摘　　要：目前燃气轮机机组主要存在反向自动发电控制(Automatic Generation Control,AGC)指令,以及无一次调频增负荷调节余量等问题,这些问题导致一次调频动作不正常。以9F燃气联合循环供热机组为研究对象,在原有一次调频逻辑的基础上进行了优化,即一次调频动作时,如判断有AGC反向指令,则抑制其调节功能,如判断无一次调频增负荷调节余量,则通过中压供热节流方式辅助调节。实际操作结果验证了优化手段能够起到较好效果。At present,there exist problems of reverse Automatic Generation Control(AGC)command and no margin of primary frequency regulation for load increase in gas turbine units,which may lead to abnormal primary frequency regulation.Taking 9F gas-steam combined cycle heating unit as research object,the primary frequency regulation logic based on the original one is optimized.When the primary frequency regulation acts,if it is judged that there is AGC reverse command,its regulation function will be suppressed;if it is judged that there is no margin of primary frequency regulation for load increase,the medium pressure heating and throttling mode will be used for auxiliary regulation.Practice result has verified that the optimization method is effective.
