unit from a central communication unit according to necessity, before taking over the control tasks of the other control unit.
