AI Technical Summary

Technical Problem

Traditional gas turbine control systems rely on a centralized control architecture, which leads to data processing delays and difficulties in controlling multiple variables. This makes it difficult to achieve coordinated optimization of gas turbine combustion efficiency, emission indicators, and equipment lifespan under complex operating conditions, increasing the risk of energy waste and environmental pollution.

Method used

A distributed control system-based approach is adopted, which uses a distributed sensor array to synchronously collect gas turbine operating parameters, performs feature engineering processing through edge computing nodes, and uses an improved model predictive control algorithm to decouple control quantities. Combined with closed-loop feedback and parameter self-learning mechanism, real-time evaluation and signal feedback are performed.

Benefits of technology

It improves the dynamic response capability of gas turbines under multi-dimensional operating conditions, increases combustion efficiency, reduces environmental pollution risks, and enhances operational stability and adaptability under complex operating conditions.
