Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed yaw control strategy is used, then the control system is simple and easy to operate, but the yaw control effect is poor and wind energy utilization is low
Solution Approach 1:
The patent implements dynamic adjustment of yaw control parameters (initiation angle, stop angle, wait duration, delay duration) based on real-time analysis of wind facing angle time series data and operating duration distribution characteristics. This transforms the fixed strategy into an adaptive system that automatically optimizes parameters according to actual wind conditions, resolving the contradiction between operational simplicity and energy utilization efficiency.
Solution Approach 2:
The system continuously monitors wind facing angle data, analyzes operating duration distributions, and uses this feedback to dynamically adjust yaw control parameters. The feedback loop enables the system to learn from historical data and optimize performance in real-time, improving wind energy utilization while maintaining ease of operation through automated adjustment.
2Device complexity
If a fixed yaw control strategy is used, then the device complexity is low, but the yaw control effectiveness is poor
Solution Approach 1:
The patent introduces dynamic parameter adjustment based on wind facing angle analysis without requiring complex hardware modifications. The system adapts control strategies through software-based analysis of operating duration distributions, achieving improved yaw control effectiveness while maintaining relatively simple device architecture.
Solution Approach 2:
The system performs self-optimization by automatically analyzing its own operating data and adjusting its control parameters accordingly. The yaw control system monitors its performance through wind facing angle measurements and autonomously optimizes initiation angles, stop angles, and timing parameters without external intervention, improving effectiveness while avoiding the complexity of manual tuning systems.
3Productivity
If the yaw control parameters are dynamically adjusted based on data distribution characteristics, then the wind energy utilization is improved, but the control strategy complexity increases
Solution Approach 1:
The patent replaces complex mechanical or manual control adjustment mechanisms with data-driven computational analysis. By using statistical analysis of wind facing angle time series data and operating duration distributions, the system automatically determines optimal parameters, achieving high wind energy utilization through software-based intelligence rather than complex hardware or manual procedures.
