针对枫树坝电厂机组一次调频投入后频繁被误考核的情况，根据一次调频管理规定和考核办法，分析了机组的一次调频测试报告以及电厂的一次调频被误考核申述材料，发现了该厂机组在调速器开度闭环控制中加入一次调频使得理论动作电量的计算不符合实际，造成机组低水头下一次调频易被误考核；实际动作电量积分起始时刻相对一次调频启动时刻的延时会降低其占理论值的百分比，当调度记录的一次调频启动时间滞后电厂实际且超出稳定时间时电厂会被误考核；该厂的一次调频考核系统无自动免考设置，致使频繁发生机组符合免考条件的一次调频未动作被考核且需人工申述的情况，最后给出了避免错误考核的针对性措施建议。

After primary frequency regulation (PFR) was put into operation ,Fengshuba Plant was often mistakenly assessed ,unit PFR test report and statement materials were analyzed according to PFR management regulations and assessment methods .It is found that adding PFR to opening loop control made theoretical integral power not fit reality ,cause units to be mistakenly assessed more easily when they generated low heads .The action time that dispatches recorded lagged plants more than stability time would cause a mistaken assessment .Finally this paper provides suggestions for avoiding mistaken assessment .
