Convex Polygon Wind Park Layout for Wake Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wind park layouts that minimize wake interference between turbines result in large areas with reduced power production density, making inefficient use of available land and limiting the number of suitable locations for wind farm establishment.
Innovation Solution
A wind park design featuring wind turbines arranged in a convex polygon with node turbines at vertices and intermediate turbines along sides, creating an interior area free of turbines to reduce wake interference while allowing simultaneous operation of turbines on opposing sides, thereby increasing power production without area inefficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If wind turbines are arranged in rows and columns to minimize wake interference, then wake interference between turbines is reduced, but the area occupied by the wind park increases and power production density decreases
Solution Approach 1:
The wind park is segmented into two distinct types of wind turbines: node wind turbines positioned at vertices and intermediate wind turbines positioned along the sides. This segmentation allows for optimized spatial arrangement where node turbines are spaced farther apart to minimize wake interference, while intermediate turbines are positioned to maximize power generation without significantly contributing to wake problems for opposing turbines.
Solution Approach 2:
The patent combines node wind turbines and intermediate wind turbines in a single convex polygon arrangement, merging two different functional roles into one integrated system. The node turbines handle long-range wake management while intermediate turbines maximize local power production, creating a synergistic arrangement that achieves both wake reduction and high power density.
2Object-affected harmful factors
If wind turbines are located at large distances from each other to reduce wake influence, then wake interference is minimized, but the wind park occupies an increasingly large area
Solution Approach 1:
Different spatial arrangements are applied to different parts of the wind park: node wind turbines at vertices are positioned farther apart to minimize wake interference in critical areas, while intermediate wind turbines along sides are positioned closer together to maximize power density in less critical areas where wake interference is naturally reduced by the convex polygon geometry.
3Productivity
If more wind turbines are added to increase power production, then total power output increases, but the number of suitable locations for wind park establishment decreases
Solution Approach 1:
The control system dynamically adjusts which wind turbines are active based on wind direction and other conditions. This dynamic operation allows the same physical arrangement to adapt to varying wind patterns, maximizing power production from the available turbines while the convex polygon geometry ensures that suitable locations can accommodate this flexible arrangement.

AI summary
The present disclosure relates to a wind park (10) comprising wind turbines arranged in a convex polygon comprising straight sides (3, 4, 5) connecting vertices of the polygon. A node wind turbine (1a, 1b, 1c) of a first type is located at each vertex of the polygon. One or more intermediate wind turbine (2a, 2b, 2c, 2d) of a second type is/are located along each side (3, 4, 5) of the polygon between two node wind turbines. The polygon forms an interior area (A) within the sides (3, 4, 5). The interior area (A) is free of turbines of the first and second type.
