Wind Farm Access Control via Certification Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access authorization methods for wind energy installations and wind farms are vulnerable to human error and sabotage, as users with knowledge of access data can inadvertently or intentionally shut down multiple wind farms, leading to potential energy network failures.
Innovation Solution
A method involving a certification body that authenticates users and issues digital certificates for control access, ensuring that only authorized users can perform critical operations, with access types and validity periods managed centrally to prevent network instability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users are granted control access to wind farms using traditional authentication methods, then operational flexibility and ease of access are improved, but security vulnerabilities increase allowing unauthorized shutdowns and network failures
Solution Approach 1:
The patent introduces a certification body as an intermediary between users and wind farms. This certification body issues digital certificates that authenticate user identities and authorize control accesses. The certification body acts as a trusted mediator that verifies user credentials and manages access rights, preventing direct unauthorized access to wind farms while maintaining operational flexibility for legitimate users.
2Reliability
If digital certificates are implemented for user authentication, then system security is improved, but device complexity increases due to additional authentication infrastructure
Solution Approach 1:
The patent extracts the authentication functionality from the wind farm control systems and places it in a separate certification body. The certification body handles all authentication operations by issuing and managing digital certificates, while wind farms only need to verify these certificates. This separation reduces the complexity burden on individual wind farm systems while maintaining strong security through centralized authentication management.

AI summary
The invention relates to a method for authorizing a user (18) for control access to at least one wind power installation (100) or at least one wind farm. In this case, a user (18) is first of all authenticated by a certification centre (10) and a type of control access is accepted from the authenticated user (18) by the certification centre (10). An electronic certificate (28) is then produced using the certification centre (10) on the basis of the accepted type of control access and/or stored access rights of the authenticated user (18). Authentication with the certificate (28) then takes place at the wind power installation (100) or the wind farm for the purpose of performing control access. In addition, the invention relates to a system for carrying out the method and also to an interface for a wind power installation or for a wind farm and to a certification centre.
