| 摘 要： | 为揭示给水泵系统在机组负荷变化时的动态性能,建立了某凝给水系统中给水泵的动态模型,采用既调阀又调泵的给水调节方式,对由于机组负荷变化引起的给水泵的动态响应进行了仿真,结果表明,该模型能够较好地反映泵的实际动态过渡过程,对于分析给水系统的动态性能和进一步设计控制器具有一定的意义.

| Abstract: | In order to give the transient characteristics of the feedwater system during the load of unit changes, the dynamic model of the feedwater pump in a certain feedwater system is stated ,the control of the feedwater is achieved by regulating both the pump and the feedwater regulating valve, and the response of the feedwater pump when the load of the unit was changing is simulated.The results indicate that the model can reflect the real transient process correctly, and it is valuable to the analysis of the transient characteristics of the feedwater system and the design of the controller . |
