Abstract

A method for the access management of a wind turbine controller of a wind turbine with an operating software. The method comprises receiving a user identification with one of several user interfaces and assigning the user identification or a portion of the user identification to an access group. One or several authorization groups of an overall number of authorization groups is allocated to the access group, and one or several output value storage locations and/or input value storage locations are allocated to each authorization group. The method further encompasses allowing an access from the user interface to all output value storage locations and/or input value storage locations that are allocated to the assigned access group via the authorization groups. The disclosure further relates to a computer product, a wind turbine controller, and a wind turbine with a wind turbine controller.

First claim

The invention claimed is:

1. A method for access management of a wind turbine controller of a wind turbine with an operating software, the method comprising:
receiving, by the wind turbine controller, a user identification using a first user interface of a plurality of user interfaces;
receiving a localization identifier with the user identification, wherein the localization identifier indicates at least whether the first user interface is within the wind turbine or is part of a remote computer via a wind turbine interface, wherein the user identification is allocated to one of a plurality of different access groups as a function of the localization identifier received with the user identification;
assigning, by the wind turbine controller, at least a portion of the user identification to an access group, wherein one or more authorization groups of an overall plurality of authorization groups is allocated to the access group, and wherein one or more output value storage locations or input value storage locations are allocated to each authorization group; and
allowing, by the wind turbine controller, access from the first user interface to all output value storage locations or input value storage locations that are allocated to the assigned access group via the plurality of authorization groups.

2. The method according to claim 1 , wherein the first user interface is within the wind turbine, wherein the localization identifier indicates from which of the plurality of user interfaces in the wind turbine the user identification was received, wherein different localization identifiers are received from a user interface in a tower of the wind turbine and a user interface in a nacelle of the wind turbine.

3. The method according to claim 1 , comprising assigning an active status, wherein the active status is configured to be assigned at any point in time for a single user interface of the plurality of user interfaces, and access, via the first or second user interface, to an input value storage location is permitted only if the operating software of the user interface has assigned the active status.

4. The method according to claim 3 , wherein a respective priority is allocated to each localization identifier, and after a request for an active status has been received from a user interface for a new access, performing a check to determine whether the active status was assigned for another user interface for a previously requested access, and in a case where the active status was assigned to a second user interface of the plurality to user interfaces, the active status is withdrawn from this other user interface if the localization identifier of the user interface for the new access has a higher priority than the localization identifier of the other user interface.

5. The method according to claim 1 , wherein a respective priority is allocated to each access group, and upon receipt of a request for an active status from a user interface, from which a user identification for a new access was received, performing a check to determine whether the active status was assigned for another user interface, and in a case where the active status was assigned, the active status is withdrawn from the other user interface if the access group of the new access allocated to the user identification has a higher priority than the access group of the received user identification from the other user interface.

6. The method according to claim 3 , wherein an active status is withdrawn after the assignment upon expiration of a specific period, or returned through release from a user interface to which the active status is assigned.

7. The method according to claim 1 , wherein the operating software has a plurality of software modules, wherein at least a portion of communications outputs of the software modules are each prepared as an output value storage location, and at least a portion of communications inputs of the software modules are each prepared as an input value storage location.

8. The method according to claim 1 , comprising displaying, on a user interface, data of the output value storage locations that are allocated to the assigned access group via the plurality of authorization groups.

9. The method according to claim 1 , wherein the user interface is used to receive data for the input value storage locations that are allocated to the assigned access group via the plurality of authorization groups.

10. The method according to claim 1 , wherein at least one identical set of output value storage locations and/or input value storage locations is allocated to a plurality of different user groups.

11. A non-transitory computer readable medium that comprises instructions which, when performed on a wind turbine controller, are configured to implement the method according to claim 1 .

12. A wind turbine controller comprising the computer readable storage medium according to claim 11 .

13. A wind turbine comprising a tower, a nacelle, and the wind turbine controller according to claim 12 .

14. The wind turbine according to claim 13 , comprising at least one user interface in the wind turbine, and at least one user interface outside of the wind turbine for access to an operating software of the wind turbine.

15. The wind turbine according to claim 14 , wherein the at least one user interface outside of the wind turbine is a remote computer.
