Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If wind energy generation and solar power generation are used, then environmental pollution and irradiation risk are reduced, but stability of electricity degree and electricity generation quantity are insufficient
Solution Approach 1:
The patent combines multiple energy sources (wind power generator, solar power generator, and conventional generator) into a hybrid power system. The controller intelligently switches between different energy sources based on availability and demand, merging the advantages of renewable energy (environmental friendliness) with conventional energy (stability) to resolve the contradiction between environmental protection and electrical stability.
Solution Approach 2:
The power system is designed with multi-functionality to handle various operating conditions. The same system can operate using wind energy, solar energy, conventional generators, or combinations thereof, depending on environmental conditions and power demand. This universal approach ensures both environmental protection and reliable power supply across different scenarios.
2Object-affected harmful factors
If wind energy generation and solar power generation are used, then environmental protection is improved, but electricity generation quantity is low requiring connection to electric supply
Solution Approach 1:
The system merges renewable energy generation (wind and solar) with conventional power generation capabilities. When renewable energy production is insufficient to meet demand, the conventional generator automatically supplements the power supply, ensuring adequate electricity generation quantity while minimizing reliance on external electric supply and maintaining environmental protection priorities.
Solution Approach 2:
The system includes energy storage units that store electricity generated during periods of high renewable energy production (when wind blows strongly or sun shines brightly) for use during periods of low generation. This preliminary action of storing excess energy ensures continuous adequate power supply without requiring frequent connection to external electric supply.
3Reliability
If conventional electricity generators are operated to supplement battery electricity, then sufficient power supply is achieved, but cost and energy consumption increase
Solution Approach 1:
The controller continuously monitors the electricity levels in the battery, wind power availability, solar power availability, and power demand. Based on this feedback, the controller intelligently decides when to operate the conventional generator, optimizing its operation to provide sufficient power supply only when necessary, thereby minimizing fuel consumption and operational costs while maintaining reliable power supply.
Solution Approach 2:
The power system operates dynamically, adjusting the mix of energy sources based on real-time conditions. The conventional generator's operation is not fixed but dynamically controlled according to battery charge levels, renewable energy availability, and demand requirements, ensuring sufficient power supply while minimizing energy consumption and costs through adaptive operation.
