Engineering Contradiction Analysis
1Area of stationary object
If floating wind turbines are positioned closely in a wind park to increase sea area utilization, then the available sea area for wind energy production is increased, but wake effects become more complex and reduce power production due to dynamic motions
Solution Approach 1:
The patent applies dynamics by making the wind turbine position adjustable rather than fixed. The floating wind turbine can change its position during operation to optimize wake control, adapting to varying wind conditions and reducing wake effects on downstream turbines while maintaining high sea area utilization
Solution Approach 2:
The patent changes the position parameter of the floating wind turbine dynamically. By adjusting the turbine's position based on monitored wind conditions and floating motion states, the system optimizes power production while minimizing wake effects in densely packed wind parks
2Ease of manufacture
If conventional wake control methods are used in floating wind parks, then implementation is simpler, but wake effects cannot be effectively reduced due to complex dynamics from floating motion
Solution Approach 1:
The patent implements feedback control by monitoring wind conditions and floating motion states in real-time, then using this information to dynamically adjust turbine position. This closed-loop approach effectively reduces wake effects while accounting for the complex dynamics of floating motion
Solution Approach 2:
The floating wind turbine uses its own motion characteristics and environmental interactions to its advantage. The natural floating motion is utilized as part of the wake control mechanism, reducing the need for complex external control systems while still achieving effective wake management
3Productivity
If downstream wind turbines are positioned to avoid wake effects, then power production increases, but the wind park layout becomes less efficient in terms of sea area utilization
Solution Approach 1:
Instead of using static positioning to avoid wake effects, the patent employs dynamic position adjustment. The floating wind turbine can move to optimal positions that reduce wake exposure while maintaining efficient packing density, achieving both high power production and effective sea area utilization
