Wind Farm Software Update Staging for Safe Remote Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software updates for wind farm components like wind turbines are complex, require significant intervention, and must be carefully planned to avoid unpredictable operating situations, often necessitating the presence of trained service technicians and lengthy service calls due to slow data connections.
Innovation Solution
A centralized update system outside the wind farm compiles and transfers tailored software update packages to units via an external data link, allowing automated updates with on-site approval, reducing the need for physical intervention and ensuring safety by waiting for confirmation before execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software updates are performed manually by service technicians, then safety and reliability are improved, but time consumption and operational disruption increase
Solution Approach 1:
The system prepares update packages in advance and transfers them to the wind turbine before the actual update execution. The package is staged in a safe state, allowing the turbine to be updated without requiring continuous technician presence or causing operational disruption. This separates the preparation phase from the execution phase, improving both safety and time efficiency.
Solution Approach 2:
The wind turbine system performs self-verification of update packages using cryptographic signatures and hash values without requiring external validation. The turbine can autonomously execute updates after verifying package integrity, reducing dependency on technician intervention while maintaining safety through automated verification mechanisms.
2Loss of information
If update packages are transferred during service calls, then data availability is improved, but service call duration and cost increase
Solution Approach 1:
Update packages are transferred to the wind turbine in advance during scheduled maintenance windows or off-peak periods, rather than during critical service calls. The system stores these packages locally and executes updates when conditions are favorable, separating data transfer from critical operational interventions and improving overall service efficiency.
Solution Approach 2:
The system uses an intermediary storage mechanism (local storage on the wind turbine) to decouple the update package transfer from the update execution. This allows packages to be transferred asynchronously without requiring synchronous coordination between technicians and the turbine system, reducing service call duration.
3Productivity
If multiple units are updated simultaneously, then overall update efficiency is improved, but coordination complexity and risk increase
Solution Approach 1:
The system segments the wind farm into multiple units, each with independent update capability. Update packages are divided into unit-specific portions, and each unit can be updated independently according to its own readiness and operational conditions. This segmentation allows parallel updates while maintaining manageable coordination complexity through modular architecture.
Solution Approach 2:
The update system implements a universal package structure that can be applied across multiple different wind turbine units. A single update package format serves multiple units with different configurations, simplifying the coordination process while enabling efficient batch updates across the entire wind farm.

AI summary
The invention relates to a method for updating at least one unit (22), in particular a wind turbine (100), or at least one of several wind farms (14), with an update device arranged outside the wind farm (14), wherein the update device is configured to establish a data connection with several wind farms (14). The method comprises providing a database (34), receiving a selection of at least one unit (22) from the database (34) by the update device, compiling a package for the wind farm (14), and transmitting the package from the update device to the wind farm (14) containing the selected unit (22).The method further comprises outputting information after completion of the transmission by the update device, waiting for the receipt of authorization to execute the update, executing the update after receiving authorization, receiving confirmation of a successful update, and storing an indicator of the successful update in the database (34). The invention further relates to a system (10) for updating at least one unit (22) of a wind farm (14).
