Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple circuit breakers are installed in wind turbine systems to manage current paths and interconnections, then the reliability of current interruption is improved, but the device complexity increases
Solution Approach 1:
The electrical power transmission system is segmented into three separate electrical power transmission modules, each with its own circuit breaker. This segmentation allows independent control and interruption of different current paths, improving reliability while maintaining manageable complexity through modular design.
Solution Approach 2:
Each electrical power transmission module is designed to perform multiple functions: it can transmit power from the generator, interconnect with other wind turbines, and provide independent circuit interruption. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall system complexity while maintaining high reliability.
2Reliability
If three electrical power transmission modules with circuit breakers are used to enable reliable current interruption and interconnection, then the reliability and operational continuity are improved, but the device complexity and space requirements increase
Solution Approach 1:
Multiple electrical power transmission modules are merged into a single integrated system with a common busbar structure. This merging allows the modules to share common components and space, reducing overall system complexity and footprint while maintaining the reliability benefits of having multiple independent circuit breakers.
Solution Approach 2:
The electrical power transmission modules are arranged in a compact, nested configuration where modules are positioned adjacent to each other around the busbar. This nesting approach maximizes space utilization within the tower structure, reducing the space requirements despite having multiple modules with circuit breakers.
3Reliability
If electrical power transmission modules are arranged side by side with interconnected housing parts for gas-tight encapsulation, then the reliability of gas-insulated current paths is improved, but the manufacturing complexity increases
Solution Approach 1:
The gas-tight encapsulation is segmented into separate housing parts for each electrical power transmission module. Each module has its own first housing part that can be manufactured and assembled independently, then interconnected with adjacent modules. This segmentation simplifies manufacturing compared to creating a single large gas-tight enclosure.
Solution Approach 2:
The housing parts of adjacent electrical power transmission modules are interconnected to form a continuous gas-tight enclosure for the busbar and current paths. This merging of separate modular housing parts achieves the required gas-tight encapsulation while maintaining the manufacturing advantages of modular construction.
