Solution Overview
Problem
Determining the operating space of a gas turbine in real time is challenging due to the difficulty in accurately defining its boundaries, especially when the turbine is online, as existing methods require offline data analysis and separate systems.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If offline data runs and table lookup methods are used to estimate operating space, then the operating space can be determined, but the process requires dedicated offline data analysis and separate offline systems, increasing device complexity and time consumption
Solution Approach 1:
The patent combines the operating space determination function with the existing online control system by integrating a solver that calculates corner points using real-time turbine data. This eliminates the need for separate offline systems and dedicated data analysis infrastructure, resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
The patent transitions from static offline table lookups to dynamic real-time calculations by implementing a solver that continuously computes operating space boundaries based on current turbine operating conditions. This dynamic approach maintains accuracy while eliminating the need for pre-computed offline tables and separate analysis systems
2Measurement precision
If offline data runs are used to estimate operating space, then the operating space boundaries can be identified, but the process requires significant time for offline data analysis, increasing loss of time
Solution Approach 1:
The patent implements preliminary computational setup by formulating the operating space determination as a corner-point solving problem with pre-defined mathematical relationships. This allows the system to perform rapid real-time calculations without requiring time-consuming offline data analysis, resolving the contradiction between measurement precision and loss of time
Solution Approach 2:
The patent replaces the mechanical process of offline data collection, analysis, and table creation with an automated computational solver that directly calculates operating space boundaries using real-time sensor data and mathematical models. This substitution eliminates time-consuming manual or batch processing steps while maintaining boundary accuracy
3Adaptability or versatility
If real-time operating space calculation is implemented, then the system can adapt to changing ambient conditions and provide real-time visualization, but this increases computational requirements and processing complexity
Solution Approach 1:
The patent segments the operating space determination into discrete corner point calculations, where each corner point represents a specific boundary condition. This segmentation allows the complex real-time adaptation problem to be solved through multiple simple, independent calculations rather than one complex computation, reducing overall computational complexity while maintaining real-time adaptability
