摘　　要：西南异步联网运行以来,系统频率波动加剧,机组AGC与一次调频动作幅度、次数显著增加,AGC和一次调频不协调的矛盾突显,对系统频率支撑带来危害。通过升级优化监控系统机组现地控制单元CPU固件版本及PLC程序,在监控系统侧计算一次调频动作对应的有功功率,与AGC/人工功率给定值进行数学叠加,从而实现AGC与一次调频的协调配合。Since the synchronous interconnection of the southwest powergrid,the system frequency fluctuations have intensified,the amplitude and frequency of the AGC and primary frequency regulation have increased significantly,and the contradiction between AGC and primary frequency regulation has become prominent,posing a threat to the system frequency support.By upgrading and optimizing the CPU firmware version and PLC programs of the unit control units in the monitoring system,the mathematica laddition of the active power corresponding to the primary frequency regulation action in the monitoring system is calculated,and the AGC/manual power setting value is added,thereby ultimately achieving the coordination of AGC and primary frequency regulation.
