Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current substation construction practices involve designing custom solutions for each wind farm, leading to high costs and limited scalability, while integrating substations into wind turbine foundations complicates structural integrity and increases mass, limiting their applicability.
Innovation Solution
A wind farm electrical substation composed of standardized unit modules, each with identical shape and dimensions, capable of withstanding various stresses and accommodating all necessary equipment, allowing for mass production and flexible installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom-designed substations are built for each wind farm, then specific performance requirements are met, but construction costs increase and scalability is limited
Solution Approach 1:
The substation is divided into multiple identical modular units, each comprising a transformer and associated equipment housed in standardized containers. These modules can be independently manufactured, tested, and assembled on-site, enabling standardized production while meeting specific performance requirements through selective module configuration.
Solution Approach 2:
The patent creates universal modular units that can serve multiple wind farms with different power requirements. Each module is designed with standardized dimensions and interfaces, allowing the same basic unit to be deployed in various configurations (1x, 2x, 3x modules) to meet different performance specifications without requiring custom design for each installation.
2Ease of manufacture
If substations are integrated into wind turbine foundations, then additional foundation construction is eliminated, but structural mass increases and structural integrity becomes more complex
Solution Approach 1:
The substation is segmented into transportable modular units that rest on the seabed or on separate foundations, rather than being integrated into the wind turbine foundation. This separation allows the turbine foundation to maintain its optimized structural design without additional mass from substation equipment.
3Ease of manufacture
If standardized modules are used for substations, then mass production and cost reduction are enabled, but adaptability to different power requirements is limited
Solution Approach 1:
The substation capacity is segmented into discrete modular units that can be combined in different quantities (1 module, 2 modules, 3 modules, etc.) to achieve various total power ratings. This modular approach enables standardized manufacturing of each unit while providing flexible adaptation to different wind farm power requirements through simple replication and assembly.
