Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wind power plants maintain constant active power within one period to ensure grid stability, then grid reliability is improved, but the ability to rapidly regulate active power according to consumption capability deteriorates
Solution Approach 1:
The patent divides the control period into multiple sub-periods, allowing active power to be dynamically adjusted at each sub-period boundary based on real-time consumption capability monitoring. This transforms the static constant power control into a dynamic multi-stage control process, enabling both grid stability and rapid regulation response.
2Ease of operation
If wind power plants operate with constant active power output, then control simplicity is maintained, but power generation capability utilization deteriorates
Solution Approach 1:
The patent segments the wind power plant cluster into multiple priority groups and divides the control period into multiple sub-periods. This segmentation allows different subsets of wind power plants to operate at different power levels in different sub-periods, maximizing overall power generation capability while maintaining relatively simple control logic within each segment.
3Device complexity
If wind power plants operate without considering power generation sequence, then operational complexity is reduced, but power generation capability utilization deteriorates
Solution Approach 1:
The patent assigns different priority levels to different wind power plants based on their power generation characteristics and grid requirements. Each priority group receives differentiated control instructions, allowing the system to optimize power generation capability by treating different plants differently rather than applying uniform control to all plants.
