摘　　要：华能海门电厂目前装机为4×1036 MW机组,低负荷工况下运行会产生很多不利影响。对协调控制系统、给水、汽温、氧量、一次风压等系统的控制系统进行合理深度优化,使其既能满足机组高负荷段的自动调节性能,也能满足低负荷段的自动调节性能,实现对高低加水位自动稳定调节、给水泵再循环最佳开度等,使其在高、低负荷段均有较好节能能力,达到了低负荷深度节能降耗的目的。Currently four 1036MW units have been installed in Huaneng Haimen Power Plant, generating many negative factors under low load operation. In this research, reasonable and deep optimization was conducted on the coordinating control system, water supply system, steam temperature control system, primary air pressure control system in order to meet the unit automatic regulating performance under both high and low load opera- tion, automatically and stably adjust the high-low water level, optimize the opening of recirculating valve to get better energy-saving capability under both high and low load operation, and meet the purposeof energy saving under low load operation.
