Beilun Power Plant, during its second construction stage of 3×600MW sets, encovntered the problem of depressed steam temperature, caused by some oversea technical design error.

Because the reheat temperature is lower and the stack gas temperature is higher in Hefei Station No.

For reheat temperature system, a novel internal model controller with decoupling is provided.

Now it has been successfully applied to reheat temperature control system in power plant.

Application of active disturbance rejection to reheat steam temperature control systems;

In tangential combustion system,the reheat steam temperature can be adjusted by changing burner nozzle angle to just the flame position.

By the combined use of a prediction control and PID controller in the control of a reheat steam temperature system.

Chaos optimization-based parameter optimization of predictive PID controllers for reheated steam temperature;

In order to solve the control problem of reheated steam temperature system with long inertia times and long time-delays,the model reference adaptive predictive control(MRAPC) method is applied for reheated steam temperature control system of 3# unit in Jingneng Thermal Power CO.

Through a series of retrofitting of the reheated steam spraying water control system and the titling burner control system, with the application of the KPA optimizing control technology and adjusting control parameters by building testing model, the variation of the reheated steam temperature are controlled in smallest scooe.
