摘　　要：根据发电厂磨煤机系统启停及一次风量对机组运行稳定性的影响 ,对控制系统进行了试验研究。提出了降低磨煤机启停最小风煤量和一次风量作为机组变负荷时快速暂态干预手段的改进方案 。Based on the influence of coal pulverizer's start-stop and primary air flow upon the operation stabililty of units in thermal power plants, an experimental study of the control system has been carried out, and a modification scheme to reduce the min. flow of air-fuel mixture during the start-stop process of coal pulverizer is put forward, taking the primary air flow as a rapid transient interfere means during the time of unit's load variation, the suitability to load variation and capability to external interference rejection of the said system having been strengthened.
