AI Technical Summary
In traditional dual-adjustment turbine speed control methods, there is a time delay between guide vane opening control and blade opening control, resulting in low blade opening control accuracy. This makes it impossible to accurately reflect the influence of guide vane opening and head on blade opening in real time under complex and variable operating conditions.
The PID control module outputs the target guide vane opening control signal, the guide vane opening control module controls the guide vane opening according to the real-time signal, and the co-control module calculates the target blade opening based on the real-time head and power signals, and performs parallel adjustment through the power-head-guide vane opening co-control model and the guide vane-blade opening co-control characteristic model to reduce system delay and improve blade opening control accuracy.
It significantly improves the response speed and accuracy of blade opening control, ensuring that the turbine can quickly and accurately reach the optimal coordinated state under various operating conditions, thereby improving the dynamic stability and operating efficiency of the power generation system.
