摘　　要：介绍了机组一次调频能力的考核指标,分析了机组在不同运行方式下,一次调频实现过程中存在的问题,并针对流量偏置因子、机组滑压运行、DEH与协调控制的配合、负荷"反拉"现象以及提高小范围频差调频能力等方面,提出了有效的解决方法和对策,对在各种运行方式下,全负荷段改善机组的一次调频能力,提高电网的稳定性有极大的帮助。The evaluation index of unit＇s primary frequency was introduced. And the problems in realizing unit primary frequency under different operating mode were analyzed also. For solving these problems, the effective methods and countermeasures were put forward. The full load section＇s primary frequency ability under different operating mode will be improved by using these methods and it is helpful for the stability of the power grid.
