Wind Turbine Operating Condition Control via Pre-stored Environmental Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wind power installations face damage risks due to vibrations caused by various environmental conditions such as wind speed, direction, and gustiness, which are not always predictable, making it challenging to prevent damaging operating situations without constant monitoring and complex setting adjustments.
Innovation Solution
A method for setting a wind power installation's operating conditions by storing and selecting specific combinations of environmental conditions and installation settings to avoid hazardous situations, allowing for proactive adjustment of blade angles, rotor position, and azimuth orientation to mitigate vibrations and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If constant monitoring and complex setting adjustments are implemented to avoid damaging operating situations, then the reliability of the wind power installation is improved, but the device complexity and operational difficulty increase
Solution Approach 1:
The patent stores operating situations that should be avoided in advance during the commissioning phase before full operation begins. This preliminary identification and storage of hazardous operating conditions allows the system to avoid them during normal operation without requiring complex real-time monitoring and analysis, thereby improving reliability while reducing operational complexity
Solution Approach 2:
The patent creates a database of stored operating situations that should be avoided, which serves as a reference copy for future operations. Instead of continuously analyzing complex environmental conditions in real-time, the system compares current conditions against this pre-stored reference data, simplifying the monitoring process while maintaining high reliability
2Reliability
If constant monitoring and real-time setting adjustments are made to respond to detected vibrations, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent performs the complex analysis and identification of hazardous operating situations during the commissioning phase before full operation begins. By completing this preliminary action in advance, the system avoids the need for complex real-time setting adjustments during normal operation, thereby improving reliability while maintaining ease of operation
Solution Approach 2:
The system uses pre-stored operating situations as a self-service reference during normal operation. Instead of requiring complex real-time analysis and manual intervention, the system automatically compares current conditions against the pre-stored data and can independently determine appropriate settings, simplifying operation while maintaining reliability

AI summary
A method for setting a fully or partially built wind power installation having a rotor having a plurality of rotor blades whose blade angle can be adjusted, wherein the wind power installation can take on variable operating situations, and each operating situation is characterized by a combination of settable installation settings of the wind power installation and environmental conditions that can be captured, with the result that an operating situation can be set for given environmental conditions by setting the installation settings, and operating situations that should be avoided and/or suitable operating situations are stored in a memory by storing a combination of environmental conditions and installation settings as a combination to be avoided for an operating situation that should be avoided in each case, and/or storing a combination of environmental conditions and installation settings as a suitable combination for a suitable operating situation in each case, and, to avoid operating situations that should be avoided, environmental conditions are captured and, depending on the captured environmental conditions and the stored combinations to be avoided and/or suitable combinations, installation settings of the wind power installation are selected and set such that installation settings of stored combinations to be avoided are avoided, and/or installation settings are selected from stored suitable combinations.
