摘　　要：针对凝结水泵系统节流损失大,耗电率高的问题,引入多模控制理论。对某电厂凝结水泵系统进行变频改造,提出多种模式不同工况下被控对象的控制方法。应用中,此控制方法大幅减少系统的节流损失,具有优良节能效果,提高了系统的稳定性和控制能力。Aiming at the problems of high throttling loss and high power consumption in condensate pump system,the multi-mode control theory is introduced.The variable frequency transformation of the condensate pump system in a power plant is carried out,and the control method of the controlled object under various modes and different working conditions is proposed.In application,this control mode greatly reduces the throttling loss of the system,shows an excellent energy saving effect,and improves the stability and control ability of the system.
