Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The startup of power generation units is a time-consuming process, and while accelerating this startup can provide economic benefits, it poses a risk of equipment damage due to over-stressing. There is a need for a method to accurately calculate and optimize the start and end times of each phase to balance efficiency and safety.
Innovation Solution
A system comprising computing devices and plant historians that collect and analyze operational data to determine the start and end times of startup phases in power generation units, using predefined conditions and rules to evaluate the data and generate reports for optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the startup process is accelerated to make power available more quickly, then productivity increases, but the equipment may be over-stressed and damaged
Solution Approach 1:
The startup process is divided into multiple distinct phases (boiler firing, boiler ramping, turbine rolling, turbine loading), each with its own predefined conditions and time calculations. This segmentation allows optimization of each phase independently while ensuring overall safety and efficiency.
2Reliability
If the startup process is extended to ensure equipment safety, then reliability improves, but productivity decreases
Solution Approach 1:
The system dynamically calculates and adjusts the duration of each startup phase based on real-time operational data and predefined conditions. This allows the startup process to be as fast as safely possible, adapting to actual equipment responses rather than following fixed, overly conservative schedules.
3Adaptability or versatility
If manual monitoring and adjustment of startup phases is used, then flexibility and adaptability are maintained, but loss of time occurs due to human response delays
Solution Approach 1:
The system continuously monitors operational data during each startup phase and automatically adjusts timing and conditions based on real-time feedback. This closed-loop control eliminates manual response delays while maintaining the flexibility to adapt to actual equipment behavior and conditions.
Solution Approach 2:
Manual monitoring and decision-making processes are replaced with automated computational systems that calculate phase durations and evaluate conditions. This substitution eliminates human response time limitations while preserving adaptability through algorithmic decision-making.
