摘　　要：为提高凝泵变频改造后凝结水系统自动投入效果,降低厂用电,提高机组效率,对凝结水系统运行方式进行深度分析的基础上,实现了凝结水系统的一键自启功能,并提出压力/水位协调控制与稳流调节的引入,较大程度地提高了凝结水自动控制系统的鲁棒性。Since the frequency converter being instaI ed to the condensate pump,this paper appIies through anaIysis on the operation of the condensate system,by improving the automatic function of the system,the power suppIy for the unit have been reduced whiIe the efficiency of the unit increased.MeanwhiIe,the condensate system can be put into operation by one singIe action,together with the coordination controI of the pressure/water IeveI and the appIication of the stabiIization reguIation,the robustness of the system have been improved dramaticaI y.
