Engineering Contradiction Analysis
1Measurement precision
If manual conversion and adjustment of parameters is performed for dynamic simulation, then simulation accuracy can be maintained, but processing time increases and labor requirements increase
Solution Approach 1:
The system performs preliminary conversion of static model parameters into dynamic model parameters before the actual dynamic simulation. The parameter conversion unit automatically converts parameters from the static model to the dynamic model based on predetermined conversion rules, preparing all necessary parameters in advance so that the dynamic simulation can proceed without manual intervention and time loss.
2Measurement precision
If manual conversion and adjustment of parameters is performed for dynamic simulation, then simulation accuracy can be maintained, but labor requirements increase
Solution Approach 1:
The system enables self-service by automatically performing the parameter conversion process without requiring skilled operators. The parameter conversion unit autonomously converts static model parameters to dynamic model parameters using predetermined conversion rules, eliminating the need for manual intervention and reducing labor requirements while maintaining conversion accuracy.
3Measurement precision
If skilled operators are used to operate the plant on the dynamic simulator, then accurate simulation results can be obtained, but the system becomes less accessible and more expensive
Solution Approach 1:
The system introduces an intermediary parameter conversion unit that automatically handles the complex parameter conversion process between static and dynamic models. This intermediary component bridges the gap between simple static model input and complex dynamic simulation requirements, eliminating the need for skilled operators to manually perform conversions while ensuring accurate parameter transformation.
4Adaptability or versatility
If the scale of the plant is increased, then more comprehensive simulation coverage is achieved, but processing time increases
Solution Approach 1:
For large-scale plants with comprehensive simulation coverage requirements, the system performs preliminary parameter conversion for all plant components and subsystems before the actual dynamic simulation. The parameter conversion unit automatically processes all parameters across the entire plant scale, preparing conversion results in advance so that the subsequent dynamic simulation can efficiently process large-scale data without proportional time increases.
