Wind Turbine Instruction Queue for Secure Autonomous Fetching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wind power plants face security risks and operational inefficiencies when receiving digital instructions from external parties, as disconnecting the connection can lead to reduced energy production, increased risk of wear, and malfunctioning.
Innovation Solution
A method where instructions for controlling a wind power plant are stored in an external digital storage device and fetched independently within the private network, allowing secure and autonomous retrieval without external influence, including validation and authentication steps to ensure only trusted instructions are executed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connection for conveying digital information is established to obtain instructions from external parties, then the power plant can receive control instructions from external parties, but security risks increase
Solution Approach 1:
The system segments the instruction retrieval process into two distinct parts: (1) external storage of instructions in a queue at the network boundary, and (2) internal autonomous fetching by devices within the private network. This segmentation allows the power plant to access external instructions without establishing continuous external connections, thereby reducing security risks while maintaining adaptability.
Solution Approach 2:
The patent introduces an intermediary mechanism - the instruction queue located at the network boundary - that mediates between external instruction sources and internal power plant systems. Devices within the private network fetch instructions autonomously from this intermediary queue, eliminating the need for direct external connections while enabling instruction retrieval.
2Object-affected harmful factors
If the connection for conveying digital information is disconnected to eliminate security risks, then security risk is reduced, but energy production decreases and operational efficiency deteriorates
Solution Approach 1:
Devices within the private network perform self-service by autonomously fetching instructions from the external queue based on their own operational needs and timing. This eliminates dependency on external connections for instruction retrieval, allowing the power plant to disconnect from external networks while maintaining full operational capability and productivity.
3Object-affected harmful factors
If instructions are fetched autonomously and independently within the private network, then security risk is reduced, but system complexity increases
Solution Approach 1:
Instructions are prepared and stored in advance in an external queue before being needed by internal devices. This preliminary action allows devices to simply fetch pre-prepared instructions autonomously without requiring complex real-time communication protocols or decision-making mechanisms, thereby limiting complexity while achieving security goals.

AI summary
Obtaining within a private network of a power plant one or more instructions for controlling the power plant, wherein the power plant includes one or more wind turbine generators, and wherein one or more instructions for controlling the power plant are received at an external digital storage device placed externally with respect to the private network. The one or more instructions are stored in a queue in the external digital storage device. The one or more instructions are fetched from the queue independent with respect to events initiated externally with respect to the private network.
