| Abstract: | Aiming at problems existing in the 700 MW ultra supercritical power units in a power plant, such as low load changing rate, low load regulation accuracy and instability of the control system caused by coal type changing, a coordinated control system and an optimal steam temperature control system are proposed through adopting the advanced control methods in the modern control theory. The practical application shows that the advanced optimal control systems have successfully improved the performance of load regulation and reduced the fluctuation of key parameters, which indicates that the operation stability and self-adaptability to coal variation of the units are greatly enhanced. |
| Keywords: | ultra supercritical power unit coordinated control system steam temperature control system predictive control neural network self-adaption |
