摘　　要：首先介绍了云南电网发电侧水火电基本情况和在频偏系数增大的条件下CPS考核新形势,分析了现有的AGC控制策略及外送通道压极限运行的风险。为提高CPS性能指标和减少外送通道越限风险,结合云南电网水火电机组的实际情况,提出了三种AGC与一次调频配合优化方案,并指出了这三种方案各自的特点。在电厂和调度端试验后,选择了其中一种方案作为实用方案,并取得了较好的效果。In this paper, the basic situation of water and fire power plant generators in the power generation side and the new situation of CPS assessment under the condition of the increasement of bias coefficient in the Yunnan Power Grid are introduced. The characteristics of the existing AGC control strategy and the risk of closing to the limit of outgoing channel are analyzed. In order to improve CPS assessment and reduce the risk of the more limited, three better programs of coordination AGC and primary frequency regulation are presented considering the actual situation of water and fire power plant generators. Their characteristics are also pointed out. After experiments are made in plants and power distribution department, one program is chosen,which is effective in practical application.
