Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reactive power is compensated without considering loading state, then compensation is performed continuously, but optimization of compensation depending on loading state becomes impossible
Solution Approach 1:
The patent implements dynamic compensation by switching between different compensation modes (power factor compensation and flicker compensation) based on the loading state. The system dynamically adjusts the compensation strategy: when no load is present, it performs power factor compensation; when load is present, it performs flicker compensation. This dynamic adaptation resolves the contradiction between continuous compensation and loading-state optimization.
Solution Approach 2:
The patent changes the compensation parameter based on loading state detection. The control system detects whether a load is input and switches the compensation mode accordingly: using power factor compensation mode when load is not input, and flicker compensation mode when load is input. This parameter change enables optimization of compensation depending on loading state.
2Device complexity
If simple reactive power compensation is performed, then system complexity is reduced, but power factor improvement and flicker management efficiency deteriorate
Solution Approach 1:
The patent employs feedback control by detecting the loading state and using this information to switch compensation modes. The control system continuously monitors whether a load is input and adjusts the compensation strategy accordingly, providing feedback-based optimization of power factor and flicker management without significantly increasing system complexity.
Solution Approach 2:
The patent makes the reactive power compensation system multi-functional by enabling it to perform both power factor compensation and flicker compensation using the same hardware infrastructure. The system universally handles different compensation needs based on loading state, improving efficiency without proportionally increasing device complexity.
