由于海南电网容量较小，使得机组的一次调频存在动作频繁，单方向动作的时间长、幅度大的特点，且在运行方式上存在联网和孤网2种运行模式，一次调频控制相对较复杂。对此，在分析海南电网运行特点的基础上，对华能东方电厂超临界4×350 MW 机组的一次调频控制策略进行优化，以解决频繁的小幅度一次调频动作的问题，提高一次调频的控制品质。同时，对机组协调控制进行相应的优化，在保证一次调频控制品质的基础上，提高了机组运行的安全性、稳定性。

Small capacity of Hainan power grid causes several problems,like frequent primary frequency reg-ulation of the units,long time and large amplitude of single direction movement during primary frequency regulation,and others.Furthermore,as the power grid has two operation modes (networking and isolated grid),the primary frequency control is relatively complex.Therefore,on the basis of analyzing the opera-tion characteristics of Hainan power grid,the primary frequency control strategy of a 350 MW unit was op-timized,to solve the frequent small amplitude primary frequency regulation problem and improve control quality of the primary frequency control.In addition,corresponding optimization on coordinated control system was also conducted to enhance the safety and stability of the unit operation,on the premise of ensu-ring the primary frequency control.
