摘　　要：针对五凌发电集控中心某水电站机组频率达一次调频动作值后,监控系统调整有功指令无效现象,分析目前一次调频和机组AGC或人工增有功存在的配合缺陷。对不匹配问题进行了优化改进,通过试验和实际运行,取得了良好的效果。Aiming at the invalidity of the active power command adjustment of the monitoring system after the frequency of the unit of a hydropower station in wuling power generation control center reaches the action value of primary frequency modulation,the coordination defects of the current primary frequency modulation and unit AGC or artificial active power increase are analyzed,and the mismatch problem is optimized and improved. And through the experiment and the actual operation,has obtained the good result.
