Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static computer models are used for electrical power systems, then system design and simulation can be performed offline, but the models cannot adjust to daily operational changes or age with the facility, leading to inaccurate reliability predictions
Solution Approach 1:
The patent transforms static computer models into dynamic models that automatically update themselves in real-time. The system continuously synchronizes the virtual electrical power system with actual operational data from sensors, allowing the model to adapt to daily changes in system configuration, load conditions, and component aging without manual intervention. This dynamic updating capability enables accurate reliability predictions that reflect current system state.
Solution Approach 2:
The patent implements a feedback mechanism where real-time operational data from the physical electrical power system is continuously fed back to update the virtual model. Sensors monitor actual system parameters and feed this information back to the computer model, which then automatically adjusts its state to match the physical system. This closed-loop feedback ensures the model remains synchronized with actual operational conditions.
2Reliability
If detailed redundancy layers are designed into mission critical electrical systems, then power availability is ensured, but system complexity increases significantly
Solution Approach 1:
The patent creates a virtual copy of the physical electrical power system that mirrors its topology, components, and operational state. This virtual model allows operators to analyze system behavior, test scenarios, and assess reliability without interfering with the actual complex physical system. The copy enables simplified monitoring and analysis while the physical system maintains its necessary redundancy for power availability.
Solution Approach 2:
The patent segments the complex electrical power system into discrete, manageable components represented in the virtual model. Each component (generators, transformers, breakers, loads) is individually modeled and can be independently analyzed. This segmentation allows the complex system to be understood and managed through its constituent parts while maintaining the overall system's reliability through coordinated operation.
3Measurement precision
If traditional transient stability programs are used, then accurate computation of power system trajectories is achieved, but the understanding of disturbance severity and system security is left to engineer judgment
Solution Approach 1:
The patent introduces an intelligent intermediary layer between the traditional transient stability computation and the engineer. This layer automatically analyzes the computed trajectories, compares them against predefined security criteria, and provides interpreted results regarding disturbance severity and system security. The intermediary translates complex computational outputs into actionable insights, reducing reliance on subjective engineer judgment while maintaining computational accuracy.
