Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If gas generators are used to provide power on offshore oil and gas platforms, then power supply is ensured, but carbon emissions and operating costs increase
Solution Approach 1:
The patent combines gas generators with offshore wind power to form a hybrid power system. The wind power is integrated into the existing gas generator-based power system, allowing the two different power sources to work together. This merging enables the system to utilize renewable wind energy while maintaining the reliability of gas generators, thereby reducing carbon emissions without compromising power supply stability.
Solution Approach 2:
The gas generators in the patent serve multiple functions: they provide base load power, compensate for wind power fluctuations, and ensure power supply reliability. By making the gas generators multi-functional, the system can accommodate variable wind power while maintaining stable power supply, thus reducing emissions without sacrificing reliability.
2Object-affected harmful factors
If wind power is integrated with gas generators for parallel operation, then fuel cost and carbon emissions are reduced, but system complexity and control difficulty increase
Solution Approach 1:
The patent implements a scheduling system that monitors wind power output and gas generator performance in real-time. Based on this feedback, the system dynamically adjusts the operating parameters of gas generators to compensate for wind power fluctuations. This feedback mechanism enables automatic coordination between the two power sources, reducing the need for complex manual control while managing system complexity.
Solution Approach 2:
The patent employs dynamic scheduling strategies that adapt to changing wind conditions. The gas generator operating points are continuously adjusted based on real-time wind power output, allowing the system to respond dynamically to variability. This dynamic approach simplifies control by using flexible, adaptive strategies rather than rigid, complex control systems.
3Object-affected harmful factors
If gas generators operate at lower power to reduce carbon emissions, then environmental impact decreases, but the ability to cope with wind power fluctuations and maintain system stability deteriorates
Solution Approach 1:
The patent changes the operating parameters of gas generators dynamically based on wind power conditions. Instead of operating at a fixed low power level, the gas generators adjust their output parameters in response to wind fluctuations. This parameter change strategy allows the system to maintain lower average emissions while preserving the ability to respond to wind variability when needed.

AI summary
A wind power accommodation oriented low-carbon operation scheduling method for offshore oil and gas platform energy system. Aiming at uncertainty and fluctuation of wind power, the method constructs a target linear planning model. A target function result of the model is the lowest power synthesis of a gas generator. Constraints of the model include a gas power generation and wind power synergetic ramp flexibility constraint, a gas generating capacity and wind power capacity synergetic flexibility constraint, an operating characteristic constraint of a gas generator set, an operating characteristic constraint of a gas compressor and a grid-connected operating characteristic constraint of a wind generator. The scheduling method can effectively cope with the uncertainty and fluctuation of wind power, so as to reduce carbon emission of the energy system of the offshore oil and gas field.
