Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the distributed generation facility transmits power at a fixed voltage determined by the transmission and distribution system, then the power system stability is maintained, but the generation capacity cannot be increased and generation efficiency is low
Solution Approach 1:
The patent applies dynamics by enabling the station transformer to adjust its voltage dynamically based on real-time operating conditions. The tap changer allows the transformer to switch between different voltage levels, transitioning from a fixed voltage system to a dynamic one that can adapt to varying generation capacity requirements while maintaining power system stability through controlled adjustments within allowable voltage ranges.
Solution Approach 2:
The patent implements parameter changes by modifying the voltage parameter of the station transformer. Through the automatic voltage regulator and tap changer, the system changes the voltage level according to the amount of power generation, allowing the distributed generation facility to increase its generation capacity by operating at optimized voltage levels rather than being constrained to a fixed voltage.
2Productivity
If the station transformer voltage is increased to boost generation capacity, then the generation efficiency improves, but the voltage may exceed the allowable range and affect power system stability
Solution Approach 1:
The patent applies feedback through the automatic voltage regulator that continuously monitors the station transformer's output voltage and adjusts the tap changer accordingly. This closed-loop feedback system ensures that the voltage is increased to boost generation capacity while automatically preventing it from exceeding the allowable voltage range, thus maintaining power system stability.
Solution Approach 2:
The system uses dynamic voltage adjustment through the tap changer to balance generation capacity and voltage stability. Rather than using a fixed high voltage that might exceed limits, the system dynamically adapts the voltage level based on real-time conditions, allowing maximum generation capacity within the safe operating voltage range.
