| Abstract: | In order to solve the problems during operation of boilers,this paper introduced advanced steam drum boiler control system with three impulses feedwater.According to the working principle of steam drum boiler control system with three impulses feedwater,the Simulink simulation of control system is designed.At last,the control system is simulated within MATLAB environment.Results showed that three impulses cascade plus feedwater control system can promptly eliminate the interference between vapor load and rate fluctuation of feedwater,to make the control water level meet the stable operational requirement with high quality and accuracy,which also can guarantee the safe and stable operation of the boiler and prolong the service life. |
